Since the body describes circular motion, its distance from the axis of rotation remains constant at all times. So, the centripetal force is the force acting on a body over a circular path. Here, the velocity and speed remains constant. Solution: For uniform circular motion, the magnitude of velocity remains unchanged but due to change in direction the velocity vector changes. What is Circular Motion When an object moves in a circle, it is called Circular Motion Example An athlete taking a round of a circular park What is Uniform Circular Motion If an object moves in a circular path with uniform speed, it is called Uniform Circular Motion Examples Motion of Moon(Moon Moving around the earth) As acceleration is perpendicular to the velocity, it only changes the direction of velocity, and the magnitude remains unchanged. Considering the uniform circular motion, the acceleration is: a=acceleration, r=radius, v=velocity of the object, ω=angular speed. When they are moving in a circular arc they havecentripetal acceleration. The shadow undergoes simple harmonic motion. This is otherwise called as centripetal acceleration, and the force that acts towards the center is known as centripetal force. o Uniform circular motion. There are two kinds of circular motion that can act upon a body in motion: In the case of uniform circular motion, the angular speed & acceleration remains constant, whereas the velocity differs. Give some Application of Uniform Circular Motion. For Example: You have a ball attached to a string, and you move it uniformly over a circular motion; then, two interesting observations can be made. Here, uniform circular motion is a particular kind of circular motion where the motion of the body follows a circular path at a constant/uniform speed. There is a small hot spot in the top-left corner. Drying clothes in spin dryer- clothes are placed in a perforated drum rotated at high speed, water is expelled through the holes and this makes the clothes dry. Explanation. 10 meters/second means each 1 second, particle’s displacement = 10 meters. On signing up you are confirming that you have read and agree to 5. 1. Key Terms .
