The Power and Efficiency Calculator is provided in support of our Physics Tutorials on Work, Energy and Motion which explores Motion, the different types of energy, kinetic energy, gravitational potential energy, elastic potential energy. power and efficiency with practical working examples and formula. A list of the supporting Work and Energy Physics Tutorials is available at the bottom of this page. This calculator will calculate:
| Output Power (Pout) W | |
| Efficiency [ Equation 1 ] (e) | |
| Efficiency [ Equation 2 ] (e) |
Note:
Please note that the formula for each calculation along with detailed calculations is shown further below this page. As you enter the specific factors of each force calcualtion, the Power and Efficiency Calculator will automatically calculate the results and update the formula elements with each element of the force calculation. You can then email or print this power and efficiency calculation as required for later use.
