Topic Content:

  • Elastic Collision
  • Inelastic Collision

There are two types of collision namely elastic and inelastic.

Elastic Collision:

For elastic collision, the total momentum is conserved and the kinetic energy is also conserved.

Let us put into consideration two masses m1 and m2 moving with initial velocities u1 and u2 before collision and with final velocities v1 and v2 in different directions after collision.

For a perfectly elastic collision, we can write an equation from the law of conservation of momentum and the law of conservation of kinetic energy.
