Question

How does th collision? 1. e total momentum before the collision compare to the total momentum after the For an elastic collision: For an inelastic collision What factors in your experiment may cause a difference between the momentum before and the momentum after collision? 2. How does the total Kinetic Energy before the collision compare to the total Kinetic Energy after the collision? 3. For an inelastic collision: 4. Suppose both the projectile and target are initially moving in the same direction. Write an expression for the final velocity for an inelastic collision when the masses ot equal. are n

Explanation / Answer

Problem 1

As per the law of conservation of mometum, the total momentum of the system always remains constant in isolated situations. In both these cases , i.e. Elastic and non elastic collisions, the total momentum before and after collisions remains constant.

Problem 2

Friction may be the main reason.

Problem 3

For elastic KE is conserved, for inelastic KE decreases after collision
