What determines the weight on planets?

A planet's rotation on its axis determines the length of its day.

Its carret, it determines the weight of the jewel just as in kg.

Because gravities are different on other planets which will affect your weight.

The mass and diameter of the planet.

the way the ocean spins in its sand

Your height and weight determines that.

Your weight changes. Relatively your weight increase on planets bigger than Earth and your weight usually decreases on planets smaller than Earth.

Some planets have less gravity or more gravity.More gravity giving you more weight and less giving you less weight.

The weight of the volcano.

Mercury and Mars have nearly identical gravities, and as a result, your weight would be similar on both planets.

It is weight changes depending on gravity. Weight can change. The pull of gravity determines an objects weight.

Yes, indeed. Everthing has weight but when you go to different planets, you weight changes.

The atomic weight determines the isotope, which is determine by the number of neutrons. (This answer was previously given to answer the question: "How do you determine the isotope")

The law of gravity. The gravity of the Sun pulls the planets to it. Also, the momentum (speed) of the planets also determines how far the planet orbits the Sun.

your mass is the same, but your weight depends on gravity.
