Question

A) Rotational kinetic energy involves:

1. Velocity, mass, acceleration;
2. Velocity and mass only;
3. Angular velocity, moment of inertia, angular acceleration;
4. Angular velocity and moment of inertia only.

B) Any object’s moment of inertia depends on its:

2. Size and shape only;
3. Mass only;
4. Size, shape and mass.

C) For a given mass, the largest moment of inertia will be when it is shaped into a:

1. Ring;
2. Sphere;
3. Disk.

D) For a given mass, the largest moment of inertia will be when it is shaped into a:

1. Ring;
2. Sphere;
3. Disk.
