Answer (1 of 4): The KE of a mass in circular motion is different from the kinetic energy of a rotating body*. Part B - Recall what you learned in vertical circular motion. Circular motion occurs when a force acts tangentially to the direction of motion of a body at all times. The energy of the system is oscillating back and forth between kinetic energy and potential energy. However, since it is a multiple-choice question, we can also attempt to eliminate the wrong answers. Questions pertain to the application of Newton's three laws of motion and universal gravitation to situations involving the motion of objects in circles and orbiting objects. Because the speed of a circular orbit is constant, the period is simply the circumference divided by the velocity: The specific energy of the circular orbit is negative. If the object is constrained to move in a circle and the total tangential force acting on the object is zero, F θ total = 0 then (Newton's Second Law), the tangential acceleration is zero, (6.4.1) a θ = 0.
