What is tangential velocity also known as?

• Angular velocity

• Linear velocity

• Centripetal velocity

• Rotational velocity

What is a key term related to the force acting towards the center of a circular path?

• Tangential velocity

• Rotational speed

• Centripetal force

• Radius

What is the relationship between tangential velocity and centripetal force?

• As tangential velocity increases, centripetal force decreases.

• As tangential velocity increases, centripetal force remains constant.

• As tangential velocity increases, centripetal force increases by the square of the increase.

• As tangential velocity increases, centripetal force doubles.

What happens to centripetal force if the mass of an object is increased?

• It decreases.

• It remains the same.

• It increases.

• It becomes zero.
