Motion

When one object's distance from another object is changing

Distance

How far one point is from another

Time

The exact moment or how long something takes to do

Speed

The distance an object travels in a specific amount of time

Average Speed

The overall rate of speed that an object moves - calculation is total distance divided by total time

Acceleration

The rate at which speed (or velocity) changes

Negative Acceleration

When speed decreases

Proportional Relationship

A relationship in which both variables either increase or decrease at one time

Inverse Relationship

A relationship in which one variable decreases when another variable increases.

Slope

The steepness of a line on a graph; When you graph distance v. time, slope tells us the speed of an object
