motion in one dimension

An increase or decrease in speed or change in direction is known as-

• acceleration

• time

• speed

• velocity

How fast one variable changes in relation to another variable on a graph is called-

• distance

• run

• slope

• rise

The distance an object moves per unit of time represents the-

• speed

• rate

• velocity

• acceleration

Average speed is calculated by-

• Total time/Total distance

• Total speed/ Total acceleration

• Total distance/Total time

• Total velocity/Total distance

What is motion measured relative to?

• time

• distance

• reference point

• rate

If two lines are on a motion graph, the line with the steeper_______________ indicates a greater speed.

• run

• slope

• rise

• distance

If two speedboats pass each other going opposite directions and each are moving 10Km/hour, they have the same-

• distance

• velocity

• length

• speed

If a runner is increasing her speed, would her initial speed be more or less than her final speed?

• It would be the same

• It would be more

• It would be less

• It would depend on what speed she started at and what speed she ended at

A horizontal line on a distance versus time graph represents an object that is-

• gaining speed

• slowing down

• not moving at all

• maintaining a constant speed

Velocity is determined by

• distance the object has traveled

• average speed of the object

• knowing the speed and direction of the object's motion

• instantaneous speed of the object
