Front

What is a force?

Back

A force is a push or pull acting on an object.

Front

True or False: Friction and gravity are both examples of a force.

Back

True

Front

What is net force?

Back

Net force is the sum of all forces acting on an object.

Front

How do you find the net force when two forces are acting in the same direction?

Back

Add the magnitudes of the forces.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the normal force?

Back

The normal force is the support force exerted upon an object that is in contact with a stable surface.

Front

If two forces of 15 N are acting to the right, what is the net force?

Back

30 N to the right.

Front

What happens to the net force if two equal forces act in opposite directions?

Back

The net force is zero.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What is the relationship between mass and net force?

Back

Net force is equal to mass times acceleration (F = ma).
