## PHYSICS 12 UNIT 3 - Energy Power Efficiency

This unit looks at kinetic and gravitational potential energy of objects and the efficiency of processes. It does not look at heat transfer, which is included in Physics 11.

1. Complete the worksheets using the videos, keys, in class lectures, posted slides, and peers

2. You need to write two quizzes, ask for them when you are ready. You will write one test at the end of the unit (the end of most units)

All quizzes and tests will be open book, on your own, no internet connection

3. Lab(s)

A lab using Hot Wheels cars, challenging you to reduce the amount of energy lost to heat via friction.

You can, as an alternate, look at the efficiency of everyday devices. A timely topic as this is likely where our "green" technology will continue to develop.

4. Demos.

We may include you in some of the more interesting demos around heat from the P11 curriculum.
