Definition circular motion |
| Answer» Uniform Circular MotionThis motion refers to the circular motion if the magnitude of the velocity of the particle in circular motion remains constant. The non-uniform circular motion refers to the circular motion when the magnitude of the velocity of the object is\xa0not constant. Another special kind of circular motion is when an object rotates around itself also known by spinning motion. | |
