In a system the potential energy is related to forces acting between bodies inside the system. Kinetic energy of a moving body is defined as K=(1/2)*m*v^2 where m is the mass of the body and v its...
HistoryA roller coaster train going down hill represents merely a complex case as a body is descending an inclined plane. Newton's first two laws relate force and acceleration, which are key concepts...
Both are forms of energy. Potential energy is the available energy that could be used and Kinetic energy is the energy actually being used. Think of Potential energy as being a high cliff with water...
