Either in a course or in self-study Physics of Energy IUnderstanding the physics of energy means learning about two sorts of thingsHow does each particular form of energy workWhat general principles unify the physics of energyapplying to energy in all its different forms. Energy: scalar quantity associated with a state (or condition) of one or more When our physics problems involve forces for which we can have a potential energy function, we usually think about the change in potential energy of the objects rather than ChapterEnergy, Kinetic Energy, and Work. At the most fundamental level there are three kinds of energyKinetic energy – energy due to motionPotential energy – energy due to interaction a. The faster an object moves, the greater its kinetic energy. Potential energy U represents stored energy, e.g., in a Definitions (donʼt memorize) Energy is the ability to do work. Gravitational potential X. Determining potential energy values: gravitational potential energy, elastic potential energy. Acceleration of the expansion of the universe is one of the most exciting and significant discoveries in physics, with The physics of energy involves a close interplay between underlying physical theory and applications. Katrin Becker and Melanie Becker, Texas A&M University Jaffe and Taylor have produced in a single volume a comprehen sive text on energy sources, energy conversion technologies, and energy uses from the unifying vantage of physics. WeÕll start with the general principles. Thus, in physical principles are developed in tandem with their The amount of work done on a system is the change in energy of the system. These are known as the laws of (Work is defined numerically as the magnitude of a force multiplied by the amount the force moves in the direction of the force.) Alternative definition for Energy: anything that can be turned into heat courses on energy physics and promises to become a classic for years to come. (We will define work later.) The English sentence “The work done equals the amount of energy transformed” we can write as •It turns out that energy possesses a fundamental characteristic which makes it very useful for solving problems in physics: **Energy is ALWAYS conserved** Kinetic energy K is energy associated with the state of motion of an object. We’ll use the symbol W for work and the symbol U for energy.
