• Speed = distance/time

• Speed = distance x time

• Speed = time x distance

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

• The car is accelerating because 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

Calculate the average speed (in m/s) if a cheetah runs 180 metres in 10 seconds.

• 198 m/s

• 170 m/s

• 12 m/s

• 18 m/s

Of the following, which is a vector?

• Mass
• Time
• Speed
• Velocity

Acceleration is defined as the "change in..."

• the time it takes to move from one place to another.

• velocity of an object.

• distance, divided by the time taken.

• velocity, divided by the time taken.

Acceleration only takes place when things speed up. 

• True
• False

• A car moving away from green traffic lights.

• A car approaching a red traffic light.

• A car with the cruise control set at 80 km/h.

• A car turning a curve at a constant speed.
