 And I have not started the recording, now started a person sitting in an open car moving at constant velocity throws a ball vertically up into the air the ball falls the ball falls Outside the car, in the car ahead of the person, in the car to the side of the person exactly in the hand which throw it up Now don't say that we threw the car outside the car What happened to Mungara? Mungara is not logged in with the infamous name of his That's a beautiful comment Meghna, like wow 228720 guys I told expect that you are not throwing it out A person sitting in an open car moving at constant velocity throws a ball vertically up is a ball Not horizontally right word or left word It is vertically up, it's thrown vertically up So it will the car, this is the ability of Maya to draw a car I can't draw better, so my masterpieces are just like this Ball is tossed, this ball will retain its inertial motion toward this direction So it will go like to, meanwhile in the same time our dear car will also reach the same spot So it will land exactly in the hand with which through It was thrown up, G I got it, got it, got it, got it, got it, got it Good, wind resistant etc, get a better leather ball What would happen if it was accelerating even then in that case dear My new differences will be there at insignificant, like at big distances If air resistance had to be considered aria, it will be very thoroughly mentioned If it has to be considered, and the ball is not a paper ball that it will just fly off Better ball, I draw the diagram Sneha, like I represented it by the diagram This is a car, car, okay When the ball is with the car, both the car and the ball are moving with same velocity When you throw it up, the ball retains its initial state of motion So this ball will now do two types of motions parallel Hence it will land up here Now the velocity in this direction is same as that of car Because it is received from car only So in the same time they will cover equal distance in the horizontal direction So, good, good, good, good Thank you very much, thank you very much, next Here we go to the leaderboard Ananya, better car is moving, do one thing Utilize this, like after the class Throw ball upward, keep running, throw ball upward and go You will take it catch back in the same and you won't have to stop I repeat it, I will repeat that back, understand Yes, see here, if the car would have been static The ball will go up and will come down But because the car is having some initial velocity direction here This ball also have initial velocity direction here Okay, sure The ball will go like this and come here If your car will stop just after throwing the ball You won't be able to reach the ball You won't be able to reach the ball But because your car is moving The ball was moving, both have the same horizontal speed They will land up, they will reach up at the same horizontal ground In the same time, yes or no Good, thank you, thank you, thank you, relax And I suggest, if it is escalated just after throwing the ball Then a difference in value, in that case the velocity of car will increase It will cover some more distance in the same time Okay, if it will de-accelerate It will fall before the ball, right or not Okay, the ball will fall in front of the car Got it Aryan, bit has thrown vertically up Needleboard shows Siddharth was the fastest one to respond Okay, there are other friends of ours Now the difference has increased to thola thola sa And let's move on to the next question A particle is moving with a constant speed along a straight line path A force is not required to increase its speed Decrease the momentum, change the direction Keep it moving with uniform velocity Somewhere I got distracted because of the voice, sorry for that So yes, increase its speed, decrease the momentum Change the direction, keep it moving with uniform velocity 46 people answered it right, like the 45 people answered it right In the first question, 46 people now, learning it out 5, 5 and 1 Guys, please relax, think, read and respond By the very first law of Uncle Newton, it says that A body will continue its state of motion until and unless a net external force is applied Increasing the speed state of motion is not kept the same It has changed, decrease in momentum again, change in velocity Change the direction, again change in momentum Changing the direction will need a force to be applied The only thing is, if it has to be let moving like the ball and the car No force is required Okay, so here we go to the next question And before that, the leaderboard No numerical, sir, there will be a They will come, they will come, they will come And they will surely come Dialogue from, dialogue from General knowledge test is like I will give you a hint Loki In conversation with Gone, I am not in conversation with these guys No, Loki is in conversation with No, they will come and they will surely come Iron man We have an army of aliens We have Avengers They will come and they will surely come They don't know anything, I am not going to talk to them Now Aniket Gupta is the fastest one to respond Pranav, Smriti and quite a good number of people Next Who yaar? Like not Avengers to Avengers If a bullet of mass 5 gram moving with the velocity They will come and they will surely come They came If a bullet of mass 5 gram moving with velocity 100 meters per second Penetrates the wooden block up to 6 centimetres Then the average force imposed by the bullet On the block is The average force imposed by the bullet On the block is Numerical, numerical, numerical 11, 25, 18, 2, good Relax And read Relax Bullet of mass, mass will be required at last Because it is calculation of force We will have to calculate the acceleration Mass multiplied by acceleration will give us the answer So Good Now with the velocity, there is an initial velocity Penetrates to the wooden block up to 6 centimetres That means before coming to a final velocity of 0 The displacement carried out is 6 Yes or no I mean 417 is everyone knowing this Rn, you are out somewhere You are responding here Right? Good, good, good, good, good, good Very good, very good, very good Chalo By utilizing uncle Newton's or the equations of motion Third equation we will write V square is equals to u square Plus 2 A S Yes or no? Yes or no? From here What is the value of A you will calculate And then multiplied by mass into acceleration Will give you the total force Yes or no? Gupta So now Gupta's your ideology is calculate time How will you calculate time? S is equals to ut plus half 80 square Now you think, you tell me how will you calculate time? Where will you get A from? No, so that's Okay, relax first thing Because you will get good and beautiful Where did you get A from? Yeah, exactly For Gupta you are saying, right? Okay, relax, understand guys We have three equations We have had these kind of discussions Okay, I should not invest time in this Some time later But understand, all the three equations of motions Are four variable at a time In order to get some answer out of any one equation You need three informations bare minimum Yes or no? You know the process of solving an equation, right? Yes, Gupta What am I saying to you? I am not talking about why Like you applied something wrong Our agenda of discussion is The Approach Right? And I know Gupta won't mind it Taking the name over here Thank you very much So now we will get acceleration from here What is the value of acceleration coming out from here? What is the value of acceleration coming out from here? Negative 100 Into 100 Into 100 By 12 Yes or no? Yes Good Everything in this system is at SI So the force will be equal to mass 5 gram Into Acceleration 3, 4, 5, 6 By 12 So You have the answer How? 10 to the power minus 3 And this will get cancelled It will be 5000 By 12 Which is Bought it GI Good guys Relax Now you are exaggerating Exaggerating and Kind of Bugging one of my very dear friends Right? Okay Meghna, here we go So Mass was given Initial velocity is given Final velocity is 0 Displacement is given So we will apply third equation of motion V square is equal to u square plus 2 as Good No I like you were kind of noting it down Okay Okay got it Thank you Here we go to the leaderboard So Aniket Pranav Smriti Aniket you Got this bad Now you will see who is going to harm you Okay Good Vibha Vibha was the fastest one to respond Neha, Gyanesh, Pranava there And here we go To the next question A force of 100 dimes Act on Mass of 5 gram For 10 seconds The velocity produced is Beautiful prism Dime is a CGS unit of CGS unit of Force Like force is calculated in kg meter per second Square If you will calculate force in gram Centimeter per second square Then you will get Gram centimeter per second square Then you will get Okay So like this is a beautiful question Delivering two types of information for you guys So force of 100 dimes Force is acting on a mass M is given For 10 seconds The velocity produced is Good Good Good 31 people Chop Back First beautiful scenario Dime Okay Chop But the more beauty is You don't have to convert it Because the answers are in centimeter per second Yes or no Now you have this concept as Force is equals to change in momentum Upon time Second law of Uncle Newton Yes or no And you know While doing so While doing so You don't change the mass So change in velocity Is equals to force into time By mass Okay Force Into time By mass Easy Easy Easy The confusion see The beauty of the scene is which They created a confusion But they nullified it by that Itself Okay Right Good Need a board Okay Somewhat a shuffle is possible Aryan, Aniket, Naina Pranav Neha is leading the scenarios Very good They were being annoying and nice At the same time Who? Okay Mungara is like Mungara Talking like Mungara Good Varsha was the fastest one To respond And here we give To the next question Objects will continue moving Uniformly until It will continue to move Uniform until There is a twist Oh Surya Like this is This is a bigger problem Right Guys, read it The resultant force acting on it Begins to decrease The resultant force on it is 0 I couldn't read it I took some time but answered it Let's see 27 people answered it 10, 6 and 12 Please guys The object will continue moving Uniformly until No force acting on it Acts on it Okay Clear The other way Some force really exists The resultant force acting on it Begins to decrease Still force exists The resultant force Is at right angle To its rotation So it will be at Causing a circular motion The resultant force on it is Increased continuously Force exists So in all the three scenarios other than B There was a presence of force Okay Right Here we go to the leaderboard Neha, Pranav, Gyanesh Pranav Okay there are two Pranavs Gyanesh is now leading the scenarios And here we go to the next question In doubling The mass and acceleration Of the mass The force acting on the mass With respect to the previous value Decrease to half Remain unchanged Increase to two times And increase as four times Neha sir I choose B But it shows AAR Sorry Neha, sorry, sorry, sorry Is this some trick question Sola sir there is a The language is a bit messy Okay It's messed up, it's not like Very straight So like it takes a time Some time for someone to Really go through that what to be applied What to be multiplied What to be divided and all It's not a tricky question The language is not that clear The only thing is Right, good, 47 Both the mass and accelerations Are being doubled To M and to A So the force will become Four of the initial value G, I got it Good So we are running good with respect to time But yes there will be questions In the later stage where Explanation will have to be comprehensive So Gyanesh, Pranav, Pranav Naina Pranav is now leading the scenarios Very good, very good, very good Let's go to the next question A force of 5 Newton acts on a body Of weight 9.8 Newton What is the acceleration produced In meter per second Relax, think and respond You will get it Better when it is very straight forward Written 9.8 Then it's good to go take the G as 9.8 It will be easier to calculate You playing a different game Yes, simple and easy 9.26, 8 and 13 Because the word here says weight Word here says weight You will have to go to mass What is mass? Weight is mass Into acceleration due to gravity So from here Mass of this body will be 1 Ok So Mass Into acceleration is force So acceleration is 5 G, I got it Need a board Pranav, Pranav, Gyanesh couldn't get it Naina, Varsha The fastest one to respond was Aditya, very good, very good Here we go to the next question You are on a frictionless horizontal plane How can you get off If no horizontal force is exerted By pushing against the surface? Yeah, logical Good You guys got it Anyone want to unmute and explain Anyone, anyone Since the friction is not I mean it's a frictionless surface So the only way you can move is By exerting a force in the opposite direction Which you can achieve by either Setting or sneezing Exactly Got it, every action will deliver An equal and opposite reaction Your body acts this way You will move this way Okay So there is no other way possible Got it So Good Next question Gravity won't stop you from sliding That is what you are using Pranav, Naina, Rn And here we Rn was the fastest one to respond Very good, very good Here we go to the next question Pran is standing at a spring Platform, spring balance and all that Right The reading of spring balance is 60 kg weight Okay If Man jumps outside the platform Then the reading of spring balance Will first increase then decrease to 0 Decrease Increase remains same I guess In order to make you guys wait I should have kept the option number A Somewhere in between I don't know whether it is right or not But just telling like that Guys No No Not at all Okay There are 15 questions 46 people So like 45, 46, 47 people Answering to those questions Yes As you will jump You will apply a force downward That will increase the reading Of the weighing scale Okay And as you will Release The system will remain Like will come at neutral stage So it will first increase And then decrease I got it Pranav, Rn, Pranav, Naina Khushi, Aniket, Gyanesh, Siddharth Sneha was the fastest one to respond Very good, very good, very good And here we go to the next question A machine gun fires 20 bullets Per second Into a target Each bullet weighs 150 gram And Has a speed of 80 meter per second Find the force Necessary to hold the gun In position Relax, read and respond You will get it, not a very difficult one The bullet is just too heavy It's a machine gun also Read that Which kind of machine gun You have seen a small PUBG machine gun 37 people got it right Very good, nice at calculations What kind of bullet Is 150 gram Like you guys Need some visit to some camp and all Okay A machine gun Fires 20 bullets per second Into a target Good Each bullet weighs 150 gram And has a speed of 800 meter per second Here So, no doubt No understand Forward momentum Is equal to backward momentum And you call it required So, whatever be the forward momentum Will be the backward momentum Okay Sure, in order to Hold the gun, whatever Is the force being applied In doing so Will be equal, every action will have An equal and opposite reaction Yes or no Now Total mass being ejected Per second Total mass being ejected Is 20 into 150 into 10 to the power Minus 3 gram to kg Okay Per second So, into Velocity 800 meter Per second Clear, now easy to solve Why, because 1, 2, 3 will nullify this This is 300 Multiplied with 8 2400 Gi, got it No doubt, good Oh, that's You miss the 8 Then 300 is nowhere If you miss the 3 Then 800 is available, no problem No problem, good Need a boat Pranav, RN, Pranav, Naina, Khushi Ganesh, Neha, Kiranmay Neha, Laksh Ganesh was the fastest one To respond, and here we go The first machine gun had a big barrel Of water surrounding The nozzle to cool it Good, tension in the spring Is, tension is the stretch Okay Stretch, I am feeling Somewhere that the question is incomplete Got it, I got it The question was incomplete No problem, no problem, no problem Yeah, relax, relax The question was incomplete Relax, relax, relax Not your mistake, guys Relax, the question was incomplete Okay, why Because if this Spring is getting stretched Then how much is not given You getting my point So might be that while Somewhere converting The color and all It got missed See, it can be all possible options RN, with respect to the reading Given, it can be all possible options So, yes Exactly, what is tension First of all, so understand this Pachai, if Simple, what I Relate, you guys will relate easily To this, if there Is a rubber band You will pull it, it will break Yes or no, right Sure On application of the force There exists a Response, like Spring, specially spring Okay, specially And easy to understand with spring Spring, rubber band and all that Okay, suppose There is a ceiling, there is a thread And there is a mass hanging M Yes or no, yes or no Now my simple question is What is the force acting, what is the force acting What is the force Okay What is the force, what is the force acting Down is mg But if mg is the downward force Shouldn't be a case that this object Should go down as per Newton's first law Yes, it should go But where is this force getting neutralized This force is getting neutralized By generation of a restoring force Right or not There is a thread in the string Okay That is the tension in the string The very word tension, the stress Okay, the opposition to Applied force Right, exactly So now, understand this If by application of this It will not stretch At all If by application of these forces It will not stretch At all, the answer should be 10 Should be 10 Okay And then further With respective increase In the stretch It will become Till 0, how Force is not 0 Force on the system is 0 There is a string It will stretch It will stretch No, no, answer is not d, that's what I am saying But the information is missing This question is not complete Okay, so One by one If there is no expansion If there is no expansion 10 Sure If there is Suppose, understand Very simply understand This is a loose pack of wool This is a loose pack of wool Yes or no This is a loose pack of wool Then, will it experience any stress Because of a force being applied on it No, it will easily open up unwind Yes or no In that case, there won't be any tension Getting produced Okay, exactly There has to be information given About the material Okay, how is it expanding How much is it expanding Some arrow diagram over here and all that Got it, aren't you not getting Aren't you come back to a normal scenario Okay Very normal scenario But this is a ceiling This is a wall Okay, it's a rigid wall Okay, there is a hook Clear With the hook, there is a Iron rod Okay You are at one end of this iron rod You are at one end of this iron rod Okay So And now you are pulling it Is the iron rod moving Yes or no Means whatever the force you are Applying is getting neutralized In this direction Yes or no So whatever is the applied force Is equal to the tension in the rod Yes or no Now think about a little different case There is a thick rubber band Thick Very very thick Because resultant has to be Zero Therefore tension is required If tension won't be zero Who will If tension won't be zero Who will decrease the Impact of the force Right Got it, that's it So now whatever be the stretch Based on that the amount of Tension will keep on decreasing Okay, so suppose Free wool Okay, you will just run with the force So whatever force you are applying Is getting utilized to stretch it No tension Got me Good, good, good, good, good, good So What I will do is I will try to Nullify the impact of this question Better rigid collectors will have Maximum tensions The capability of the Their capability to Okay Retain that is maximum What I am doing is I am nullifying the impact Of this question, okay So no one will get any score out of this I have like Kept the switch screen off Over unsure mode Because I was Okay, now I have given everyone wrong Is it okay neutral Right, good Next question So now see We landed up in that single question Hit us so bad That we are here But yes is still recoverable We have only After this like two more questions Three four minutes more Okay A book is lying on the table What is the angle between the Action of The block Of the book on the table Of the table on the book Beautiful question So confusing but beautiful Now you know in between when I was Discussing with you The last scenario I got some odd 52 messages Or what's that like Ting ting ting ting ting ting Ting So yes a book is lying Okay on the table it is applying its weight down What will be the Direction of the reaction Angle between them Okay 20 30 I told you there is a minor Confusion guys Minor confusion The confusion is Understand This is a table surface This is the book The MG of the book acts down The normal reaction by the table acts up The total angle between them is 180 Not zero I told you No confusion is there Got it Got it Here we go To the next question So Pranav is consistently maintaining his position Last two questions A body whose momentum is constant Must have a constant A body whose momentum is constant Must have a constant Force Velocity Acceleration all of these See the single word all of these Is the only Point of confusion If all of these wouldn't be there I know all of you might have answered the Single thing But the single word Single word Single word All of these Some message none of these If mass is not constant Yeah exactly Anike Good Good I said that single word Single word Single word Single word 24 people only My dear friends If there will be a constant force or Acceleration Change in velocity will be there Change in velocity will bring change in momentum Right Must be Constant Told you the single word Caused the doubt Got it Relax that's why it is required Please read Think, respond, beautiful Need a board I guess there might be a good shuffle See Aran's bullet concept I must comment on this He hardly makes a mistake Aran Good is leading the scenarios Anike Bhukta was the fastest one to respond And here we go to the It goes missing The Investigation leads you back To three generations above Okay I'll just put The connection The motion of a rocket is based on The principle of conservation of Principle of conservation of Rocket Rocket is principle of conservation of The Mass also changes So the Product of Product of Anike How many people got it right Leaderboard and I know because there is No explanation required for this Okay Right linear momentum Who's there, who's there, who's there, who's there Who's there Aran Tandon is the winner Aran is the new one Let me do it again Okay Good Aran Very good, very good Played well Guys I did not keep the miscellaneous question Because I kind of have noticed your response is good So we'll continue This NTSC rounds Learning outcome 1 to 5 Learning outcome 1 to 5 One being the smallest 5 Being the highest Excuse me sir can you hear me Yes Peter please Can you repeat the 14th one please 14th one Okay A board E whose momentum is constant Must have a constant Constant force supply Will bring change in velocity Constant acceleration supply Will also bring change in velocity Only keeping the velocity constant Will help Yeah okay sir thank you Good good Sir but force and acceleration are 0 right And 0 is also constant Yeah I am now joking Okay That's a particular solution not a general solution So now what have you been through this Particular solution and general solution If you might have solved trigonometric equations Yes or no Yes sir So that is a particular solution Okay so you can say Must have a constant supply Of 0 force A constant supply of 0 acceleration Because that's a particular solution Okay Good good No problem guys played well Very good very good thanks a lot good night Bye bye
