kokonaisenergia
Kokonaisenergia, Finnish for total energy, denotes the total energy of a physical system. In classical mechanics it is formed by the sum of kinetic energy and potential energy: E = T + V. Kinetic energy depends on motion (for a point mass, T = 1/2 m v^2), while potential energy arises from position in a force field (for example, gravitational U = mgh or a spring energy 1/2 k x^2).
In conservative systems the total energy is conserved: as a system evolves, energy continuously shifts between
In relativistic physics the concept generalizes to include rest energy. The total energy of a particle satisfies
