(iii) the masses of both objects are doubled?
7. What is the importance of universal law of gravitation?
Answers
Answer:
Explanation:
Gm1 m2/ r^2
if one mass doubled gravitaional force also doubled if both doubled then it will become 4 times
G = 6.67 x 10-17
The Importance of Universal law of gravitation lies in the fact, that it was successful in explaining many phenomena such as.
(i) how different objects in this universe, affect others,
(ii) how gravity is responsible for the weight of a body and keeps us on the ground,
(iii) how the lunar motion around the earth occurs
(v) how the planetary motion takes place
(vi) how the tidal waves originate
Answer:
Explanation:
If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
