WebConservation of energy tells us that the work done by the gravitational field to make the mass accelerate must equal the loss of potential energy of the mass. If we use the symbol to denote this work, then. 18.18. where the minus sign reflects the fact that the potential energy of the ball decreases. WebDec 23, 2024 · A potential quantifies the capacity of a system to do work. A simple example is from mechanics: by lifting a weight, its potential energy increases. When the weight is dropped, that potential energy is converted into kinetic energy.
