Rahul: But how does that happen?

Father: That’s because the gravitational pull is only one-sixth of the gravitational pull

that exists on Earth. The astronauts who went there found that their 360 pound

backpack (Earth weight) weighed only 60 pounds on the moon. They also reported
that the weightless conditions there allowed them to take big leaps in the air!

Rahul: So, they were all floating around on the moon?

Father: Yes, what happens is that, if you weighed 18 kgs on the Earth, you would weigh
only 3 kgs on the moon.

Rahul: It’s all very interesting, daddy.
Father: There are many things which scientists have not been able to explain. They are yet

to explore them. When Neil Armstrong set his foot on the moon, he said, “That’s

one small step for a man, one giant leap for mankind.” So the journey doesn’t end
with one man. The study of the moon will continue.

Rahul: It’s indeed wonderful, daddy. Thank you very much.
