A man moving in a straight line with different speeds is an example of ___ motion.
The correct option is D non-uniform
When an object travels unequal distances in equal time intervals, it is known as non-uniform motion. In contrast, if it covers equal distances in equal time intervals, it is called uniform motion. In uniform motion, direction of motion does not change also.
When an object repeats its motion after some time, the motion is called periodic motion. In circular motion, the object moves in a circular path.
