Conservation of Energy Discussion (from 16.3) Here is a brief

... Here is a brief discussion of the origin of the term conservative for a vector field, F, that is the gradient of some potential function, f . Mathematically, this relationship is F = ∇f , but let’s see where the terms come from. FIRST, let F(x, y, z) be a force vector field that moves a particle of ...

... Answer: The acceleration is negative. In 1D, F = - dU/dx. The slope of the curve dU/dx is positive at x=A, so F = ma = -dU/dx is negative there. The force F and the acceleration a = F/m are negative at x=A (meaning their directions are to the left, toward negative x.) The kinetic energy might be zer ...
