1) write the formula to find the magnitude of gravitational force between earth and an object on earth's surface
2) how does the value of gravitational force 'f'change between two objects?
3) what is direction of an object moving with an acceleration due to gravity?
F = G Me m/R^2 = approximately m g
because G Me/R^2 is pretty much constant around earth surface
Toward the center of mass of the object that is pulling it, for example toward earth center.
