Question

In an elastic collision between two objects, which quantities are conserved?
Options
A Only momentum
B Only kinetic energy
C Both momentum and kinetic energy
Correct Answer
D Neither momentum nor kinetic energy
Correct Answer

Option C is the correct answer.

Detailed Explanation

An elastic collision is defined as one in which both the total linear momentum and the total kinetic energy of the system are conserved.

Hint

This is the ideal, 'perfect bounce' type of collision, like billiard balls.
