Acceleration

The rate that a car's velocity changes is its

• speed

• force

• gravity

• acceleration

Acceleration is defined as the CHANGE in 

• time it takes for one place to move to another place. 
• velocity of an object.
• distance divided by the time interval 
• velocity divided by the time interval 

A negative acceleration means that your object is _____. 

• not accelerating
• not moving
• speeding up 
• slowing down 

A roller coaster accelerates from an initial speed of 6.0 m/s to a final speed of 70 m/s over 4 seconds. What's the acceleration?

• 24 m/s²

• 18 m/s²

• 16 m/s²

• 16 m/s

Acceleration only takes place when things speed up. 

• True
• False

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

• 0 m/s
• 40 m/s²
• -40 m/s²
• 40 m/s

A school bus drives 35 mph down the street and slows as it approaches the stop sign.  This is an example of..

• acceleration
• speed
• velocity
• force

A rightward-moving motorcycle increases its speed from 5.0 m/s to 25.0 m/s. Is the motorcycle accelerating?
