An object weighs 9 N on the surface of the Earth. What would be its weight, when measured on the surface of a planet where the acceleration due to gravity is 9 times that on the surface of the Earth?

The acceleration due to gravity at the Earth’s surface depends on

If the distance between the Earth and the Sun were twice what it is now, the gravitational force exerted on the Earth by the Sun would be –

If the Moon is brought closer to the Earth such that its distance from the Earth becomes half of the original distance, then the gravitational force of attraction between the Earth and the Moon would…

What happens to the gravitational force between two objects if the mass of one object is doubled and the distance between them is also doubled?

An astronaut whose weight on the Earth is 600 N experiences weightlessness on International Space Station orbiting around the Earth. It means that
