There are some ways objects in motion are affected. _Force_, or pushes and pulls, affect the motion of an object. _Gravity_ is a force that pulls objects down to Earth. _Friction_ is a force that slows things down or can even make them stop. Did you know acceleration means more than the increase of an object’s speed? It also describes an object that is slowing down or changing _velocity_. Since acceleration is a change in speed or direction, that means, _acceleration_ is a change in velocity.

Explanation:

This is kind of self explanatory, since these are just the definitions, so instead I'll give you examples so you can further understand these definitions.

FORCE: When you push a cart, and move a book from one desk to another.

GRAVITY: The force that causes a ball you throw in the air to come down again (notice how I mentioned force, which is why gravity is a type of force)

FRICTION: If you were walking in the park, you wouldn't be able to stop without friction.
