5What is rolling friction?
- AWhen round objects roll across a flat floor and both the object and floor are bent slightly out of shape.
- BAir resistance acted on in both gases and liquids.
- CA force that acts on objects that are NOT MOVING and is ALWAYS OPPOSING movement
- DIt is harder to start something moving, then to keep something moving that is already in motion (sliding friction).

12What does Newton's 3rd Law state?
- AFor every action, there is an equal but opposite reaction.
- BForce = mass · acceleration
- CAn object in motion tends to stay in motion but an object at rest tends to stay at rest.
13What does Newton's 2nd Law state?
- AAn object in motion tends to stay in motion but an object at rest tends to stay at rest.
- BForce = mass · acceleration
- CFor every action, there is an equal but opposite reaction.
