10 cards from this deck
Work done per unit mass to move an object from infinity to that point
Zero
Negative
V=−GMrV = -\frac{GM}{r}V=−rGM
Energy required to move a unit mass between two points
mΔVm \Delta VmΔV
Surfaces where gravitational potential is same at every point
Zero (no work required)
Inversely proportional: V∝1rV \propto \frac{1}{r}V∝r1
g=−ΔVΔrg = -\frac{\Delta V}{\Delta r}g=−ΔrΔV
