This topic covers Power.
The Main Idea
Power is the rate of doing work or the amount of energy consumed over an interval of time.
A Mathematical Model
When a force is applied over a distance in a unit of time, power is calculated by:
- [math]\displaystyle{ power = \frac{F \Delta r}{\Delta t}, where '''F''' is force, '''Delta r''' is displacement and '''Delta t''' is the duration of time. It then follows that the instantaneous power is: :\lt math\gt power = F\cdot v. }[/math]
A Computational Model
