Forces and Motion
| Term | Definition |
|---|---|
| Gravity | a force that exists between any two objects that have mass |
| law of inertia | the tendency of an object to remain at rest or in motion |
| net force | the resulting force determined by combining all of the forces acting on an object |
| distance | the amount of space between one point and another |
| mass | the amount of matter in an object |
| newton's first law | An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. |
| newton's second law | The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. |
| newton's third law | For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. |
| acceleration due to gravity | the change in velocity caused by a gravitational force |
