The Power of a Motor - GCSE Physics

Показать описание

This video details a simple experiment that you could do to investigate the power of a motor. By increasing the height of a small mass, we can calculate the gravitational potential energy that is transferred to the mass. If we also measure the time this takes, we can calculate the power of the motor by using the equation P = E/t,

We have to assume that all the energy is usefully transferred from the motor to the mass.
