Document Summary
To move matter in a direction it would no move if left alone. All organisms require energy to stay alive. Energy exists in two states: kinetic energy, potential energy. 5. 1: energy is the capacity to perform work. Kinetic energy: the energy of motion, moving objects perform work by causing matter to move. Potential energy: stored energy, objects that are not actively moving but have the capacity to do so possess energy. Potential energy vs kinetic energy: a boulder perched on a hilltop has potential energy, as it begins to roll down the hill some of the energy is converted into kinetic energy. Much of the work that living organisms carry out is involves transforming potential energy to kinetic energy. Chemical energy: the potential energy of molecules. 1: most important type of energy for living organisms. Most convenient way to measure energy is in the form of heat: =a measure of the random motion of molecules.
