What is speed?

• how far you go
• how much distance is covered over a period of time
• how fast you accelerate
• the change in the location of a object

A runner races in the 100 meter dash. It takes her 10 seconds to finish. What is her speed?

• 10 m/s

• 1000 m/s

• 100 seconds

• 10 seconds

What is velocity?

• the quickness of an object
• the location of an object
• acceleration
• speed in a specific direction

A car accelerates from rest to 70 m/s in 10 seconds. What is the acceleration?

• 0.7m/s²

• 7m/s²

• 14m/s²

• none of the above

Acceleration has both a magnitude (number) and a direction (positive or negative). Acceleration is therefore a...

• scalar

• vector

• frame of reference

• measure of time

A car slows from 70 m/s to 50 m/s in 10 seconds. What is the acceleration?

• 0.2m/s²

• 2m/s²

• -2m/s²

• -0.2m/s²

A drag racer accelerated from 0 m/s to 200 m/s in 5 s.  What was the acceleration?
