The rotational energy of a body for a given angular speed depends on its:
Correct answer: D. Mass as well as distribution of mass about the axis of rotation
- A. Mass only
- B. Size only
- C. Mass and size
- D. Mass as well as distribution of mass about the axis of rotation
Explanation
The rotational energy of a body for a given angular speed depends on both its mass and the distribution of mass about the axis of rotation. This is because rotational energy is determined by the moment of inertia (I) of the object, which is a measure of how its mass is distributed with respect to the axis of rotation.The moment of inertia depends not only on the mass of the object but also on how that mass is distributed relative to the axis of rotation. Therefore, the correct option is D) Mass as well as distribution of mass about the axis of rotation.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
