Question

1. What is the most accurate statement concerning angular displacement?

The angle must be measured in radians.

Angular displacement must be expressed in radians for rotational kinematic equations.

Angular displacement is the ratio of the circular radius to the arc length subtended by the angle theta.

Angular displacement and linear displacement are both tangent to the circle anywhere on the path.

Angular displacement protractors are a special measuring tool used to measure angular displacement in the physics lab.

2. What is the most accurate statement concerning angular momentum?

When an outside torque acts on a system, both momentum and angular momentum are conserved.

Like rotational kinetic energy, angular momentum is a vector quantity that is conserved in all collisions.

More massive objects will always process more angular momentum than less massive objects.

Angular momentum is the product of moment of inertia and angular velocity.

Angular momentum is the product of moment of inertia and angular acceleration.

3. What is the most accurate statement concerning rotational work?

Rotational work and rotational mechanical energy represent the same quantity because they have the same units.

Rotational work on a system causes a change in the energy of the system.

An applied torque on an object always causes work to be done on the object.

Rotational work is a vector quantity found by multiplying two vector quantities, torque and angular displacement.

Rotational work is a positive scalar quantity that represents torque multiplied by displacement.

4. What is the most accurate statement concerning angular velocity?

Angular velocity, omega, is the change in displacement divided by the time interval over which that change occurred.

The SI unit for angular velocity is degree/s.

Angular velocity, omega, is the change in angular displacement divided by the time interval over which that change occurred.

Angular velocity must be negative for objects rotating in a clockwise direction.

Angular velocity must be negative for objects rotating in a counterclockwise direction.
