17. How do you know when work is being done?
18. If you do work on an object, how will the object’s energy change? (increase or decrease or stay the same)

24. Using the picture on pg.157 in your textbook, what energy transformation occurs as the drums are lifted? Once the drums are lifted and the drummer is standing still holding the drums, is work being done? Explain.
25. What energy transformation occurs in plants as they make food from sunlight?
26. When you ride a bike, what is the energy transformation?
