I am currently solving a problem where I need to find the gravity in the ISS (distance 400km from Earth with Radius 6371km). I am using the formula g=GM/R^2 . One way to solve it would be to find GM by multiplying g(which is 9.81) and R^2 (which is known) and then to use it in GM/(R+400)^2 and get 8.7m/s^2.
I was wondering whether there was a way to use calculus to get this. If I integrate with respect to the distance (From 6371 to 6371+400) I get something around -1.02. Does that mean that the value changes from R to R+400 by -1.02 ?
I am having some trouble in deciding when and how to use calculus in physics (more specifically dynamics).
