Why is the weight of an object on earth different from its weight on the moon is?

Answer 1

There are many differencese between the moon and earth. The biggest difference is that the moon has very low gravity. If you were on the moon, you would weigh 1/6 of what you weigh on earth. The reason the moon has such low gravity is because the moon has a very small mass. Mass affects gravity. To learn more about this, see Einstein's General Relativity. Because the moon has such low gavity, an atmosphere can't exist on the moon because there's nothing keeping it in place around the moon. Because there's no atmosphere, there is no erosion. That's why the moon is cratered, because about 4.4 billion years ago when the solar system was just forming, the moon got hit a lot by asteroids and smaller planets that don't exist anymore. Because there's no atmosphere, there's also no air friction, so if you drop a rock and a feather on the moon, they would fall at the same speed. There are many more differences, but you're probably getting bored by now. I hope this helped.

Answer 2

object will fall faster on earth, coz the gravitational pull is more on earth than moon.

gravitational pull is an acceleration, which means increase in velocity per second.

since velocity of falling object increases after every spent second,like velocity of falling object on earth increases by 9.8m/s after every second

more velocity means less time to travel distance. therefore object takes less time to fall on earth,than on moon

Answer 3

It's all to do with the size of the mass you are close to. Earth is relatively large and so has a fairly strong gravitational field when compared to the moon. The moons mass is smaller, so has a weaker gravitational field. In space, if there were no planets or massive objects about, then there would be no gravity and so you would experience weightlessness. It's a bit different with astronauts in orbit around the earth, the gravitational effect of the earth is still there, but the astronauts and their space vehicles all have an orbital velocity, so they all 'falling' at the same rate.

Answer 4

Too many unknown variables. If you mean to refer to acceleration due to the differences in gravity, rather than velocity, that would be a different question.

The moon's gravitational pull is about 16.7 percent of that on Earth, meaning things would only "weigh" 1/6 of what they do on earth, but they still have the same MASS regardless of where they are in the universe. Their speed upon impact would depend upon the forces applied over the time during motion.

Other possible variables include:

• whether the falling object would be affected by the presence of air friction on earth and no air friction on the moon;
• comparative buoyancy of the object in air versus vacuum;
• how far and how long the object has fallen and whether it has reached terminal velocity (or keeps accelerating in the moon's vacuum);
• which direction the object was moving when it started falling, such as an object being shot straight up would have twice the difference from an object simply falling from a fixed position (i.e., the deceleration at the top of the trajectory, plus the acceleration in the return).

Answer 5

there is more gravity on earth than the moon

Answer 6

Weight = mass x gravityThe mass of the same object, taken to the Moon, will basically not change.

The Moon's gravitational field, however, is less - about 1/6 that of the Earth.

Answer 7

There are other forces at work, the planet earth, is a conductor of magnetic forces that don't exist in outter space. The gravity exist because of the sun, in which, it's gravitational pull manages to hold all the planets in the solar system in orbit around the sun.
