Question

Given a potential energy function U(x), the corresponding force  is in the positive x direction if:

Quizplus · Accepted Answer

The force is given by the negative gradient of the potential energy function, i.e. 11eaafba_af46_291c_a7a5_2bf03ef3c1ec_TB3976_11 = -dU/dx. If U is a decreasing function of x, then dU/dx < 0, and hence 11eaafba_af46_291c_a7a5_2bf03ef3c1ec_TB3976_11 > 0. Therefore, the correct answer is D.
