Projectile motion (part 10)

[samlinkworth]

Thank you and JAZAK ALLAHU KHAIR :)

[Kricardose]

I am very happy to see the vidoe Some more examples with projectile motion after you give this

[bebeheuy]

I Love The Video It Can Increase My Knowledge Some more examples with projectile motion

[Mjhond]

Steady I Really Like This Video Some more examples with projectile motion

@ThePeracha so did I.. lol

[virtuosoikingpin]

I swear I don't believe that our physics teacher even understands physics. Whenever he does these problems he just pulls out the formula and enters in the numbers, and doesn't even to attempt to explain the formulas. It's the same as just teaching kids to do math with a calculator and never teaching them to add or divide themselves, or what the numbers represent. Gahhh bad teachers frustrate me, thank goodness for you.

could you solve some problems involving a intial hieght where the ball is launched over a certain distance it is thrown with a certain angle, and reaches a certain height above the horizontal?

[r4m4nNo0dL3s]

@Denseworldproduction that deals with parabolic motion



[R2SweetTooth]

I tried solving t with the formula V(final) - V(initial)= at, but found that time became negative. For the equations to be right when using this formula, it needs to be pointed out that V(final) is negative 24,5m, which isn't written in the video.

[essssa2009]

When he wrote Vf2= Vi2+2d by mistake, i was like WTF hahahhaha.

thanks man.

[charcoalfilter1101]

thanks mr. khan for showing to us to derive formulas. physics is now totally easier to deal with because of these derivations that you'd presented very well.

This was by far the best of the 1-dimensional projectile motion videos. 5 stars all the way!

[mambizzy]

at around 2:54 you say the acceleration due to gravity is -10 m/s^2 but it is actually positive since you are not going against gravity.

[Kirkdabossplaya]

When doing equations of motion. Write down what you know at the side of the question:

U

V

a

t

s

Uvats. U = initial velocity , V = final velocity, a = acceleration, t = time , s = displacement

If you write uvats and state what you already know then you can visualise what you have and what you dont have. Makes it really easy to select your equation you need. If anyone wants a tutorial sheet on this just ask and I will e-mail it to you.

@Kirkdabossplaya

can you please send me the tutorial sheet

[Kirkdabossplaya]

@Kirkdabossplaya I haven't got that tutorial sheet anymore. I have no idea where it is. If you send me any questions you have I can write you a script that explains how you can answer them using the method I stated above. Or I have some example questions I can answer for you. Let me know.

[roro252]

sal.......you are smart :)

[anthonychemistry]

i am really speechless...This part of the video is the meat of every kinematics and projectiles. That was really a killer move.. you are the best SAL..

[mrmicco45]

"this is a little too bloody!" haha

thanks for all the help man. im going to college this fall and im majoring in physics education and hopefully i am as well at explaining things as you are cuz you def help out a lot. thanks

[megaelliott]

lol the "hey.. you" at the start made me laugh. Thanks for the vids. They have really helped me

[phanikir]

cool man.. awesome.. better that you even introduce chemistry ...

[PorterWashington]

Awesome tutoring and pedagogical skills. Makes Physics easy. I still hate Physics though.

[d3c4p3t4t0r]

You can also calculate the final velocity using (m*v1² + m*g*h1) = (m*v2² + m*g*h2). I think it's cool you can calculate the same thing using completely different formulas.

[Havardgurl]

i cant figure any of this out!!! I have an homweork assignment fro physics and im not getting it..i have to find teh range of the cannonball and i have teh time...and i know u are suppose to ad the but my answer is wrong...so i need help badly!!!

[quarkqueen]

Thanks for all the projectile motion vids.

I found them really helpful for my upcoming physics exam :)

[ezboss7]

hahahaha!
