Gravitation

What happens to the force between two objects, if the masses of both objects are doubled?

What happens to the force between two objects, if the distance between the objects is doubled and tripled?

Write the formula to find the magnitude of the gravitational force between the earth and an object on the surface of the earth.

State the universal law of gravitation.

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 = $6\times 10^{24} \mathrm{kg}$ and of the Sun = $2\times 10^{30} \mathrm{kg}$. The average distance between the two is $1.5\times 10^{11} \mathrm{m}$ and the gravitational constant is $G = 6.7 \times {10}^{-11} \mathrm{N} {\mathrm{m}}^2{\mathrm{kg}}^{-2}$.

What do we call the gravitational force between the earth and an object?

What is the importance of universal law of gravitation?

What happens to the force between two objects, if the mass of one object is doubled?

If the moon attracts the earth, why does the earth not move towards the moon?

The earth and the moon are attracted to each other by gravitational force. Does the earth attract the moon with a force that is greater or smaller or the same as the force with which the moon attracts the earth? Why?

What is the magnitude of the gravitational force between the earth and a $1 \mathrm{kg}$ object on its surface? (Mass of the earth is $6\times 10^{24}$ $\mathrm{kg}$, radius of the earth is $6.4\times 10^6$ $\mathrm{m}$ and the gravitational constant is $G = 6.7 \times {10}^{-11} \mathrm{N} {\mathrm{m}}^2{\mathrm{kg}}^{-2}$).

How does the force of gravitation between two objects change when the distance between them is reduced to half?
