Give the applications of universal law gravitation .

Explanation

(i) Dimensions of the heavenly bodies can be measured using the gravitation law. Mass of the Earth, radius of the Earth, acceleration due to gravity, etc. can be calculated with a higher accuracy.
(ii) Helps in discovering new stars and planets.
(iii) One of the irregularities in the motion of stars is called .Wobble. that lead to hte disturbance in the motion of a planet nearby. In this condition the mass of the star can be calculated using the law of gravitation.
(iv) Helps to explain gemination of roots is due to the property of geotropism, which is the property of a root responding to the gravity.
(v) Helps to predict the path of the astronomical bodies.
