# Chapter 8 - Potential Energy and Conservation of Energy - Questions: 2a

$AB \gt CD$ $\gt$ $(BC = DE)$

#### Work Step by Step

The application of force is shown on this graph when the potential energy changes (slope other than 0). The steeper the slope, the greater the force. AB has the steepest slope. CD has the next steepest slope. BC and DE have zero slope so the magnitude of force on the particle is zero.
