If something is traveling at a constant velocity, what is the acceleration?

• Positive

• Negative

• Zero

• Not enough information

Answer explanation

A constant velocity means the velocity does not change. Therefore, if there is not change in velocity, there is no acceleration.

Describe the motion of the object.

• Constant speed

• Moving in a negative direction

• Moving in a positive direction

• Moving at a constant speed

• Speeding up
