Fill in the Blank

How many Newton's Laws exist?

Newton's First Law says:

An object at rest stays at rest and an object in motion stays in motion unless acted on by an outside force.

This means something at rest stays there forever until something moves it and

An object in motion will stay in motion forever until something or someone slows them down.

Multiple Choice

An object in _____ stays in motion

• motion

• rest

• inertia

• force

Fill in the Blank

An object at ____ stays at rest

Newton's Second Law:

Force = Mass X Acceleration

This means if something has more mass, it will take more force to move it.

Fill in the Blank

Force = ____ X Acceleration

Multiple Choice

Find the force of an object if the mass is 10 kg and the acceleration is 2 m/s2?

• 20 N

• 10 N

• 12 N

• 8 N

Newton's Third Law:

For every action there is an equal and opposite reaction.

This means when one thing happens, another happens because of it.
