Question

1. How does the force of gravitation between two objects changewhen the distance between them is reduced to half ?
2. Gravitational force acts on all objects in proportion to their
masses. Why then, a heavy object does not fall faster than alight object?
3. What is the magnitude of the gravitational force between the
earth and a 1 kg object on its surface? (Mass of the earth is
6 x 1024 kg and radius of the earth is 6.4 x 106 m.)
4. 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?
5. If the moon attracts the earth, why does the earth not movetowards the moon?
​

Answer 1

Answer:

The force of gravitation between two objects is inversely proportional to the square of the distance between them therefore the gravity will become four times if distance between them is reduced to half.

Answer 2

Explanation:

objects changewhen the distance between them is reduced to half ?
