Conservation of Momentum in Elastic and Inelastic Collisions
In both elastic and inelastic collisions, momentum is conserved. This means that the total momentum of the system before the collision is equal to the total momentum of the system after the collision.
Elastic Collision
- In an elastic collision, kinetic energy is also conserved along with momentum.
- The objects bounce off each other without any loss of kinetic energy.
- The total kinetic energy before the collision is equal to the total kinetic energy after the collision.
Inelastic Collision
- In an inelastic collision, kinetic energy is not conserved.
- Some of the kinetic energy is transformed into other forms of energy like sound, heat, or deformation of the objects.
- Despite this loss of kinetic energy, momentum is still conserved in the system.
Explanation
- Momentum is conserved in collisions because there is no external force acting on the system during the collision.
- According to Newton's third law of motion, the forces between the objects in the collision are equal and opposite, resulting in a constant total momentum.
- This conservation of momentum is a fundamental principle in physics and is used to analyze and predict the behavior of objects in collisions.
Therefore, in both elastic and inelastic collisions, momentum is conserved, making it a crucial concept in understanding the dynamics of interactions between objects.

- Momentum is conserved in all collisions.
- In elastic collision, kinetic energy is also conserved.
- In inelastic collision, kinetic energy is not conserved. In perfectly inelastic collision, objects stick together after the collision.
Perfectly elastic collision:
If law of conservation of momentum and that of kinetic energy hold good during the collision.
If law of conservation of momentum and that of kinetic energy hold good during the collision.
Inelastic collision:
The law of conservation of momentum holds good during a collision while that of kinetic energy is not.
Coefficient of restitution (e)
The law of conservation of momentum holds good during a collision while that of kinetic energy is not.
Coefficient of restitution (e)
- For perfectly elastic collision, e = 1
- For inelastic collision, e < 1
- For perfectly inelastic collision, e = 0
