WebIf an object is moving in uniform circular motion at speed v and radius r, you can find the magnitude of the centripetal acceleration with the following equation: Because force equals mass times acceleration, F = ma, and because centripetal acceleration is equal to v2 / r, … If a force is allowed to act through a distance, it is doing mechanical work. Similarly, if torque is allowed to act through an angular displacement, it is doing work. Mathematically, for rotation about a fixed axis through the center of mass, the work W can be expressed as where τ is torque, and θ1 and θ2 represent (respectively) the initial and final angular positions of the body.
