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{ P = \frac{F \Delta r}{\Delta t} }[/math] where F is force, Δr is displacement and Δt is the duration of time.

It then follows that instantaneous power is

[math]\displaystyle{ P = F\cdot v }[/math] where v is velocity.

A Computational Model

How do we visualize or predict using this topic. Consider embedding some vpython code here Teach hands-on with GlowScript

Examples
