This document contains a 30 question quiz about energy, work, and power. It tests understanding of key concepts like:
1) The differences between energy, work, and power - including their standard units of joules, watts, etc.
2) The different types of energy - kinetic, potential, chemical, elastic, etc. and examples of each.
3) Laws and concepts like the conservation of energy and definitions of energy transformation and transfer.
4) Equations to calculate potential energy, kinetic energy, work, and power.
The quiz covers foundational physics concepts in a multiple choice format.
