  1. Unit 3 Warm Ups!

  2. 10-17-2013 • What is Energy?

  3. 10-18-2013 • One of our formulas for work is W = F x d. What needs to happen to the F and d for work to have been done?

  4. 10-21-2013 • When do we use the mechanical work formula, and when do we use the work against gravity formula?

  5. 10-23-2013 • Calculate the work the wrecking ball does and the power it had: • A wrecking ball hits the building with a force of 430 N. The wall fell back and crumbled 15 feet from where it had stood. It only took the wall a total of 2 seconds to completely fall apart.
