Question

can we take a circular path has a straight line when it comes to uniform and non uniform motion for example a car travels in a constant seed in circular path so whether it is uniform or non uniform

Answer 1

When a car travels in a constant speed in a circular path (actually path does not matter at all) it is said to be moving in a uniform motion . Because the motion of  an object depends on its speed, if speed is constant then the motion will be uniform and if not it will be called to be moving in a non uniform motion .
