code_begins P0 is the vector representation of co-ordinates of object of mass 'M'

• P0 is the vector representation of co-ordinates of object of mass 'm' x0,y0,z0 are the co-ordinates similarly x1,y1,z1 G=gravitational constant mag_r is the magnitude of displacement vactor r between abject 'M' and object 'm' force_mag is the magnitude of the gravitational force between them and its negative because it direction is towards P0 force_dir is the unit vector along the direction of force
