Term | Definition |
---|---|
position | an object's location in space |
motion | The change in an object's change in position over a specific amount of time. |
rate | A measure, quantity, or frequency usually measured in comparison with another object. |
linear motion | The movement of objects across lines |
displacement | The distance an object travels in a specific direction |
scalar quantity | The measure of distance alone |
vector quantity | something described by both a magnitude and a direction |
speed | When motion is described as distance per unit time |
equation for speed | Speed=distance/time |
Instantaneous rate | The speed of an object at a given time. |
average rate | The average rate of speed over an amount of time. |
velocity | the speed plus the direction an object is going. |
uniform motion | a constant rate of motion |
formula for velocity | velocity=final position-initial position/final time-initial time |
