Equation For Power Time And Energy. The relationship between power, energy, and time can be described by the following equation : The si unit of power is watt (w).
Rotation of rigid bodies. Angular momentum and torque From ppt-online.org
Proper statement is “change of kinetic energy” = power×time. P = work done per unit of time = vq/t = (v) (i) or power = voltage x current or volts x amperes. A watt is one joule.
