during an energy transformation, the total amount of energy stays the same. so, when one type of energy decreases, at least one other type of energy will increase. read the passage about the next part of the ride. think about how kinetic energy, chemical potential energy, and thermal energy changed. ellen biked in a straight line along the street. then, to avoid the sun, she moved over to ride under the shade of some trees. but as she pedaled faster and sped up, ellen started to feel hot even in the shade. decide how each type of energy changed. ellens kinetic energy increased decreased chemical potential energy stored in ellens muscle cells increased decreased ellens thermal energy increased decreased

Answer

# Brief Explanations: 1. Kinetic energy is related to speed. Since Ellen sped up, her kinetic energy increased. 2. Chemical - potential energy in muscle cells is used to do work. As she pedaled faster, she used more energy from her muscle cells, so the chemical - potential energy decreased. 3. She started to feel hot, which means her body temperature increased, so her thermal energy increased. # Answer: Ellen's kinetic energy: Increased Chemical potential energy stored in Ellen's muscle cells: Decreased Ellen's thermal energy: Increased
