Physics 21.4 Planetary Fields Flashcards
1
Q
What is the combined equation using gravitational field strength and the gravitational constant?
A
g=((GM)/r^2)
- g is the magnitude of gravitational field strenght in [N kg^-1]
- G is the gravitational constant in [N m^2 kg^-2]
- M is the mass of the object creating the field in kilograms [kg]
- r is the distance from the point mass in metres [m]

Q
What does the area under a g-R graph represent?
A
The area under the g-R curve can be used to find the gravitational potential.
3
Q
What is the equation for combined gravitational fields?
A
g=Σ((GM)/r^2)
