Laws of Motion (Newton)

Front

What is Newton's First Law of Motion?

Back

An object will stay at rest or in motion until acted upon by another force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied. (F = m × a)

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is force?

Back

A push or pull on an object.

Front

What is mass?

Back

The amount of matter in an object, usually measured in kilograms or pounds.

Front

What is acceleration?

Back

The rate at which an object changes its velocity.

Front

If a ball has a mass of 10 kg and an acceleration of 10 m/s², what is the force?

Back

100 N (Force = mass × acceleration)

Front

Why does a chair not collapse when a child sits on it?

Back

The chair exerts the same amount of force back up on the child.

Front

What happens to the acceleration of an object if more force is applied?

Back

The acceleration will increase.

Front

What is an example of an action-reaction pair?

Back

When you push against a wall, the wall pushes back with equal force.
