• speed includes direction, velocity does not

• velocity is always greater than speed

• velocity includes direction, speed does not

• there is no difference between speed and velocity

Motion is defined as a change in ____.

• time

• speed

• velocity

• position

The speed you read on the speedometer in your car is ____.

• instantaneous speed

• constant speed

• average speed

• velocity

3 m/s north is an example of a(n) ____.

• speed

• velocity

• position

• Acceleration

Because velocity includes both size and direction, it is referred to as a ______ quantity.

• displacement

• vector

• scalar

• maximum

Acceleration is defined as a change in what over a period of time?

• speed

• velocity

• distance

• Displacement

What can be found by calculating the slope on a distance-time graph?

• average speed

• displacement

• velocity

• Acceleration

The SI unit for acceleration is

• ft/s

• m/s

• m/s²

• km/min²

This variable is the independent variable on both a distance-time graph and a speed-time graph, and will always be plotted on the x-axis:

• distance

• speed

• time

• Slope
