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:
