Back

Gravitational

Front

What is Newton's third law?

Back

Front

Why would a person weigh less on the Moon than on Earth?

Back

The Moon has less mass and therefore less gravity.

Front

What is the formula for force?

Back

Force = mass x acceleration

Front

What is the 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 second law of motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the third law of motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is gravity?

Back

A force that attracts two bodies towards each other.

Front

What is mass?

Back
