PPT-Energy, Work & Power

Regents Physics Mr Rockensies Introduction to Energy How does energy manifest itself physically What is energy Energy is the ability to do Work Energy exists in several different forms Almost all energy on Earth can be traced back to the Sun. Energy. The capacity of vigorous activity. The ability to act. The capacity of a body or a system to do work. (and heat). . . Mechanical Energy. Kinetic + Potential. E = U+K. . h. Chemical Energy:. 14) explain the relationship between work and power (using narrative and mathematical descriptions) and apply to realistic situations (GPS, HSGT) (SCPH_C2005-14). 14a) calculate the work on a body by constant force.

Students will evaluate the forms and transformations of energy. a. Analyze, evaluate, and apply the principle of conservation of energy and measure the components of work-energy theorem by Unit 4: Work, Power, and Energy I. Work When a force acts upon an object to cause a displacement of the object, it is said that work was done upon the object. There are three key ingredients to work: Why not?. Does energy just disappear? No!. Law of Conservation of Energy. : energy cannot be created nor destroyed.. -energy can change forms. 1. st. Law of Thermodynamics. : energy can do work, or produce heat, but it is always conserved.. is essential for life, and is required to fuel many different body processes, growth and activities. . These include:. keeping the heart beating;. keeping the organs functioning; . maintenance of body temperature;.
