Teaching Physics with the Physics Suite
where m is the mass of the object, ME is the mass of the Earth, r is the distance the object is from the center of the earth, and G is Newton's universal gravitational constant, 2/3 x 10-10 N-m2/kg2.
b) The formula stated above doesn't look like the "mgh" formula we know and love (?) from our previous work. Why don't these look the same? Which is right? If Newton is right, how can we use mgh and get away with it?
