speed

how fast something moves in a period of time.

average speed

The average distance traveled divided by the time it takes to travel that distance.

instantaneous speed

velocity

The speed and direction an object is moving, measured relative to a reference point.

nonlinear graph

curve that connects data points

linear graph

a graph that uses lines to represent data.

constant acceleration

steady change of velocity.

free fall

movement of an object toward earth solely because of gravity.

acceleration

can be described as changes in speed, changes in direction, or changes in both.
