Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFExplanation:
- 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 collision.
- Hence, In inelastic collision of two particles total linear momentum only is conserved.
Perfectly elastic collision:
If law of conservation of momentum and that of kinetic energy hold good during the collision.
Inelastic collision:
If law of conservation of momentum holds good during 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
