Definitions of quantities, explanations of equations, and worked out example problems.
A development of the physics definition of work and why you don't do any when it seems like you do.
Describes the conditions for equilibrium and distinguishes stable, unstable and neutral equilibrium.
Describes potential energy as energy required to move away from equilibrium; describes gravitational PE.
Describes kinetic energy as the result of work and shows a derivation of the equation for KE.
Illustrates how energy undergoes transformations without increasing or decreasing in quantity.
Simple discussion of power and derivation of P=Fv from P=W/t. Remember: it's wrong to say that power is the rate at which work is done. How much work does a 60-watt lightbulb do each second?

[Virtual Demonstration] at Teachers Pay Teachers
A set of questions and illustrations to accompany a segment of Physics: Cinema Classics that involves energy transformations.
With Numbers [Virtual Demonstration] at Teachers
A set of calculations to follow the "Nailed!" demonstration.
|3||Physics in The Fountain of
Fizz [Virtual Demonstration] at Teachers Pay
The physics of the Diet Coke-Mentos geyser. Not the chemistry. The physics.
With an M (QuickTime)
Part of the "Physics Begins with an M" series. This is a QuickTime export from Keynote that has been Zipped.
Energy Begins With an M Keynote
A nifty Keynote presentation of the M's. (Keynote is Apple's presentation software; PowerPoint is Microsoft's presentation software.) Trust me, neither Keynote nor PowerPoint are The Great Saviors of education. I recommend using them sparingly if at all. Better to teach!
Universe: Potential Energy (College) [Question
