In this final section, we define work and power within the context of rotation about a fixed axis, which has applications to both physics and engineering. The discussion of work and power makes our treatment of rotational motion almost complete, with the exception of rolling motion and angular momentum, which are discussed in Angular Momentum ...
Compare this power formula for rotational motion around a fixed axis to power formula P = Fv for linear motion. There is no internal motion in a perfectly rigid body. As a result, the work done by external torques is not dissipated and continues to raise the body’s kinetic energy. Equation (2) gives the rate at which work is done on the body.

Combining this with the power equation provides insights into how changes in motion affect power consumption or generation. Power in Rotational vs. Linear Motion While power in linear motion is calculated as the product of force and velocity (\( P = F \cdot v \)), rotational power extends this concept to rotational systems by using torque and ...

Power for rotational motion is equally as important as power in linear motion and can be derived in a similar way as in linear motion when the force is a constant. The linear power when the force is a constant is P = \(\vec{F}\; \cdotp \vec{v}\).
Rotational Power Formula [Click Here for Sample Questions] Torque and frequency of rotation determine the power of rotational systems. Power may be determined by knowing the torque and rotations per minute data. The formula for rotational power is: P = [τ \(\times\) (2/Π) \(\times\) rpm]/60.
