Kinematics of Circular <strong>Motion</strong>Example: Conical PendulumA metal bob at the end of a string is given a push so that it rotatesin a circular path in the horizontal planeFree body diagram to represent the forces:αl = length of stringm= mass of bobR = radius of circle followed+xTφmgαα+yThe centripetal force is given by sum of forces acting on the bob:T is tension, mg is weightacting towards the centre (i.e. in the +x-direction)
