GUIDES
1 Energy Examples
Definitions of quantities, explanations of equations, and worked out example problems.
2 Work / Simple Machines
A development of the physics definition of work and why you don't do any when it seems like you do.
3 Equilibrium & Stability
Describes the conditions for equilibrium and distinguishes stable, unstable and neutral equilibrium.
4 Gravitational Potential Energy
Describes potential energy as energy required to move away from equilibrium; describes gravitational PE.
5 Kinetic Energy
Describes kinetic energy as the result of work and shows a derivation of the equation for KE.
6 Conservation of Energy
Illustrates how energy undergoes transformations without increasing or decreasing in quantity.
7 Power
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?



JOBS
1
Equilibrium [Springboard] at TPT
A classroom discussion to accompany a discussion (with demonstrations) of stable, unstab;le, and neutral equilibrium.
2 Work Springboard - Answers - Presentation (Zipped QuickTime)
Introduces the concept of physical work through illustrative examples. Addresses positive, negative, and zero work.
3 Potential Energy [Springboard] at TPT
Introduces the concept of gravitational potential energy and its dependence on mass, height, and gravitational acceleration.
4
Potential Energy Ranking [Job] at TPT
Ranking tasks for the gravitational potential energy of suspended objects.
5 Kinetic Energy [Springboard] at TPT
Introduces the concept of kinetic energy and its dependence on mass and the square of speed.
6
Momentum and Kinetic Energy Ranking [Job] at TPT
Ranking tasks involving momentum and kinetic energy of moving objects.
7 Conservation of Energy Springboard - Answers - Presentation (QuickTime)
A classroom demonstration and discussion involving loading and firing a dart gun.

LABS - The unlinked titles below are available in the Conceptual Physics lab manual from Pearson Education - Amazon link
1 An Uphill Climb Prelab - An Uphill Climb
Laboratory comparison of using a steep path or a shallow path to crest a hill. Which--if either--is better from an ideal energy consideration?

Fire It Up [PhET] at TPT
A comparison of maximum kinetic energy and maximum kinetic energy of a ball launched vertically using PhET's Projectile Motion simulation.
2 Catch The Pop-Up
A comparison of maximum kinetic energy and maximum kinetic energy of a ball launched vertically.



DEMOS - The unlinked titles below are available in the Conceptual Physics lab manual from Pearson Education - Amazon link
1 Nailed [Virtual Demonstration] at TPT
A set of questions and illustrations to accompany a segment of Physics: Cinema Classics that involves energy transformations.
2 Physics in The Fountain of Fizz [Virtual Demonstration] at TPT
The physics of the Diet Coke-Mentos geyser. Not the chemistry. The physics.

Energy Begins 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!
3 Mechanical Universe: Potential Energy (College) [Question set at TPT]
This episode traces back to the origins of the idea of potential energy and relates potential energy to equilibrium and stability.
 4 Mechanical Universe: Conservation of Energy [TPT question set]
This episode develops conservation of energy.
5
Energy Crossword Puzzle at TPT
Not a typical academic subject matter crossword. This one adds general high school vocabulary words. Over 100 words and 150 crosses in total.
6
Practice Test Questions
Sample test questions covering energy.
