... A block rests on a horizontal frictionless surface. A string is attached to the block, and is pulled with a force of 45.0 N at an angle above the horizontal, as shown in the figure. After the block is pulled through a distance of 1.50 m, its speed is 2.60 m/s, and 50.0 J of work has been done on it ...

... Not all of the energy in the roller coaster system is conserved in a non-idealized system. This is because of nonconservative forces. Friction is the main cause of energy leaks in the system and the reason why mechanical energy is not fully conserved. The friction between the train and it’s tracks a ...

... Energy can neither be created not destroyed, but can only be converted from one form to another. Heat energy is the kinetic or vibrational energy of molecules. The result of a non-conservative force is often to remove mechanical energy and transform it into heat. Examples of heat generation: sliding ...

Potential energy
... In an isolated system where only conservative forces cause energy changes, the kinetic energy and potential energy can change, but their sum, the mechanical energy Emec of the system, cannot change. The mechanical energy Emec of a system is the sum of its potential energy U and the kinetic energy K ...
