The difference between speed and velocity is that velocity has a(n)

• magnitude

• value

• number

• direction

If I travel 30 meters in 10 seconds, what is my average speed?

• 300 m/s

• 3

• 3 m/s

• 0.3333 m/s

If you are traveling at 50 m/s, how far will you travel after 2 seconds

• 25 meters

• 50 meters

• 100

• 100 meters

What is acceleration?

• change in distance per time

• change in velocity per time

• change in displacement per time

• how fast you are going

The unit for acceleration is a
