Differentiate between uniform acceleration and variable acceleration.

Explanation

### Step-by-Step Text Solution

1. **Definition of Acceleration**:
- Acceleration is defined as the rate of change of velocity with respect to time. Mathematically, it is expressed as \( a = \frac{dv}{dt} \), where \( dv \) is the change in velocity and \( dt \) is the change in time.

2. **Uniform Acceleration**:
- In the case of uniform acceleration, the change in velocity occurs at a constant rate. This means that for equal time intervals, the change in velocity is the same.
- For example, if a ball is dropped from a height, it experiences a uniform acceleration due to gravity, which is approximately \( 9.8 \, \text{m/s}^2 \). This acceleration remains constant in both magnitude and direction throughout the motion.
