Does the moon have a low or high gravity?

Answer 1

The gravity of the Moon is 1.622 m/s2 (0.165 4 g)

For comparison, the Earths gravity is 9.780327 m/s2 (0.99732 g)

So the Moon has about 1/6th the gravity of the Earth.
The acceleration of gravity on the moon's surface is 1.623 meters per second2.

That's 16.55% of what it is on the Earth's surface.

If you weigh 200 pounds on Earth, you'd weigh 33.1 pounds on the moon.

Answer 2

Gravity is exactly the same on the moon as it is on Earth or anywhere else. No

matter where you observe it, two objects are always gravitationally attracted

to each other by a pair of equal forces that are proportional to the product of

the masses and inversely proportional to the square of the distance between

their centers.

The effect of the moon's smaller size and much smaller mass compared to the

Earth is that the gravitational forces between the moon and a test mass on its

surface are about 16% of the forces between the Earth and the same test mass

on its surface.

Here are some of the noticeable effects of gravity on the moon:

-- There is a force on everything that tries to pull it down.

("Down" is a short word for "toward the center of the moon".)

-- When you drop something, it falls down.

-- When something is falling, it goes faster and faster.

-- When you toss something up, it goes up slower and slower,

then it stops going up, and begins to fall down.

-- What goes up must come down, unless it has rocket engines on it.

Answer 3

The moon is 1/4 the size of Earth, so the moon's gravity is much less than the earth's gravity, 83.3% (or 5/6) less to be exact. You can find out more about this at: http://www.moonconnection.com/moon_gravity.phtml

Answer 4

For any spherical object, half of it will be in sunlight. (Unless it is in eclipse.)

So half of the Moon is in in sunlight. As the Moon orbits the Earth, we can see varying portions of the sunlit half; this is what causes the phases of the Moon. During a New Moon, the far side of the Moon is bright, while the nearside is dark. At the Full Moon, the farside is dar while the near side is light.

Answer 5

Great question. Let's work it out:

Mutual force of gravitation between 2 masses is:

-- proportional to the product of the masses, and

-- inversely proportional to the square of the distance between them.

Here's the data:

Mass:

Sun: 1.98 x 1030 kg

Earth: 5.97 x 1024 kg

Ratio: 3.32 x 105

Distance from moon:

Sun: 9.3 x 107 mi

Earth: 2.39 x 105 mi

Ratio: 389.4

Square of ratio: 151,598

Ratio of the forces = (3.32 x 105) / (151,598) = 2.19

There you have it. There are mutual gravitational forces of attraction between a piece of mass

on/at the moon and both the earth and the sun. The force toward the sun is the greater one,

by about 2 to 1.

To put a finer point on it, you are an astronaut who weighs 220 pounds on earth. When you

stand on the moon, the mutual gravitational forces between you and the Big-3 are:

Moon: 35.9 pounds

Earth: 1 ounce

Sun: 2.1 ounces

Answer 6

Specific gravity cannot be used in this context.

Specific gravity is the ratio of the density (mass of a unit volume) of a substance to the density (mass of the same unit volume) of a reference substance.

See related question for the gravity of the Moon.

Answer 7

The force of gravity for a person on the Moon is about one-sixth that of a person on Earth.

Answer 8

The Moon's gravity is about 1/6 th that of Earth.

Answer 9

0.1654g, or about 16.54% of Earths (roughly one sixth).

Answer 10

The same sort of gravity every other planet, asteroid or moon has.
