CBSE Class 9 Answered

Dear student,

The question itself has the answer. Why do we fly in moon or in space? Because there is no gravitational pull that keeps us attracted towards earth's surface.

Weight is essentially a measure of the downward force (i.e. lbs) generated by an object towards the planet.

This force is caused by gravity. The amount of this force is directly proportional to the amount of gravitational pull between the object and the planet.

The gravitational pull between two objects increases as the mass (the amount of matter) in the two objects increases.

The Earth is larger than the Moon, and has more mass, hence any object will generate less downward force and in turn be lighter or weigh less on the Moon than it would on Earth.

Hence the weight of an object on the moon 1/6th the weight of earth.

Hope this helps.
