If you slow down on your bicycle, you accelerate.

• True

• False

Speeding up, slowing down and changing the direction of your bicycle are all examples of acceleration.

• True

• False

You ride your bike around the block at a constant speed of 11 km/h. Acceleration occurred because:

• Speed increased

• You changed direction

• Speed decreased

• Acceleration didn't occur

• Velocity

• Vector

• Speed

• Acceleration
