# Speed, Velocity, and Acceleration

## Speed, Velocity, and Acceleration Answer Key

1.

Average speed equals:

- Distance/ Time
- Time/ Distance
- Distance + Time

2.

Velocity is the:

- measure of time and distance
- measure of space and time
- measure of speed that is constant
- measure of speed in a certain direction

3.

What information is required in order to measure speed?

- time and distance
- velocity and time
- distance and velocity
- momentum and time

4.

This describes how far an object moves during a certain amount of time.

- velocity
- magnitude
- average speed

5.

Acceleration refers to

- increasing speed
- decreasing speed
- changing direction
- all of the above

6.

An object will not change its velocity if a force acts upon it.

- True
- False

7.

What does a car's speedometer measure?

- Speed
- Velocity
- Both

8.

The slope of a distance-time graph correlates to:

- acceleration
- time
- distance
- velocity

9.

Calculate the average speed of a bicycle that travels 100m in 20 s.

- 5m/s

10.

If you speed up from rest to 12 m/s in 3 seconds, what is your acceleration?

- 4m
- 4 m/s/s
