Newton and His Three Laws

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 an example of Newton's First Law of Motion?

Back

A soccer ball sitting still on the ground will not move unless someone kicks it.

Front

What is an example of Newton's Second Law of Motion?

Back

If you push a shopping cart, it accelerates faster if it is empty than if it is full.

Front

What is an example of Newton's Third Law of Motion?

Back

When you jump off a small boat, the boat moves backward as you move forward.

Front

What is a force?

Back

A push or pull that can cause an object to move, stop, or change direction.

Front

What are friction and gravity examples of?

Back

Both are examples of forces that can affect the motion of objects.

Front

What happens to an object in motion if no forces act on it?

Back

It will continue moving at a constant velocity.

Front

What does the term 'acceleration' mean?

Back

The rate at which an object changes its velocity.
