Question

difference between uniform motion and circular motion

Answer 1

a body is said to have a uniform motion if it travel equal distance in equal intervals of time no matter how small these intervals may be its called uniform motion.
movement of an object along the circumference of a circle or rotation along a circular path its called circular motion.

Answer 2

In uniform linear motion ,the speed and velocity are constant and acceleration is zero I.e.,the uniform linear motion is an unaccelerated motion ,while in a uniform circular motion the velocity is variable (although the speed is uniform ), so it is an accelerated motion.
