The force that one surface exerts on another surface when two objects rub against each other?

An object at rest will remain at rest unless acted upon by an unbalanced force. Likewise an object in motion will remain in motion unless acted upon by an unbalanced force.

Motion of an object depends on the objects mass and the net force applied to it.

The rate at which an objects speeds up, slows down or changes direction.

When two or more unequal forces act upon an object, resulting in a change or in motion or direction.
