_________________
1) Every particle in the universe attract every other particle with a force called gravitational force.
2)Every particle in the universe attract every other particle with a force
which is directly proportional to the square of their masses and inversely proportional to the distance between them.
3) Importance:
i) Rainfall and snowfall is possible beacause of this gravitational pull of earth.
ii) The gravitational pull of the earth keep the satellite around the earth.
iii) Tides in oceans are due to gravitational force between water in oceans and the moon.
4)The universal gravitational constant is the force of attraction between two point masses of 1 kg each kept at a distance of 1 meter.
5) Gravitational force is inversely proportional to the distance so the new force becomes 4 times of previous force.
