The colour green is a non example of acceleration.
something standing still, or an object not in motion, anything that is not in motion.
it is actually a non example of acceleration is when it is not moving /not accelerating and it is like when a car with its own cruise control set
slowly
calm water
A roller coaster
For example, an object thrown upwards, when it is at its highest point. This situation is only possible for an instant - if the acceleration is non-zero, the velocity changes, and can therefore not remain at zero.
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.
Average acceleration will be equal to instantaneous acceleration when an object has an uniform acceleration throughout its motion. Example : A car accelerating at 1m/s2 uniformly in a straight line.
Freely falling body is a good example
"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.

No. ME isn't capable of understanding this. Feisty with Beryl, OTOH....

Acceleration due to gravity is a uniform acceleration of 9.8m/s2.
Uniform (or constant) acceleration means that the acceleration doesn't change over time.
Unnecessary acceleration uses more fuel
Average acceleration will be equal to instantaneous acceleration when an object has an uniform acceleration throughout its motion. Example : A car accelerating at 1m/s2 uniformly in a straight line.
