Work Energy Test:

Concepts and Skills:

- Formulas that you should memorize (if you want extra points):
- Be able to define all of the items in the above formulas. You won't actually have to define them, but you should know what everything means.
- Units and their abbreviations, symbols, etc. (work, types of energy, power, efficiency)
- Know when each of the formulas can be applied, how it works, how (or if) its application may vary, and what units need to be used.
- Know how to work with, and convert between, different units for the same quantities. For power, some units are horsepower and Watts. For energy, some units are kiloWatt-hours, Watt-hours, Joules, calories, and food calories. Any necessary conversion ratios will be provided. You do not need to memorize them.
- Calculate work done by a varying force.
- Apply the various forms of the conservation of energy equation to a variety of situations.
- Derive equations by solving problems with variable names rather than concrete numbers.
