WHATIS UNIFORM CIRCULAR MOTION
Uniform circular motion is when an object moves at a constant speed around a perfect circle. Perfect examples are very rare in the physical world, but approximations include a rider on a carousel, or a pendulum moving in a circle parallel to the ground. While planets and moons are often cited as examples of uniform circular motion, most planetary orbits are elliptical and fulfill neither the requirement that the speed always stay the same nor that motion must be circular.
