In an elastic collision?

I. Energy is conserved
II. Energy is decreased
III. Energy is increased
IV. Linear momentum conversed

A. I only
B. I and IV only
C. II only
D. III only

Correct Answer:

Option B – I and IV only

Explanation

In an inelastic collision, linear momentum is conserved and energy is decreased

Momentum and kinetic energy are conserved inelastic collision
