A-LEVEL PHYSICS: 7.2.3: Graphical Representation of Gravitational Potential (SaveMyExams)

Question 1

g, V, r are related by the equation:

Answer 1

g = ∆V/∆r

Question 2

key features of gfs-radius graph: (4)

Answer 2

-all values of g are +
- r inversely proportional to g
-area under graph = ∆V
-graph has steep decline as r increases
