Extremely Educational Explanation of Gravity – Gravity Visualized

Explanation of Gravity – To put gravity into Layman’s terms would require a simple explanation of gravity, with a visual explanation.

Actually, weight changes when the pull of gravity changes. The Moon is much smaller and the pull of gravity on the Moon is about 1/6th that of Earth. So any object on the Moon weighs 1/6th of its weight on Earth.

Every object in the universe that has mass exerts a gravitational pull, or force, on every other mass. The size of the pull depends on the masses of the objects. You exert a gravitational force on the people around you, but that force isn’t very strong, since people aren’t very massive. When you look at really large masses, like the Earth and Moon, the gravitational pull becomes very impressive.

The gravitational force between the Earth and the molecules of gas in the atmosphere is strong enough to hold the atmosphere close to our surface. Smaller planets, that have less mass, may not be able to hold an atmosphere.

Explanation of Gravity

Although many people had already noted that gravity exists, Newton was the first to develop a cohesive explanation for gravity, so we’ll start there.
