Conservative Forces and Potential Energy
... The only physically significant quantity is the change in potential energy, and not the absolute value of the potential energy. For this reason, in problem solving, we usually choose a convenient point (table top level, ground level, sea level, etc.) and set the potential energy at this level to be ...

... Adding the two equations gives −u′2 e−2x = 4ex , from which we find that u′2 = −4e3x . Plugging this into the first of the two equations gives u′1 e−x = 4e3x e−2x , so that u′1 = 4e2x . We deduce that u1 = 2e2x and u2 = − 43 e3x , so that a particular solution is given by ...

Springs, for example, are coils of some material(steel or plastic for example) which do this very well if the deformation is not too large. When the deformation is performed within the elastic limits of t ...

Work and Kinetic Energy The concept of WORK
... CHAPTER 6: Work and Kinetic Energy The concept of WORK has a very precise definition in physics. Work is a physical quantity produced when a Force moves an object through a Displacement in the same direction as the force. Work is a scalar quantity. In physics, in order to get the Work done, there mu ...
