Newton’s Laws of Motion

Front

The water pushes back.

Front

Does gravity attract all objects towards one another?

Back

True

Front

What is the measurement of force?

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 term for a tendency to do nothing or remain at rest?

Back

Inertia.

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 Newton's 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 (F=ma).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton.

Front

What is inertia?

Back
