| Question |
Answer |
| force | A push or a pull |
| Friction | A force that oposes motion between two surfaces producing thermal energy |
| Gravity | The force of attraction between objects that is due to their masses. It can affect the position of an object or the direction of its motion. |
| Inertia | The tendency of all objects to resist any change |
| Motion | When an object changes position in relation to reference point over a period of time. |
| Net force | The force that results from combining all the forces exerted on an object |
| Newton | term or unit used to express force. |
| Speed | he rate at which an object moves; need distance and time to calculate |
| Velocity | The speed of an object in a particular direction. |
| Work | When a force causes an object to move in the direction of the force |
| Relative motion | When you compare one objects motion to another objects motion |
| Balanced force | A net force of zero |
| Unbalanced force | When the net force on an object isn't zero. It produces a change in motion. |
| Decelerate | a decrease in speed |
| Centripetal force | acceleration that occurs in circular motion. |
| Momentum | An object in motion has a hard time slowing down once its in motion. |
| reference point | A fixed point on Earth that can be used to describe a distance or direction. |
