Question

In an inelastic collision, after collision the kinetic energy

• A. increases by 2 times
• B. is less than before collision
• C. is more than before collision
• D. remains same

Hint:

For inelastic collisions, always remember that momentum is conserved, but kinetic energy is not.

Answer 1

The Correct Option is B

In an inelastic collision, kinetic energy is not conserved. Some of the initial kinetic energy is converted into other forms of energy such as heat, sound, and internal energy due to deformation. Thus, the kinetic energy after the collision is always less than the initial kinetic energy.
