E p m g h Example: A box has a mass of 5.8kg. The box is lifted from the garage floor and placed on a shelf. If the box gains 145J of Potential Energy (E p),
The force of gravity, which has a potential energy function given by \(U(y)=mgy\). We choose the gravitational potential energy to be zero when the pendulum hangs vertically (when \(\theta=0\) and \(y=0\)). The mechanical energy of the mass is conserved, and at any point is given by the sum of its kinetic and its gravitational potential energies:

The document provides examples of solving problems involving potential energy using the equation Ep=mgh. It shows a box gaining 145J lifting 2.5m, a 63kg man climbing 3.6m and gaining 2268J, and a 0.8kg ball pulled up a slope gaining 1.6J over a 0.2m vertical distance. The examples demonstrate using the equation to calculate potential energy, height, or mass from the other given values.
The only potential energy this ball can have is gravitational potential energy. The formula for gravitational potential energy is . We are given the height and mass of the ball. Using the given values, we can solve for the potential energy. Keep in mind that the displacement will be negative because the ball is traveling in the downward direction.
