Question

According to Newton's law of gravitation, every object in the universe attracts every another object, then why dont objects move under the influence of this force of gravitation?

Answer 1

G is 6.673 × 10^–11 N m² kg^–2.
look at this value how small a number it is
so the formulae for gravitational attraction b/w M1 and M2 is GM1M2/r^2
So this to feel the force ,the force has to be significant but as u can see G's value is extremely small so until unless one of the mass M1 ,M2 is significantly large , the value of force will be very less so less that we won't be able to experience it when one mass is of earth this force becomes significant because earth's mass is too much and we can feel that it's pulling us down thoroughly enjoyed answering this..keep exploring .. cheers!!
