On what factors does the kinetic energy of a purely rotating body depend?

Explanation

To determine the factors on which the kinetic energy of a purely rotating body depends, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Kinetic Energy in Rotational Motion**:
- The kinetic energy (KE) of a rotating body is different from that of a translational motion. For translational motion, the kinetic energy is given by the formula:
\[
KE = \frac{1}{2} mv^2
