What happens to the force between two objects, if
(i) the mass of one object is doubled?
(ii) the distance between the objects is doubled and tripled?
(iii) the masses of both objects are doubled?
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 kg object on its surface? (Mass of the earth is 6 × 1024 kg and radius of the earth is 6.4 × 106
m.)
Gravitational force acts on all objects in proportion to their masses. Why then, a heavy object does not fall faster than a light object?
How does the force of gravitation between two objects change when the distance between them is reduced to half ?
You have a bag of cotton and an
iron bar, each indicating a mass
of 100 kg when measured on a
weighing machine. In reality,
one is heavier than other. Can
you say which one is heavier
and why?
You find your mass to be 42 kg
on a weighing machine. Is your
mass more or less than 42 kg?
