Concepts of work, kinetic energy and potential energy are discussed; these concepts are combined with the work-energy theorem to provide a convenient means of analyzing an object or system of objects moving between an initial and final state.
Height and weight chart Hidden causes of weight gain 9 medical reasons for putting on weight. Body size, age, gender and genes all play a role in the speed of your metabolism. Muscle cells require more energy to maintain than fat cells, so people with more muscle than fat tend to have a faster metabolism. As we get older, we tend to gain fat and lose muscle.

The laws of thermodynamics describe how the energy in a system changes and whether the system can perform useful work on its surroundings. Is thermodynamics physics? Yes, thermodynamics is a branch of physics that studies how energy changes in a system. The key insight of thermodynamics is that heat is a form of energy that corresponds to mechanical work (that is, exerting a force on an object.
Application and Practice Questions; Bar Chart Illustrations; Lesson 2 has thus far focused on how to analyze motion situations using the work and energy relationship. The relationship could be summarized by the following statements: There is a relationship between work and mechanical energy change. Whenever work is done upon an object by an external or nonconservative force, there will be a.
The energy of this water cycle, which is driven by the sun, can be tapped to produce electricity or for mechanical tasks like grinding grain. Hydropower uses a fuel—water—that is not reduced or used up in the process. Because the water cycle is an endless, constantly recharging system, hydropower is considered a renewable energy.
