Figure 7.8 The speed of a roller coaster increases as gravity pulls it downhill and is greatest at its lowest point. Viewed in terms of energy, the roller-coaster-Earth system’s gravitational potential energy is converted to kinetic energy. If work done by friction is negligible, all ΔPEg is converted to KE.

The potential energy stored in the spring is given by U=-\dfrac {1} {2}kx^2. U = −21kx2. Let's start with the proof. Let's start with the derivation of the above equation. Let the spring be stretched through a small distance dx dx.

Potential energy is particularly useful for forces that change with position, as the gravitational force does over large distances. In Potential Energy and Conservation of Energy, we showed that the change in gravitational potential energy near Earth’s surface is \[ \Delta U = mg(y_2− y_1) \label{simple}\]
