The circular motion is a motion in which the distance of a particle (radius) moving in a plane from a fixed point (centre) remains constant then its motion. Designed by the teachers at SAVE MY EXAMS for the CIE IGCSE Physics 0625 / 0972 syllabus. It can be classified into two types: uniform with constant speed and constant angular rotation rate or non-uniform with changing rotation rate. To understand the circular orbits of satellites and planets as another case of circular motion. This can be called spinning motion. It is a special kind of two-dimensional motion in which the particle's position vector always lies on the circumference of a circle. If the magnitude of the velocity of the body in circular motion is n constant, then it is called non-uniform circular motion.

Uniform Circular Motion For an object to move along a curved path, the direction of its velocity must change. Newton's Laws of Motion 1. When a body performs circular motion with constant speed it is called uniform circular motion. This can be called spinning motion. The gravitational force from the earth makes the satellites stay in the circular orbit around the earth. A body is said to be in circular motion if it moves in a manner that the distance from a particular fixed point always remains same. Circular Motion Notes Overview. Google Classroom Facebook Twitter. Circular Motion Notes Class 11th – IIT JEE | By eSaral. * constantly accelerating a = v Δ t and v = Δ d Δ tso a change in direction OR a change in speed will result in acceleration. The centripetal acceleration has to be provided by some other force (tension, friction, normal force) in order for circular motion to occur.

THE DYNAMICS OF CIRCULAR MOTION Centripetal Force When a particle or a body moves with a uniform speed v on a circular path of radius r, it has a centripetal acceleration […] The speed of a body in a uniform circular motion remains constant but the velocity changes continuously since, the direction of motion is changing continuously. An object remains at a constant velocity unless acted on by a force. The intense circular motion of the wind around the eye of a hurricane that occurs on the surface of the ocean generates a vertical circular motion in the oceanic waters (Resio and Westerink, 2008). If the axis of rotation is outside the object, the object is revolving. Note that centripetal force is the name given to the resultant force: it is not a separate force in the free-body diagram. for circular motion: (80 kg)(4 m/s) 2 600 N. r rr= 2.13 m = 2.13 m.
