Front

An object at rest will stay at rest and an object in motion will stay in motion unless acted on by a force, is which one of Newton's Laws of Motion? Options: 4th Law of Motion, 1st Law of Motion, 3rd Law of Motion, 2nd Law of Motion

Back

1st Law of Motion

Front

What is an elastic collision?

Back

An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies remains the same.

Front

What is an inelastic collision?

Back

When two objects collide, becoming stuck together and internal kinetic energy is lost (but not really lost, it transfers to different forms of energy)

Front

Do both objects have velocities acting in the same direction?

Back

No
