Question

Identify the wrong statement.

• A. A body can have momentum without energy
• B. A body can have energy without momentum
• C. The momentum is conserved in an elastic collision
• D. Kinetic energy is not conserved in an inelastic collision

Answer 1

Answer: (A)

If a body has momentum, it must have kinetic energy whereas if the energy is totally potential, it need not have momentum.
The momentum is conserved in all types of collision and kinetic energy is not conserved in an inelastic collision.
