Why is Newton's law of gravitation called universal law ?
What are the two factors that affect the gravitational force? How do they affect?
What type of forces act on the planets while revolving around the sun?
Define force ? SI unit and CGS unit. (Gravitation)
What happens to the force between two objects, if the distance between the object is doubled?
State Newton's law of gravitation. Calculate the force with which the moon pulls every kilogram of water in our rivers given that the moon is 3 x 105 Km away from Nepal and the mass of the moon is 7 x 1022 Kg.
What will happen to the gravitational force of attraction between two bodies when the mass of each body is doubled and the distance between them is tripled?
The mass of the earth is 6x1024 kg and its radius is 6400 km. What is the mass of a man weighing 977N in the spring balance? (Universal gravitational constant is 6.67x10-11 Nm2/Kg2)
