Front

What is Newton's First Law known as?

Back

The Law of Inertia.

Front

What does Newton's First Law state?

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?

Back

F=ma (Force equals mass times acceleration).

Front

What does Newton's Second Law imply about force and acceleration?

Back

When the force on an object is increased, the acceleration increases proportionally.

Front

What is Newton's Third Law?

Back

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

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that are not equal and opposite, resulting in a change in motion.

Front

Give an example of Newton's First Law in action.

Back

A book resting on a table stays at rest until someone pushes it.

Front

Give an example of Newton's Second Law in action.

Back

A car accelerates faster when more force is applied to the gas pedal.

Front

Give an example of Newton's Third Law in action.

Back

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