... charge is placed on the plates (V = Q / C). Since the V changes as the Q is increased, we have to integrate over all the little charges “dq” being added to a plate: DU = q DV leads to U = V dq = q/C dq = 1/C oQ q dq = Q2 / 2C. And using Q = C V, we get ...

... • Gravitational Potential Energy depends on the mass, its height, and the acceleration due to gravity. The gravitational energy an object gains is equal to its weight (mg) multiplied by its height (h). Potential Energy (PE) = mgh • Gravitational potential energy is expressed in joules, the mass is e ...
