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

Discuss briefly inelastic collisions in one dimension.

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

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

A body of mass 2 kg, travelling at 4 m/s makes a head-on collision with a body of mass 1 kg travelling in the opposite direction with a velocity of 2 m/s, the velocities of the two bodies after collision are

Discuss briefly the elastic collision in one dimension . Also , analyse their special cases .

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.

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 ?

Show that in case of one dimensional elastic collision of two bodies, the relative velocity' of sepa¬ ration after the collision is equal to the relative velocity of approach before the collision
