Potential energy is the stored or pentup energy of an objectIt is often contrasted with kinetic energy In physics, potential energy is the energy which an object has due to its position in a force field or which a system has due to the way its parts are arranged Common types include the gravitational potential energy of an object that depends on its vertical position and mass, theExample 1) How much cement could be loaded on a 2 m high lorry by the energy required to heat 1 liter of water by °C?Example 41 a force F acting on an object varies with distance x as shown in Fig 47 calculate the work done by the force as the object moves from x = 0 to x = 6 m Fig 47 Solution The work done by the force is equal to the total area under the curve from x = 0 to x = 6 m this area is equal to the area of the rectangular section from x = 0 to x = 4 m, plus the area of triangular
