Power:Power measures how quickly work is done or how quickly energy is transferred or transformed. In rotational systems, it represents how fast torque can be applied.
Conservation of Mechanical Energy: Just as mechanical energy (kinetic + potential) is conserved in linear systems, it also holds true for rotational systems where rotational kinetic energy can be converted into potential rotational energy without any external forces acting.
Rolling Motion: Rolling motion occurs when an object simultaneously rotates and translates without slipping. It involves the conversion of both linear and rotational kinetic energy.
