Question

In most normal circumstances, which quantity of momentum doesn't change during collisions?

a) Force
b) Mass
c) Energy
d) Velocity

Answer 1

In most normal circumstances, mass doesn't change during collisions.

Step-by-step explanation:

The correct answer is b) Mass. In most normal circumstances, mass doesn't change during collisions. This is because mass is a measure of the amount of matter in an object and is independent of external forces acting on it. While force, energy, and velocity can change during collisions, mass remains constant.
