Discuss briefly inelastic collisions in one dimension.

A collision in which there is absolutely no loss of K.E. is called an elastic collision. In such a collision, the linear momentum , total energy and kinetic energy, all are conserved.The coefficient of restitution // resilience of perfectly elastic collisions is unity. Read the above passage and answer the following questions : (i) When two bodies of equal masses undergo perfectly elastic collision in one dimension, what happens to their velocities ? (ii) How is this fact applied in a nuclear reactor ?

Discuss elastic collision in two dimensions. What are the conditions of glancing collision

Discuss elastic collision in two dimensions. What are the conditions of head - on collision?

Discuss elastic collision in one dimension. Obtain expressions for velocities of the two bodies after such a collision.

In case of elastic collision,at the time of impact

Statement-1 : In an elastic collision in one dimension between two bodies, total momentum remains the same before, during and after the collision. Statement-2 : In an elastic collision in one dimension between two bodies, total kinetic energy remains the same before, during and after the collision.

Two identical balls A and B having velocity of 0.5 m//s and -0.3 m//s respectively collide elastically in one dimension. The velocities of B and A after the collision respectively will be
