Spänningsenergi

Spänningsenergi, often referred to as potential energy, is the energy stored within an object or system due to its position or configuration. This stored energy has the capacity to do work. A common example is gravitational potential energy, which is the energy an object possesses because of its height above a reference point. The higher an object is, the greater its gravitational potential energy. This energy is calculated as the product of the object's mass, the acceleration due to gravity, and its height.

Another form of spänningsenergi is elastic potential energy. This is the energy stored in a deformed elastic object, such as a stretched rubber band or a compressed spring. When the object is released, this stored energy is converted into kinetic energy, the energy of motion. The amount of elastic potential energy depends on the stiffness of the material and the extent of its deformation. Chemical spänningsenergi is stored in the bonds of molecules and is released during chemical reactions, like the burning of fuel. Electrical spänningsenergi is stored in electric fields due to the arrangement of electric charges. In all these cases, spänningsenergi represents stored capacity for change or action.
