Question

important points on gravitation

Answer 1

hey mate here is your answer
(i) Gravitational force is a central as well as conservative force.

(ii) It is the weakest force in nature.

(iii) It is 1036 times smaller than electrostatic force and 10’l8times smaller than nuclear force.

(iv) The law of gravitational is applicable for all bodies, irrespective of their size, shape and position.

(v) Gravitational force acting between sun and planet provide it centripetal force for orbital motion.

(vi) Gravitational pull of the earth is called gravity.

(vii) Newton’s third law of motion holds good for the force of gravitation. It means the gravitation forces between two bodies are action-reaction pairs

Answer 2

1) Gravitational force acting between sun and planet provide it centripetal force for orbital motion.
2) Gravitational pull of the earth is called gravity.
3) Newton's third law of motion holds good for the force of gravitation.
4) It expresses the force between two point masses (of negligible volume).
Hope this will help you.. ✌
