18. Gravity on the Moon has approximately 1/6th
of the strength of gravity on Earth.
A man who weighs 60kg on Earth would
weigh approximately 10kg on the Moon. His
mass, however, remains constant.
Acceleration
due to gravity
Moon=1.62 m/s²
Earth
=9.807 m/s²
19. Jupiter is a massive planet, the biggest in our solar system,
and it has a stronger gravitational pull than Earth. In
fact, its gravity is about 2.4 times as strong as Earth's. This
means, if you weigh 40 kg on Earth you would weigh 94 kg
on Jupiter.
20. A body weighs more at the poles than at the equator.
21. In space, weight doesn't exist but mass does.
In space you don't have gravity, so weight doesn't
exist there.
