Derivative of potential energy
WebIf gravity can do only two joules of work then we will say it's potential energy is only two joules. Okay, so from this we can immediately say the gravitational potential energy by … Webto be zero. In some special cases, say for example a potential energy described by U(x) = x4, the second derivative could vanish at the potential minimum. But, for a totally arbitrary potential energy function, it will typically be the case that U 2 = 1 2 U00(x) 1 2 k>0; (7) where Kis some positive constant (positive because we have a minimum, and
