Newton's Laws of Motion

Front

What is Newton's First Law of Motion?

Back

An object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an unbalanced 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 = ma)

Front

What is Newton's Third Law of Motion?

Back

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

Front

How many laws of motion did Newton propose?

Back

Three.

Front

What does inertia mean?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

Give an example of Newton's First Law of Motion.

Back

A book resting on a table will not move unless someone pushes it.

Front

What happens when two forces of equal strength act in opposite directions?

Back

The object will not move at all.

Front

What is the formula for Newton's Second Law of Motion?

Back

F = ma (Force equals mass times acceleration).

Front

If a skateboarder pushes the ground backwards, what happens to the skateboard?

Back

The skateboard moves forward due to Newton's Third Law of Motion.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its motion.
