Understanding Rotational Motion

What is the term used to describe the angle formed between a point on a rotating wheel and its reference orientation?

• Angular velocity

• Angular displacement

• Angular momentum

• Moment of inertia

How can the direction of angular velocity be determined?

• By measuring the speed of rotation

• Using the right-hand rule

• By observing the color of the wheel

• Using the left-hand rule

What happens when the angular velocity of a rotating object changes?

• The object stops rotating

• The mass of the object increases

• The object changes color

• Angular acceleration occurs

What is the force required to stop a rotating wheel called?

• Angular momentum

• Centripetal force

• Moment of inertia

• Gravitational force

What is angular momentum a product of?

• Distance and time

• Angular displacement and time

• Moment of inertia and angular velocity

• Mass and velocity
