Forces in Motion
| Term | Definition |

| Force | A push or pull |
| Position | The location of an object |
| Friction | A contact force that opposes the motion of an object |
| Motion | A change in the position of an object |
| Magnetism | A non-contact force that pulls objects containing iron |
| Speed | The rate of which an object changes position |
| Gravity | A non-contact force that pulls objects towards one another |
| What is motion? (4) | Change of position Position is location of an object or its place Speed is rate an object changes its position If the motion of an object has a regular pattern, you may be able to predict the future motion |
| How does force affect motion? (3) | It is a push or pull Amount of force used affects the motion Mass, friction, and magnetism affect an object's motion |
| What is gravity? (2) | Non-contact force that pulls objects towards one another The pull of gravity on an object gives the object its weight |
| Variable speed | Speed that changes as it moves |
| Constant speed | Something that does not change how fast or slow it moves |
