1. For inferior goods, the Engel curve has a negative gradient . 2. Next is a descent, with the steepest after with a 16 % negative gradient . 3. Since the force is the negative gradient of the potential energy, we have in this case 4. The force on an atom is defined as the negative gradient of the potential energy function. 5. Next was a descent, with the steepest point after at a 16 % negative gradient . 6. A red arrow originating at a point shows the direction of the negative gradient at that point. 7. To reach the goal position, a robot only needs to follow the negative gradient of the surface. 8. According to Fick's laws, the diffusion flux is proportional to the negative gradient of concentrations. 9. In other words, there is a "'steeper negative gradient "'than positive gradient. 10. For example, the marginal revenue curve would have a negative gradient , due to the overall market demand curve.
