In an inelastic collision?

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

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

Correct Answer:

Option B – II and IV only

Explanation

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

Momentum and kinetic energy are conserved in elastic collision
