Air resistance acted on in both gases and liquids.

A force that acts on objects that are not moving and is always opposing movement.

It is harder to start something moving, then to keep something moving that is already in motion (sliding friction).

When round objects roll across a flat floor and both the object and floor are bent slightly out of shape.

An object in motion tends to stay in motion but an object at rest tends to stay at rest.

Force = mass · acceleration

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