This video covers:
- What momentum is
- How to calculate the momentum of an object
- The idea that momentum is a vector quantity
- What 'the conservation of momentum principle' is
- A worked example of how you can use the conservation of momentum principle to work out unknown momentum or velocity values

Why would anyone ever dislike this masterpiece?! Thanks, T&A!

[@loppol6035]

I disliked it because this isn’t how physics works. Momentum is actually, in truth, how much force is on an object carried with the help of the flat earth, it’s flat shape makes the ball go to the right. I hope this opens your eyes to the truth.

[@ishaanshanavas7573]

Yea because when moving to the right it is positive so the opposite side is negative

So according to my understanding in 4:40,it means that the gun dont just carried away with the bullet so its momentum is 0,like that?

[@chickenburger-dz6xn]

how did u say that the total momentum before=total momentum after, but in the gun and bullet example the total momentum of them after the action was not 0 ??? somebody explain please

[@x.elliek.x]

Hi hope its not too late to answer your question, but since the objects were both stationary before the event, their total momentum was 0. This means after the collision their TOTAL momentum must be 0, since the bullet moves forward its momentum was positive 0.6, the gun must move backwards so its momentum was -0.6 to show its the opposite direction. When you do -0.6 + 0.6, it equals zero in total. Remember the total momentum must be 0 (if objects were stationary), this does not mean each of their momentums are zero, it can just add up to zero.
