Week 5: Energy

[1] Relevant Equations/Concepts⚓︎

UPDATE [March 31]: Please see this page for a much better explanation on how to solve most problems that involve energy/work.

[3] Recitation Prep⚓︎

In addition to section 1, I recommend reviewing the following concepts in the videos above. They will probably come up in recitation problems:

• Graphs where force is on one axis, and displacement is on the other.
• Pushing box across rough surface at an angle.
• Box sliding down rough incline.
