Motion
| Question | Answer |
|---|---|
| position | an object's location in space |
| motion | the change in an object's position in a specific amount of time |
| rate | motion |
| linear motion | objects move along lines |
| displacement | the distance an object moves in a specific direction |
| scalar quantity | the distance alone; can be described using the magnitude (a number) |
| vector quantity | another name for displacement; can be described by both a magnitude and a direction |
| speed | distance (feet) per unit time (min) |
| equation for speed | speed = distance/time |
| instantaneous rate | present speed |
| average rate | miles per hour (mph) |
| velocity | the speed plus the direction along the path |
| uniform motion | motion with a constant rate |
| formula for velocity | velocity = final position - initial position/final time - initial time |
