Chapter 4, Problem 40EAP

Group Activity: Your Ultimate Energy Source. Work as a group to answer each part. Note: You may wish to do this activity using the same four roles described in Chapter 1, Exercise 39.

a. According to the law of conservation of energy, the energy your body is using right now had to come from somewhere else. Work in groups to make a list going backwards in time describing how the energy you are using right now has pro-ceeded through time.

b. For each item on the group’s list, identify the energy as kinetic energy,gravitational potential energy, chemical potential energy, electrical potential energy, mass-energy, or radiative energy
