explain both elastic and inelastic collision in 1D

Elastic collision - when two objects collide in one dimensional ( head - on), they often exchange velocities if masses are same. For example - if one ball of mass m moving at velocity v collides with energy ball of mass m which is stationary, then after the collision, the stationary ball will now move with velocity v but the ball which was moving initially will now come to rest.

Both momentum and energy is conserved in elastic collision

equation is given as

m1v1i = m1v1i = m1v1f + m2v2f

-----------------------------------------

Inelastic collision - This is a type of collision in which two colliding bodies stick with each other after the collision and move as one with common velocity. In this collision, momentum is conserved but energy is not because energy is lost as heat when two objects stick together.

the equation is given as

m1v1 + m2v2 = ( m1 + m2)v
