Question

Prove that momentum before & After collision remains constant​

Answer 1

Explanation:

For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.

Answer 2

Explanation:

Momentum: The product of mass and velocity of a moving body is called momentum.

Momentum = Mass of body × Velocity.

p=mv

Law of conservation of momentum: The law states, in absence of external forces the momentum of the system is conserved. It means that the total momentum before the collision is equal to the total momentum after the collision. Suppose two bodies A and B of masses m1 and m2 are moving in a straight line in the same direction with velocities u1 and u2,the velocity of the body A is more than that of B. So both the bodies will collide after some time. Velocities of the bodies A and B after collision become v1 and v2, respectively. The time of collision is t.
