What does an objects weight depend on in the universe?

Answer 1

Weight is dependant on the mass of the object and the gravitational force of the nearest massive body (usually a planet, moon, star or black hole), also dictated by it's mass.

Also your distance from the center of that body, you weigh less the higher up on a mountain you get, for instance.

Answer 2

It depends on the Gravitational force of the planet or moon that it is on. 100 pounds on Earth weighs 100 pounds but on the Moon it weighs 6 times less as the Gravity of the moon is 1/6th that of Earth, so it would be 16.66r pounds on the Moon.

Answer 3

ans:

direction:

look up all the planets in the solar system on wiki in turn. Then divide their mass by their volume.

let me see... GmM / r^2

take out G and m and you have M/r^2

vol = 4/3(pi)r^3

r = (vol.(3/4).(pi))^(1/3)

G and m are common to all planets, so can use only M/r^2

if they tell you radius of planets, don't bother with vol and work from that, as it will save time!

so, M/r^2 where M= mass of planet and r = radius of planet.

if M/r^2 is big, then force due to grav on m (object on surface) is the greatest.

Answer 4

I don't see a question there, so I'll just offer a comment on the statement:

An object's mass doesn't depend on its location at all ... an inconvenient fact

that renders the statement false.

Answer 5

Both its mass and the force of gravity acting on it.

Answer 6

An object's weight depends on its mass, the mass of any other

nearby object, and the distance between their centers.
