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
