✔ 最佳答案
Since Velocity. v = u + at. Uniform acceleration means that the velocity will increase or decrease continuously(due to the sign of the acceleration ) Also the velocity changes by the same amount in every second.

non uniform acceleration
The slope of a v/t graph represents acceleration.

Sorry﹐答漏Uniform Acceleration = Constant acceleration

Uniform Acceleration & constant acceleration are the same.
The velocity is uniformly accelerated.
