Thank you very much for your help Sir!

Thank you so bloody got a physics mock tomorrow

For the balls example, we could also use the equation m1*u1 + m2*u2 = m1*v1 + m2*v2
Dont get confused, U and V are both fore velocities but to differentiate between before collision and after collision, so basically the left hand side is for before collision and right hand side for after collision. If we replace the values we get, 5*8 + 2*0 = 5*6 + 2*v2 because we need v2. 40+0=30+2*v2. Mke v2 subject of formula. v2=(40-30)/2= 5m/s

holy shit. you made that so much easier to understand. thank you!

Can you do a video on Waves please for A-level ??

2:54 is it change in momentum = force x time?

[SabrinaXe]

5:16 "and the principle of conservation of momentum"

HELP!!! why does he say the momentum of the 5kg ball is 40 before and after the collision, than works out the momentum is 30 after the collision on the 5kg ball. How can it be both 40 and 30??”
