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 |
