Since your question isn't clear. I will assume that your question is : The difference between uniform and non - uniform motion. OKAY?
Explanation:
Uniform motion : When an object travels equal distance in equal period of time it is said to be in uniform motion. It can be measured continently. ex. Swinging of pendulum
Non-Uniform Motion : When an object travels unequal distance in unequal periods of time it is said to be in non uniform motion. It is harder or impossible to measure. ex. A bike taking turns and going at variable speed every time.
If there's a mistake then please being it to my concern. Hope it helps
