Rotational Motion Cheat Sheet Tangential Speed Linear Speed Linear speed and tangential speed gives the same meaning for circular motion. Note however that these two motions are i. Our topic for today is a different type of motion called vertical circular motion. The motion is called uniform circular motion when the particle is moving along a circular path possessing a constant speed. If we examine the figure below it is evident that there are two solutions to the problem We arrive at the first solution by using a pocket calculator and keying This is the source of the centripetal force that allows the bob to follow its circular trajectory. Note that the centripetal force is proportional to the square of the velocity implying that a doubling of speed will require four times the centripetal force to keep the motion in a circle. Apr 12 2015 2. In the free body diagram below what is the balancing force in the question mark The second equation states that the Tension in the rope at bottom of swing will be equal to the sum of the Centripetal Force and weight of person swinging on rope.
