Two identical particles move --------- to eachother after elastic collision in two dimensions.

In a perfectly elastic collision between two bodies

In an elastic collision between two particles

In a head on elastic collision of two bodies of equal masses

(a) Two identical balls are moving along X axis and undergo an elastic collision. Plot the position time graph for the two balls. (b) Consider five identical balls moving along X axis. What is the maximum number of collisions that is possible? Assume that more than two balls do not collide at the same time and collisions are elastic.

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.

Prove that in a two dimensional elastic collision of a moving ball with another stationary identical ball, the two balls move perpendicular to each other after collision?

Two particles are seen to collide and move jointly together after the collision . During such a collision, for the total system,

Two identical particles collide in air inelastically. One moves horizontally and the other moves vertically with equal speed just before collision. The fractional loss in kinetic energy of the system of particles is equal to
