Physical Science Velocity and Acceleration Exam

Acceleration can be... (select all that apply)

• speeding up

• slowing down

• staying at constant speed

• changing directions

Velocity is different from speed because...

• Velocity is distance/time. Speed is displacement/time.

• Velocity is speed in a certain direction and can be positive or negative.

• Speed is velocity in a certain direction. Both can only be positive.

• Velocity is how much speed changes over time.

• The bicycle has constant velocity.

• The bicycle has constant speed.

• The bicycle is accelerating.

• The bicycle has 0 acceleration.

The image shows two cars with the same speed moving in different directions. What is true about the velocity of the cars?

• Each car has the same velocity because the speeds are the same.

• Each car has a different velocity because they are going in different directions.
