WebMar 2, 2024 · D. Energy Flow Flowing water contains energy in two forms, potential and kinetic. The potential energy at a particular point is represented by the depth of the water plus the elevation of the channel bottom above a convenient datum plane. The kinetic energy, in feet, is represented by the velocity head: Kinetic energy = 𝑉2 2𝑔 Equation 2F-2.04 WebDuring oscillation kinetic energy transforms into potential energy. Potential energy doesn’t need to flow straight back, the potential energy can be used later – as stored energy (e.g. if you stay on the top of the U ramp, or a skier on top of the hill). The pendulum is an efficient way of moving mass with a small amount of energy.
