Uniform Acceleration
Uniform acceleration is when an object changes its velocity by the same amount in every equal interval of time. This means that the object's acceleration remains constant over time.
- Example: A car accelerating at a constant rate of 2 m/s^2. In this case, the car's speed increases by 2 meters per second every second.
- In uniform acceleration, the velocity-time graph of the object will be a straight line, showing a constant increase or decrease in velocity.
- The formula to calculate velocity in uniform acceleration is v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time taken.

Non-Uniform Acceleration
Non-uniform acceleration occurs when an object's acceleration changes over time. This means that the object's velocity is not changing by the same amount in every equal interval of time.
- Example: A ball rolling down a hill where its acceleration is not constant due to factors like friction and air resistance.
- In non-uniform acceleration, the velocity-time graph will be curved, indicating a changing rate of acceleration.
- The formula to calculate velocity in non-uniform acceleration is more complex compared to uniform acceleration, as the acceleration is not constant.
In conclusion, understanding the difference between uniform and non-uniform acceleration is essential in analyzing the motion of objects in physics. Both types of acceleration play a crucial role in determining an object's velocity and motion in different scenarios.
