The Horizontal Circle Simulation provides the learner with an interactive, variable-rich environment for exploring the motion of an object in a horizontal circle. When an external force is applied to a body of constant mass the force produces an acceleration, which is directly proportional to the force and inversely proportional to the mass of the body. If at any time (t), the body is at the angular position θ, the forces acting are: tension (T) in the string along the radius (r) towards the centre and the weight (w) of the body, i. F. We often consider the motion of an object around a circle of fixed radius, R. 4: Circular motion. So i have a concept question. Unless this force is present, no object can execute a pure circular motion, because in absence of a force, a body moves uninterrupted along a straight line (Newton's first law).
