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

Acceleration only takes place when things speed up. 

• True
• False

Suppose you take a trip that covers 180km in 3 hours. Your average speed is...

• 30km/hr
• 360km/hr
• 180 km/hr
• 60km/hr

What is velocity?

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

Which is correct?

• speed = distance x time
• speed = speed divided time
• speed = Distance divide time
• Speed = time x speed

Does the speedometer of a car read average speed or instantaneous speed?

• average speed
• instantaneous speed

When a car goes around a corner at 20 mph, why do we say it  accelerates?

• The car is accelerating because of the velocity is constant
• The car accelerates because it's going 20 mph
• Cars always accelerate when they are in motion
• The car is accelerating because it's changing direction

When one object is travelling with a constant velocity, its acceleration will be 

• decreasing
• increasing
• constant
• zero

An aeroplance is flying with decreasing acceleration, hence its velocity is 

• increasing 
• decreasing
• constant

A student starts cycling at a speed of 12 m/s in 6 seconds. The distance travelled by him is

• 18 m

• 36 m

• 54 m

• 72 m
