Forces and Motion Flashcard

A force is a push or a pull that can change the motion of an object.

To pull an object means to apply a force that moves it closer to you.

Gravity is a force that pulls objects toward each other, like the Earth pulling us down.

Friction is a force that opposes motion between two surfaces that are in contact.

A force can change an object's speed, direction, or shape.

Pushing a door open is an example of a push.
