Force and Motion
| Term | Definition |
|---|---|
| Position Speed The distance an object moves in a unit of time. Force A push or pull on an object. Newton’s 2nd Law The acceleration of an object decreases as an objects mass increases, and that the accel | The location of an object. Its distance and direction from a reference point. |
| Reference Point | Is a starting point used to locate another place or thing. |
| Motion | When there is a change in position of an object with respect of a reference point. |
| Displacement | The difference between a starting position and the final position. |
| Direction | Is the line, or path along which something is moving, pointing, or aiming. |
| Distance-Time Graph | Used to represent the speed of an object. |
| Average Speed | "The result of the total distance divided by the by the total time taken." |
| Newton’s 1st Law of Motion | If the forces acting on an object are balanced, the motion of the object does not change. |
| Newton’s 3rd Law of Motion | "When one object exerts a force on a second, the second one exerts a force on the first that is equal in magnitude and opposite in direction."(It is often called the Law of Action and Reaction) |
| Balanced Force | Something that will cause no change in the speed of an object. |
| Unbalanced Force | Not equal and they also cause the motion of an object to change the speed or direction that is moving. |
| Friction | A contact force that opposes the motion of two surfaces that are touching. |
| Gravity | A noncontact force that every object exerts on every other object because of its mass. |
| Mass | The amount of matter in an object. |
