What potential energy would this column of eggs have? (Let the potential energy of the bottommost egg be zero.) calculus. The Great Pyramid of Cheops was built on the Ghiza Plateau just outside of what is now Cairo, Egypt some time between 2589 and 2566 BCE. It serves as the final resting place of the Pharaoh Cheops (also known as Khufu).
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:
