du 2. Potential energy is defined so that the force is the negative derivative of the potential energy associated with it: F = - (This means that U = - SF dr, if you have learned integrals in your calculus class.) dr. See if you can guess the potential energy U that goes with Newton's universal gravitational force: F, = -G M3M2. The negative sign here indicates that it's an attractive force. If you know how to integrate, do that...

A potential energy function is given by U(x) = (x ^−8) *e^ (x ^2) . Let’s only focus on the region where x > 0. a) Find the position where the potential energy is a minimum b) For small oscillations around this minimum, what is the angular frequency ω? c) At what distance (either to the left or right) from the equilibrium point is the exact value of the force (derived from the full potential) more than 10% different from...
