Motion

Speed equals distance divided by

• velocity

• time

• motion

• acceleration

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

The steepness of a line on a graph is called the-

• horizontal line

• vertical axis

• slope

• rise

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

An object changing direction is an example of-

• speed

• velocity

• acceleration

• ambivalence

• accelerates

• decelerates

• spins around in circles

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

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

• distance

• velocity

• length

• speed

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

• run

• slope

• rise

• distance

What is motion measured relative to?

• time

• distance

• reference point

• rate
