Acceleration

You ride your bike in a straight line at a constant speed of 10 km/h.

• Acceleration occurred because speed increased.

• Acceleration did not occur because neither speed nor direction changed.

• Acceleration occurred because you changed directions.

• Acceleration occurred because speed decreased.

Identify the following scenario as Speed, Velocity, or Acceleration: I was stopped at the intersection but when the light turned green, I sped away as fast as possible.

• Speed

• Velocity

• Acceleration
