The weight of a human on the Earth is unaffected by the Moon's gravity, because the Moon is so far away. Even if the Moon were much closer, the effect on people would be insignificant.
If the Moon were VERY close - a few thousand miles, perhaps, the direct effect of the Moon's gravity on people would still be trivial, but the effect of the Moon's gravity on the Earth would probably be devastating. We might expect every earthquake fault in the world to let loose, and the tides would be high enough to swamp coastal cities. (With New Orleans being below sea level anyway, we could say goodbye to the Big Easy.)
The reason that the effect of Moon's gravity would be tiny even with the Moon at 3000 miles is that the force of gravity decreases with the square of the distance. The Moon is only just over 1,000 miles in radius. If the Moon were 3000 miles away from Earth, then people would be 4,000 miles from the center of the Moon - 4 times further than they would be ON the Moon. 4 times further away means that the force of gravity would be 1/16th of normal, and the Moon's gravity is already very low compared to Earth; about 1/6th Earth-normal. So the gravitational effect on a human of the Moon being 3,000 miles away would be about one one-hundredth of the Earth's gravitational force.
As I said - an insignificant difference.

∙ 13y agoIf you were on the moon, the weight that was measured when you were on earth
wouldn't change. But if you brought a bathroom scale to the moon with you and
weighed yourself there, the number it displayed would be only about 16 percent
of your earthly weight.

What if the moon was not in orbit of the earth?
If the moon was not in orbit around the Earth, the tilt of the Earth's axis with respect to the plane of the ecliptic would be unstable. As a result, seasons and climate would be unstable, and life as we know it on Earth would change or disappear.
How would the appearance of Earth change if you watched it from the near side of the Moon for a month?
The Earth would appear to go through the same phases that we see in the Moon, except that the Earth would appear to be almost stationary in the sky; it would wiggle a little.
Draw a free body diagram for the moon?
If you mean the Moon's movement around the Earth, the Earth's gravitation pulls the Moon towards the Earth. There is no opposing force that acts on the Moon (otherwise, the Moon wouldn't accelerate towards the Earth, i.e., change its direction).
Where would an astronaut weigh the most the moon or earth?
Earth because on the moon you would weigh one sixth
What would be the affect of the Moon's and sun's gravitational pull on earth?
The Moon would continue to orbit the Sun, possibly in a different orbit. Assuming the Moon kept its (Earth) orbital velocity, this would cause it to move either slightly closer or slightly farther from the Sun. The Moon's relative velocity to the Earth is about 1 km/sec whereas the Earth-Moon system orbits the Sun at 30 km/sec. The sudden disappearance of the Earth would mean the continuation of the Moon's solar orbit, albeit possibly altered.
If you put a moon rock on the earth would the weight of the rock change?
Yes. On Earth rock would weigh about six times what it does on the moon. The mass however will not change.
What is the amount of matter that an object has if the object were on the moon this would not change?
That is its mass which does not change on earth, moon, or anywhere.
How would the mass of an object change if it were on the moon?
The mass of an object itself does not change on the moon. However, an object's weight is less than it would be on Earth because the moon's gravity is weaker than Earth's gravity.
What property would change if a man were to stand on the moon of earth?
His weight would be approx 1/6 of his weight on earth.
Would nutation change if there were no moon?
Yes. The Moon is a major cause of the nutations of the planet Earth.
If oranges weigh 16.7 newtons on earth what would their weight change be on the moon?
on the moon it will weigh roughly 1/6 the amount of newtons as it does on earth. So 16.7 on earth would be about 2.8 newtons on the moon.
Why would the motion of the moon change if the mass of the earth increase?
The motion of the Moon would change if the mass of Earth increased, because the Earth's gravity would increase. The change in the gravitational force between Earth and Moon would affect the orbital path of the Moon. More details, if wanted: The Moon would be pulled towards the Earth. It's possible that the Moon would collide with Earth, depending on the strength of the Earth's new gravity. The other possibility is that the Moon would simply go into a new, more elliptical, orbital path. The Moon's speed would be greater than before at its closest approach to Earth. Its orbital speed at its furthest point would be similar to its original speed. I think that's right. I've checked my answer with a website, but I haven't seen any mathematics on the problem.
If you weigh 100kg and went to the moon which has 16 the gravity of earth would your weight change?
yes it would change
What if the moon was not in orbit of the earth?
If the moon was not in orbit around the Earth, the tilt of the Earth's axis with respect to the plane of the ecliptic would be unstable. As a result, seasons and climate would be unstable, and life as we know it on Earth would change or disappear.
Would an object weigh more on the earth or the moon?
The planet Earth has more gravitation pull than its moon. Therefore the weight on earth is more than that on the moon. The mass though does not change.
If you weigh 50 kg on earth what is your mass on the moon?
The same as it is on the Earth. Mass does not change, weight does.If you weighed 50kg on Earth you would weigh about 8.3kg on the Moon.
What is the mass of a 30N chicken on the moon?
The mass will not change. Its weight measured on the Moon would be 1/6th of what it is on Earth.
