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.
1. You will have a uniform acceleration of about 9.8 meters/second2 when an object is in free fall near the Earth's surface - for example, when you drop an object, and air resistance can be ignored. 2. Any situation where the force is constant. 3. Uniform acceleration is often assumed for simplicity, for example, when accelerating a car.
As long as it has a non-zero velocity, it will have a non-zero momentum.
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......
"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.
Acceleration due to gravity is a uniform acceleration of 9.8m/s2.
For uniform motion, the acceleration is zero. For non-uniform motion, the acceleration is something different than zero - at least, most of the 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).
There are several formulae that involve uniform acceleration. For example, the definition of uniform acceleration:dv/dt = c or: a = c (where "c" is some constant).

No. Acceleration is towards the center of the movement, in other words, the acceleration vector changes all the time.
