You weigh less during a ful moon?

Answer 1

The reason that you would weigh less on the moon is that the moon's gravitational force is less than that of Earth. The law of gravity dictates that all bodies of matter attract each other with a force proportional to their mass. The moon's mass is only about 1/6 that of Earth, so gravity's pull is proportionally weaker as a result.

Note that your mass would not change, only your weight, which is purely a function of the force of gravity. If you were to run into a wall on the moon, it would be no different than hitting the same wall on earth, as your mass (and therefore inertia) still result in the same force of impact.

Answer 2

There is less gravity on the moon to pull you towards its surface than here on earth. Your mass x gravity(acceleration) = your weight. There is less gravity because the moon has less mass than the earth. All objects with mass have some amount of gravity that pulls them toward other objects with mass. The more mass you have in one spot the greater the pull of gravity there.

Answer 3

Weight occurs because mass is attracted to mass! Gravity is the name of the

force that attracts masses to each other. The strength of the force depends on

both masses. You have mass and the Earth has mass. Your weight is a measure

of the force between the Earth's mass and your mass.

Earth has about 81 times the mass of the Moon.

The strength of gravity at the surface also depends on the distance to the center of mass. The Moon is smaller than Earth, so that increases the surface gravity compared with Earth.

So, the two things work in opposite ways, but the effect of the Moon's smaller mass is by far the most important.

The result is that the surface gravity on the Moon is only about 1/6th that of Earth and you weigh about 1/6th of your Earth weight.

You weigh less on the Moon because the Moon's mass is less.

So the force between your mass and the Moon's mass is less.

Isaac newton worked out the gravitational equation that lets you calculate the

attraction between two masses.

Answer 4

Your weight on the moon is a function of the moon's gravity. First, we know that gravity is a force that attracts all physical objects towards each other (but why this happens is largely unknown!). Second, the greater the mass of an object, the stronger the force of gravity. 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. Finally, "weight" is a measure of the gravitational pull between two objects. So of course you would weigh much less on the moon.

Answer 5

The Moon has less mass. On the Moon's surface, the value of acceleration due to gravity is approximately equal to one-sixth that value on Earth.

The gravitational acceleration at Earth's surface (g) is 9.8 meters/second squared (m/sec2).

The gravitational acceleration at Moon's surface (g) is 1.6 meters/second squared (m/sec2).

Even though the Moon's mass is only about 1/80th the mass of Earth, the surface is much closer to the center of mass, yielding a higher effective gravity.

Answer 6

In the moon, we weigh less because the moon has less gravity than Earth. Weight is the product of the mass of a body and of the gravity (W=mg), so if the gravity is less, then the weight will be less. The only thing that does not change is the mass because it is a measurement of the amount of matter, whereas the weight is a measurement in relation to the force exerted by one body on another.

Answer 7

Because your weight depends on the mass of whatever other body is near you,

and your distance from it.

The moon has much less mass than the earth has, so the force between you

and the moon when you're on it is much less than the force between you and

the earth when you're on it.

Answer 8

No. The moon does have some gravitational pull, but not enough to pull you off the earth that much. The 'fullness' of the moon is also dependant only on the sun- when the moon is half full, you are seeing both sides of the moon, the one that faces the sun and the one that doesn't. If you see a full moon, it is no different than seeing a sliver of the moon or anywhere in between. The moon is always there, but the light shining on it changes.

Answer 9

Theoretically, you might weigh less if the moon was directly above you because of gravitational forces. The earth is pulling you down, making you weigh more; while the moon is pulling you up to make you weigh less.

Here's the theoretical physics:

• Your weight on the earth's surface is given by Fearth = G * myou * mearth / R2
• The force of the moon pulling up if it's right above you is Fmoon = G * myou * 0.0123 * mearth / (59R)2
• Fmoon=0.0123 / 59R2 * Fearth = About three parts in one million of your "regular" weight

NOTES:

F = weight [force expressed in Newtons (N)]

m = mass in kilograms (kg)

R = distance in metres (m)

G = constant with units (kg-1 m s3)

Answer 10

Because there is no gravity to secure you to the earth your weight is lower
