Work-rotational motion refers to the motion of an object around a fixed axis, where the force applied does not act through the center of mass of the object. It involves both linear motion and rotational motion.
The equation for work-rotational motion is W = τθ, where W is the work done, τ is the torque applied, and θ is the angular displacement.
In work-linear motion, the force applied acts through the center of mass of the object, resulting in only linear motion. In work-rotational motion, the force applied does not act through the center of mass, causing both linear and rotational motion.
Torque is the measure of the rotational force applied to an object. In work-rotational motion, the work done is directly proportional to the torque applied. As torque increases, so does the work done.
Work done in rotational motion results in the transfer of energy to the object. This energy can be either kinetic or potential and is dependent on the type of work done (such as lifting a weight versus spinning a disc).
