Changes in Force and Motion
| Term | Definition |
|---|---|
| Resting Position | Refers to an object remaining in the same spot relative to another object. |
| Motion | The change in an object's position with respect to time and in comparison with the position of other objects used as reference points. |
| Direction | the path that an object is moving or facing. |
| Speed | The rate of change of position (or distance traveled) with respect to time; units in which speed is measured are expressed as distance per time (example: meters per second). |
| Distance-Time Graph | This type of graph illustrates changes in motion. Time is graphed on the ex-axis and distance is graphed on the y-axis |
| Line Graph | A graph in which the data are represented by points connected by one or more lines. |
| X-Axis | The horizontal line with labels on a coordinate grid; time is represented on the x-axis. |
| Y-Axis | The vertical line with labels on a coordinate grid; distance is represented on the y-axis. |
| Average Speed | Average speed is calculated by dividing the total distance an object traveled by the total time it took the object to travel the distance (s=d/t). Speed describes the rate of movement. |
| Force | a push or pull that can change the motion of an object, measured with a spring scale in Newton (N) units. |
| Balanced Forces | Forces on an object that do not change the motion of the object. |
| Unbalanced Forces | Forces on an object that cause that cause change in the motion of the object. |
| Potential Energy | Energy that is stored in a system or object. |
| Kinetic Energy | Energy of motion. |
