If the graph of speed versus time is a straight line, then the acceleration is constant/uniform. If the graph is curved or has a sharp corner, the acceleration is non-uniform, i.e. not constant. A uniform acceleration means the speed changes by fixed amount every unit of time, e.g. +3 m/s every second.
For uniform motion, the acceleration is zero. For non-uniform motion, the acceleration is something different than zero - at least, most of the time.
motion that is always constant [Either acceleration or deceleration that is called uniform motion......... motion that undergoes a change in velocity,either by changing speed or changing direction,,,,,that.s changes are called non uniform motion......
A roller coaster
As long as it has a non-zero velocity, it will have a non-zero momentum.
The colour green is a non example of acceleration.
"Uniform acceleration" means that acceleration doesn't change over time - usually for a fairly short time that you are considering. This is the case, for example, when an object drops under Earth's gravity - and air resistance is insignificant. "Non-uniform acceleration", of course, means that acceleration does change over time.
Freely falling body is a good example
Uniform (or constant) acceleration means that the acceleration doesn't change over time.
For uniform motion, the acceleration is zero. For non-uniform motion, the acceleration is something different than zero - at least, most of the time.

Uniform acceleration means that the acceleration doesn't change over the course of time (of the time considered for a certain problem, at least).
As long as it has a non-zero velocity, it will have a non-zero momentum.
Think of uniform as everything moving together. For example, in uniform circular motion describes the motion of a body traversing a circular path at constant speed. The distance of the body from the axis of rotation remains constant at all times. If the motion was non-uniform the distance of the body from the axis of rotation would vary.
We need the five example of uniform and non-uniform motion.
it cannot be same as the acc. is not zero
