3.4 Gravitational field and potential

Question 1

In a uniform gravitational field, what is the relationship between the gravitational field and the change in the gravitational potential difference

Answer 1

change in gravitational potential= gravitational field x change in height
change in Vg = g x change in height

Question 2

What is the equation for the gravitational potential in a radial field

Answer 2

Vgrav = -Gme/r
