Living organisms, like you, get their energy to move and do work from eating food. Trace the energy transformations that occur from the original radiant solar energy used by plants to mechanical energy in living systems.

2. Plants convert the radiant solar energy to chemical energy through the process of photosynthesis. The plant is harvested using mechanical energy. The machine that does the harvesting converts chemical energy into mechanical energy. Transportation and processing will also involve the conversion of chemical energy to mechanical energy. When people eat food, their bodies convert the chemical energy stored in food into mechanical energy.

4. Potential Energy: Stored energy Amount of useable energy within a body at rest Kinetic Energy: Energy that a body has as a result of its motion.

6. Kinetic and potential energy are converted into one another throughout the path of the ball. Before the player releases the ball, the ball has potential energy but no kinetic energy because it is not moving. When the player releases the ball at point A, he sets it into motion by exerting a force, thereby giving it kinetic energy. As the ball rises to point B, the ball slows down. In the process, kinetic energy is converted into potential energy. When the ball reaches the top of its path at point C, much of the kinetic energy has been converted into potential energy. This is the point where the ball has the most potential energy. As the ball falls to point D, the ball speeds up, and its height decreases. As a result, potential energy is converted back into kinetic energy.
