A cork floats a distance of 17.5 miles downriver after a period of 3 hours and 30 minutes.  What was its average speed?

• 7 mph
• 10 mph
• 9 mph
• 5 mph

What is speed?

• how far you go
• distance divided by time
• how fast you accelerate
• the change in the location of a object

What is velocity?

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

Can be measured in meters per second (m/s)

• Distance
• Time
• Speed
• Acceleration

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

• 0.7m/s2
• 7m/s2
• 14m/s2
• none of the above

The picture of the position vs. time graph shows an object that is...

• accelerating/speeding up
• moving at a constant speed 
• not moving 
• accelerating/slowing down.
