Learning Goal: Understand how to find the equation of motion of a particle undergoing uniform circular motion. Consider a particle--the small red block in the figure--that is constrained to move in a circle of radius R. We can specify its position solely by f(t), the angle that the vector from the origin to the block makes with our chosen reference axis at time t. Following the standard conventions we measure 8(t) in the counterclockwise direction from the positive x axis.
