Question
you are cooking beans over a campfire. by the light of the fire, you read that one serving of beans is 120 calories. after eating the beans, you go for a hike along a stream. all of the items described here have energy. identify the form of energy each contains. labels ① drop zones reset all flames beans moving water firewood hiking potential energy (1/2) kinetic energy (2/2)
Potential energy is stored energy. Beans have chemical - potential energy stored in their chemical bonds, and firewood has chemical - potential energy from its chemical composition. Kinetic energy is energy of motion. The flames have kinetic energy as the molecules are in rapid motion. Moving water has kinetic energy due to its motion. Hiking implies a moving person, so it has kinetic energy.
