Force and Motion
*7.7ABCD Force & Motion
| Term | Definition |
|---|---|
| displacement | length of a straight line between two points |
| distance | total length of the path actually taken from Point A to Point B |
| speed | how fast an object is moving at a specific moment in time; s=d/t |
| velocity | speed in a specific direction |
| uniform motion | motion of an object with a velocity that does not change |
| slope | Steepness of a graph at a given point |
| force | a push or a pull |
| inertia | tendency of an object to remain stationary or to remain in motion |
| unbalanced force | a force on an object that is not canceled by other forces |
| balanced forces | forces of equal magnitude but in opposite directions acting on the same object |
| magnitude | size or importance |
| average speed | total distance divided by total time taken over an entire journey |
| distance-time graph | line graph used to show the speed of a moving object |
| acceleration | rate of change of velocity |
| constant speed | moving at a steady rate over time |
| motion | object's change in position relative to a reference point |
| origin | fixed point from which motion begins |
| x-axis | horizontal line on a graph |
| y-axis | vertical axis on a graph |
