Force and Motion

• a push or a pull

• force can change the motion of an object

• force can change the position of an object

• force can change the shape of an object

Motion is the act, process, or result of changing the position of an object from one place to another.

• a force that occurs when two objects touch or rub against each other

• a force of resistance that slows down or stops a moving object

• a force that creates heat

• a force that opposes motion (goes the opposite direction)

• a force that pulls all objects towards the Earth

• a force that acts on an object without the need for another object to touch it

Gravity is an invisible force that pulls two objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall.
