The mass of a 20 kg object is the same anywhere in the universe. That's its mass. Changing the gravity in which the mass is placed won't change the mass itself.
If you are interested in the weight, the 20 kg weight of the object on earth will show up as a 3.3 kg weight on the moon. (Kilogram can be used to measure both mass and weight)
edit 1: 'Mass' and 'weight' are different. Weight (w) is equal to the mass (m) of an object multiplied by the gravitational pull (g) exerted on that object; ie: w=mg
Mass looks at how 'heavy' something is without taking gravity into consideration
According to Newton's Third Law of Motion, the Law of Action and Reaction, if the Earth exerts a force on the Moon, the Moon must exert an equal and opposite force on the Earth.
Newton's Law of Gravity implies the same thing, as its mathematical formula,
F = G m M / r2,
in which F is the gravitational force between the two bodies, m and M are their masses, and r is the distance between them, yields the same value regardless of which object is thought of as pulling on the other.
m is the mass of Moon = 7.35 *1022 kg
M is the mass of Earth = 5.97*1024 kg
r is the distance between moon and earth: 384,000,000 meters
G is the gravitational constant, used in calculation of the gravitational attraction between objects with mass = 6.67 × 10-11 m3/kgs2.
Therefore, F is 1.985 x 1020 Newtons of attractive force between the Earth and the Moon.
In other words, both Laws say that the force the Earth exerts on the Moon is numerically identical to the force the Moon exerts on the Earth.
The only difference is that the Moon pulls the Earth toward the Moon, while the Earth pulls the Moon toward the Earth -- that is, the force on each object is toward the other object, and therefore in the opposite direction.
The weight of any object on the surface of the moon
is 16.55% of its weight on the surface of the Earth.
No, the Earth's gravity pulls the moon in towards Earth.
the moon because it has only one sixth of the gravitational pull that Earth does
The surface gravity on Io is very low compared to Earth, due to its low mass, around 0.183g or 18.3% of the Earths pull at the surface. this is just a little more than the surface gravity on our own moon, which is about 16.5% of earths pull.
If it were not for the Earth's pull of gravity the moon would fly away from the Earth. The moon's pull of gravity on the Earth causes the tides.
The Earth's gravity pulls the Moon towards it and its center.
The moon has it's own gravitational pull. The earth's gravity keeps the moon in orbit, while the moon's gravity tugs on the earth. This pull from the moon creates a bulge on the earth, especially on the oceans. This pull is what causes the tides to change.
Earth has a stronger pull than the moon.
At their respective surfaces, the acceleration of gravity, and therefore theweight of each unit mass, is 2.28 times as great on Mercury compared toits value on the moon. The moon's is 43.9% as great compared to Mercury's.Mercury . . . 3.697 m/s2 . . . 37.7% compared to EarthMoon . . . 1.623 m/s2 . . . 16.55% compared to Earth
If compared to earth, mercury has little gravity pull as its mass is much less than earth's mass.
yes, earths gravitational pull is strong enough to pull the moon into orbit around it.
Everything that has mass has gravity, even you. The Moon has its own gravitational pull as does the Earth.
The pull of the moon's gravity causes Earth's tides.
