How to Derive Equations of Motion - With and Without Calculus

[pikamau51]

thank you! <3

[Kricardose]

I am very happy to see the vidoe that are used to describe the motion of particles in physics.I show how to derive the both with and without calculus.after you give this

[bebeheuy]

I Love The Video Here's how to derive the 4 major kinematic equations (aka: equations of motion) that are used to describe the motion of particles in physics It Can Increase My Knowledge

[Mjhond]

Steady I Really Like This Video How to Derive Equations of Motion With and Without Calculus

love dis

[rha207]

Very nice. Thank you.

[bladchou]

Man you are so good at explaining, thank you so much!!

To derive the 4th equation, you can also solve for t in the 2nd equation, where you get t = (2*delta x)/(v + vo). Then substitute that into the first equation, v = vo + a*t. Basically it would be v = vo + a( (2*delta x)/(v + vo)). This is a much easier way to derive the 4th equation, if you had to do the math. But if you keep in mind that all these equations are equivalent, just substitute any one into the other, and solve for the desired variable. It will work out just fine :)

its use full to me thanks dear i give it 5 stars 

[girlwelshdragon]

I thought it was really useful but I thought the gap with the time-independent equation was a bit confusing. I understand everything up until 5:15, but when you said it was messy so simplified, I don't understand how it simplifies into the formula you've shown. I know it's right (because that is the 4th equation of motion) but obviously the more steps you show, the more understanding there is. Thanks though, still really uselful.*GWD*

Thanks



[sample0nly]

Amazing, Thank you sooooo much!

[Davidcteviotdale]

why is it written so complicated?

y not just write it as

v = u + at

v² = u² + 2as

s = ut + ½ at²

why use delta and that :L

[david54626]

@Davidcteviotdale because the delta stands for the change in. It is more than just a place holder it signifies that there is change. You could not tell that by just having a regular V. Does that help? Plus its less stuff to memorize.

[ssaahhrraa9]

@Davidcteviotdale i was wondering that myself, beucase the equations you did are what my teacher showed us.

[jackofwack]

@Davidcteviotdale

Because the notation you've used would be wrong for the way he has derived them.

[Itswalrus]

Hello, I'm in Grade 11 Physics and I don't really understand the meters per second squared. For example 5m/s2. If you could help me with this that would be great. Thank You.

[DoctorTomm]

@Itswalrus acceleration is simply a measurement of how quickly the "speed" or velocity of something is changing. the unit is m/s^2 because time is changing as its speed changes, which is two time values. seconds * seconds = seconds squared. but you're diving by metres as metres is an indication of position, and an object needs a position in space in order to be affected by time.

This vid really helped!

sat in class today with flu and couldnt consentrate when the tutor was speaking, some repetition works out, thank you Alex ;)

[MrFarosco]

thank you very much,,it really helps me

[rampriyadarshini]

thanks a million.

[AlexPleaseHelpDotCom]

@rampriyadarshini You're welcome too!

[Swetlana0]

Thanks alot!

[AlexPleaseHelpDotCom]

You're welcome. :)

@Swetlana0 You're welcome!

[dunhill1]

That takes me back to my Physics class.  Thanks for sharing.
