Mass itself doesn't actually change gravity (on a notable scale, unless their is a whole lot of mass, like a planet), but rather the amount of mass affects, how gravity will effect it. Technically, all objects have gravity, but most aren't noticeable. But, to answer the question mass does "change gravity" dramatically, for example if you have a human and a plant, obviously the plant has more mass, so the human is drawn to the plant, But, if you have to human next to each other their will be no noticeable gravitational pull, so clearly mass has a great effect on gravity.
when doing physics problems gravity is replaced by 3.14
Gravity isn't heavy - it makes things heavy but only when opposed.
How powerful is it?
It holds the galaxy together, perhaps the whole universe.
how much you weigh depends on the pull gravity has on you.
Weight = mass x gravity. Therefore, this will happen as long as gravity doesn't change.
If you mean what is gravity then it's the characteristic of space that causes a pair of forces between you and center of a planet, for example earth. this is what causes how much you weigh, which is also why you weigh less on the moon.
"The force of attraction by which terrestrial bodies tend to fall toward the center of the earth.How much you weigh on it
Nothing, the force of gravity is always the same no matter how much you weigh. It will only change if you go to another planet.
gravity
Depends on the weight of the desk. As weight = Mass * Gravity the table wouldn't weigh much on the moon as gravity is considerably less.
The moon's gravity is 1/6 th of Earth's gravity, so you would weigh 75 pounds.
The moon's gravity is 1/6 th of Earth's gravity, so you would weigh 75 pounds.
how much you weigh depends on the pull gravity has on you.
Anytime you are in a place with less gravity, you or any object will weigh less. The force of gravity on the moon is much less than on Earth.
it wont weigh anything because you are in space because of the gravity xxxx :)
the pull of gravity on matter
Not much, if you weigh 100lbs on Earth, you would weigh 37.7lbs on Mars.
Weight = mass x gravity. Therefore, this will happen as long as gravity doesn't change.
10 lbs
A 50-pound would approximately weigh 8.5 pounds on the moon. Moon's gravity is approximately 1/6 of the earth's gravity.
