WebThe Work-Energy Principle is the physical phenomenon that the work done on a system is equal to the change in the system's kinetic energy: W = Δ K. It can be derived from Newton's second law F = m a and the definition of kinetic energy K = 1 2 m v 2. WebNet metering is a billing mechanism that credits solar energy system owners for the electricity they add to the grid.
