What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is Newton's first law of motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the role of friction in motion?

Back

Friction opposes the motion of an object, slowing it down or stopping it.

Front

How does gravity vary with distance from the Earth?

Back

Gravity decreases as the distance from the Earth's center increases.
