Gravity is a VERY Tiny force
- Force between two objects each 1 Kg at a distance of 1 meter is F = G M1 M2 /R2 = 6.67 x 10 -11 N
- 1 N is about the weight of one apple on the earth
- The reason the effects of gravity are so large is that the masses of the earth, sun, stars, Ö. are so large -- and gravity extends so far in space
