Can a particle have a constant velocity and varying speed ?

Explanation

To answer the question, "Can a particle have a constant velocity and varying speed?", we can analyze the definitions of velocity and speed step by step.

### Step 1: Understand the Definitions
- **Velocity** is defined as the rate of change of displacement with respect to time. Mathematically, it is given by:
\[ \text{Velocity} = \frac{\text{Displacement}}{\text{Time}} \]
- **Speed** is defined as the rate of change of distance with respect to time. Mathematically, it is given by:
