What do we call the gravitational force between the earth and an object?
Gravitational force between the earth and an object is known as the weight of the object.
What are the differences between the mass of an object and its weight?
What do you mean by acceleration due to gravity?
Calculate the force of gravitation between the earth and the Sun, given that the mass of the earth $= 6 \times 10^{24}\, kg$ and of the Sun $= 2 \times 10^{30}\, kg$. The average distance between the two is $1.5 \times 10^{11}\, m$.
Amit buys few grams of gold at the poles as per the instruction of one of his friends. He hands over the same when he meets him at the equator. Will the friend agree with the weight of gold bought? If not, why? [Hint: The value of $g$ is greater at the poles than at the equator.]
How does the force$(F)$ of gravitation between two objects change when the distance between them is reduced to half ?
