Question

For what value of e is a collision partially elastic?

(a) 0 < e < 1

(b) 1

(c) e > 1

(d) 0

This question was addressed to me during an internship interview.

This is a very interesting question from Collision topic in chapter Work, Energy and Power of Physics – Class 11

Answer 1

The correct choice is (a) 0 < e < 1

The best I can explain: Partially elastic collision occurs when the value of e is less than one and more than zero. In this case the collision is neither perfectly elastic nor perfectly inelastic. Hence, we call it partially elastic collision.
