Motion
| Term | Definition |
|---|---|
| Displacement | Distance from the origin to our destination traveling in a straight path. The direction from the starting point AND the length of a straight line from the starting point to the ending point. |
| Distance | Distance from the origin to a destination. The length of a path between two points. |
| Velocity | My speed and direction. (distance divided by time + direction) |
| Speed | How fast I am moving.(Distance divided by time) |
| Acceleration | The rate at which velocity changes. Basically, the rate at which something changes its speed - faster or slower. (change in velocity/time) |
| Magnitude | Size, length, or amount. Ex. We measure the length of a vector (arrow). |
| Vector | A quantity that has magnitude and direction. (arrow) Used to help us measure displacement, velocity, and acceleration. |
| Direction | Which way I am moving. |
| Reference Point | The point from which all motion will be referenced. |
| Motion | Occurs when an object changes its position. |
| Constant Acceleration | The velocity is changing by a constant(the same)amount each second. |
| Constant Velocity | The distance traveled in a certain direction is changing by a constant (the same) amount each second. |
| Zero Acceleration | There is zero motion or there is no change in velocity (you are travelling at a constant velocity). |
