What is velocity?

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

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

• 10 m/s
• 1000 m/s
• 100 seconds
• 10 seconds

Total distance divided by total time is

• average speed
• constant speed
• instantaneous speed
• acceleration

The correct equation to calculate speed is

• distance/time
• time/distance
• distance x time
• distance/time²
