| the SI unit for length | meter |
|---|---|
| an object is said to be this if the distance from another object is changing | motion |
| a place or object used for comparison to determine if something is in motion | reference point |
| scientists all over the world use this same system of measurement so that they can communicate clearly | International System of Units |
| the distance an object travels per unit of time | speed |
| total distance traveled divided by the total time | average speed |
| the rate at which an object is moving at a given instatnt in time | instantaneous speed |
| speed in a given direction | velocity |
| the steepness of a line graph | slope |
| Earth's outer layer is made up of about a dozen of these | plates |
| Earth's plates moved slowly in various directions | theory of plate tectonics |
| the rate at which velocity changes | acceleration |
