If an object is spinning around on a string and the string was suddenly cut, the object would move in a

• curved path

• straight line

Why does an object experiencing uniform circular motion have an acceleration?

• because it ir changing speed

• because it is changing direction

• because it is moving n a straight line

• because it has mass

The _______________________ supplies the centripetal force requirement for the car to move in a horizontal circle. Without it, the car would turn its wheels but would not move in a circle (as is the case on an icy surface).

• friction force

• centrifugal force

• normal force

• applied force

What is the SI unit for circumference?

• meter
• pi
• inches
• kilometer

A ball is moving at constant speed around the circle. Which letter represents the acceleration of the ball?

• A

• B

• C

• D

• Nonsense. The ball can't be accelerating while moving at a constant speed.
