Can a body have acceleration without having velocity?

Explanation

To determine whether a body can have acceleration without having velocity, we can analyze the concept through two examples: motion under gravity and simple harmonic motion (SHM).

### Step-by-Step Solution:

1. **Understanding Acceleration and Velocity**:
- Acceleration is defined as the rate of change of velocity with respect to time. It can exist even when the velocity is zero.

2. **Example 1: Motion Under Gravity**:
