Conservation of Momentum
When two bodies act upon one another their total momentum remains constant provided no external forces are acting on it.
Let the velocities before collision be u1 and u2 respectively.
Velocities after collision be v1 and v2 respectively.
Masses will remain same after the collision.
Initial momentum = m1u1 + m2u2
Final momentum = m1v1 + m2v2
FAB = -FBA
m1a1 = -m2a2
m1 [v1 - u1]/t = -m2 [v2 - u2]/t
m1v1 - m1u1 = m2v2 - m2u2
m1v1 + m2v2 = m2u2 + m1u1
Hence proved,
Total momentum before collision = Total momentum after collision .

Hello magnet brains. I have been a big fan of yours... You guys are so good. But can you pls explain if both ball cime in rest after collision how can it be same initially and finally. Pls say
@MagnetBrainsEducation
Жыл бұрын
Thank you for being a fan of our videos! We're happy to hear that you appreciate our content. In regards to your question, when two balls collide and come to rest, they are initially moving at the same speed. However, they have different masses, so the heavier ball will have more
How i you teach is so impressive... Tomorrow is My science exam and i have watched all your vdeos of my tomorrow's exam chapter ....but i guess in 2023 conservative of momentum is reduced if u know please tell mee... Bcs i m not sure about it❤❤
