Both acceleration s are similar. we can definitely it as a object changes it's velocity equally in equal interval of time then we can say that the body is in uniform or constant acceleration.

Constant Acceleration:

Constant acceleration is when an object changes its velocity at a steady rate over time, meaning that the acceleration remains the same throughout the entirety of the motion. This type of acceleration is usually represented by a straight line on a velocity-time graph. An example of constant acceleration is an object in free fall, where the acceleration due to gravity remains constant at 9.8 m/s².

Uniform Acceleration:

Uniform acceleration is when an object changes its velocity by the same amount over equal intervals of time. This means that the acceleration is constant but not necessarily the same value as time progresses. An example of uniform acceleration is a car accelerating from 0 to 60 mph in a certain amount of time where the acceleration is constant but not necessarily the same value over time.

Difference:

The main difference between constant acceleration and uniform acceleration is that in constant acceleration, the acceleration remains the same throughout the motion, while in uniform acceleration, the acceleration is constant but not necessarily the same value over time.

Another difference between the two is that constant acceleration is represented by a straight line on a velocity-time graph, whereas uniform acceleration is represented by a curved line on the same graph.

In summary, constant acceleration is a special case of uniform acceleration where the acceleration remains the same throughout the motion, while uniform acceleration is when the acceleration is constant but not necessarily the same value over time.
