Potential Energy Practice Problem. A fruit hangs from a tree. The fruit is a quarter of a kilogram and is about to fall to the ground. If the fruit is 10 meters from the ground, how much potential energy does it possess? Solve this problem using the potential energy formula.

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:

a. The potential energy U = m g h = 2 × 10 × 5 = 100 J. Here the positive sign implies that the energy is stored on the mass. b. This potential energy is transferred from external agency which applies the force on the mass. c. d. From the definition of potential energy, the object must be moved at constant velocity. So the net force acting on ...

Unleashing the Power Within: Potential Energy in Water. The most compelling example of potential energy in water is a hydroelectric dam. Water held at a height behind a dam possesses gravitational potential energy. This stored energy is directly proportional to the water’s mass, the acceleration due to gravity, and the height of the water.
