What do you mean by angular displacement ? Is it a scalar or vector ?

Explanation

### Step-by-Step Solution:

1. **Definition of Angular Displacement**:
- Angular displacement refers to the change in the angular position of an object moving along a circular path. It is analogous to linear displacement, which measures the change in position along a straight line.
- Mathematically, angular displacement (Δθ) can be expressed as:
\[ \Delta \theta = \theta_2 - \theta_1 \]
