Define power in rotational motion?

Explanation

### Step-by-Step Solution:

1. **Understanding Power**:
Power in physics is defined as the rate at which work is done. In the context of rotational motion, we need to relate this to the concepts of torque and angular displacement.

2. **Work Done in Rotational Motion**:
In rotational motion, the work done (dW) can be expressed as the product of torque (τ) and the infinitesimal angular displacement (dθ). Mathematically, this is represented as:
\[
