What is gravity?

Back

A non-contact force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What is air resistance?

Back

A contact force that opposes the motion of an object through the air.

Front

What is normal force?

Back

The support force exerted by a surface perpendicular to the object resting on it.

Front

What is friction?

Back

A contact force that opposes the motion of an object when it is in contact with another surface.

Front

What is tension?

Back

A contact force that is transmitted through a string, rope, or wire when it is pulled tight.
