| Definition | Word |
|---|---|
| distance travelled per unit of time | speed |
| a point to compare motion against | frame of reference |
| the difference between speed and velocity is that velocity includes direction while speed_________ | doesn't |
| The Unit for speed | meters/sec |
| total distance divided by total time is | average speed |
| slope represents (speed or velocity) on a distance time graph | velocity |
| When most of the points on a distance time graph are close to the line of best fit it indicates __________ speed | constant |
| Acceleration is a rate of change in _______ | velocity |
| speed = ____ | d/t (distance divided by time) |
| acceleration= _______ | vf-vi/t (velocity final-velocity initial/ time) |
| A decrease in velocity is called ____________ | decleration |
| The units for acceleration are ________ | m/s/s |
| On a sketch tape the DOTS for a falling object should be _______ and ____ ___________. | Far away, get closer |
| An object moving at a constant speed would _________ | travel the same speed the whole way through |
| When an object at rest stays at rest it is called ________ | inertia |
