Speed |
the rate of change of the position of an object; the amount of distance covered in a given period of time; can be calculated using the formula: v = d / t |
|
|
Average speed |
the total distance traveled divided by total time of travel |
|
|
Time-distance graph |
A representation of how both speed and distance change with time; the slope of the graph can be used to describe the speed of an object |
|
|
Force |
a push or pull |
|
|
