CW: Centripetal Force

What is a key characteristic of uniform circular motion?

• The tangential speed is constantly changing.

• The object moves in a straight line.

• The tangential speed remains constant.

• The centripetal acceleration is zero.

In uniform circular motion, what is the direction of the centripetal acceleration?

• Tangent to the circular path.

• Away from the center of the circle.

• Towards the center of the circle.

• Perpendicular to the plane of motion.

What happens if the centripetal force acting on an object in uniform circular motion is suddenly removed?

• The object will stop immediately.

• The object will move in a straight line tangent to its circular path.

• The object will spiral inward towards the center.

• The object will accelerate outwards from the center.

Which of the following is described as not being a real force, but rather a sensation due to inertia?

• Centripetal force

• Gravitational pull

• Frictional force

• Centrifugal force
