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

An object's weight depends on the gravitational force acting on it. This force is determined by the mass of the object and the mass of the celestial body it is near, following Newton's law of universal gravitation.

Answer 6

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

Answer 7

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

nearby object, and the distance between their centers.
