Define power in rotational motion?

Explanation

To define power in rotational motion, we can follow these steps:

### Step 1: Understand the Concept of Power
Power is defined as the rate at which work is done. This means that power measures how quickly work is being performed over time.

### Step 2: Express Power Mathematically
The mathematical expression for power (P) can be written as:
\[ P = \frac{dW}{dt} \]
