How much would you weigh on a new planet when the gravity is 15 times as strong as the gravity on earth and you weighed 100 pounds on earth?

It depends what you mean by weight.
When we speak, we erroneously use the word weight for describing mass. The mass (or inertial mass in this case) is the measure of an object's resistance to acceleration and its unit is kilograms. The mass is an intrinsic propriety of an object which never changes. Hence, your mass is always the same, it does not matter where you are.
When we talk about weight we talk about the gravitational force which every object with mass is subject to. The weight takes into account the acceleration derived from the gravitational pull of any given body.
The wight is measured in Newtons and it is calculated by multiplying the mass by the acceleration derived from the gravitational field:
w=mg
The unit for weight is Newtons. The acceleration g on earth is approximately 9.8 m s-2 . This value is related to the mass of the object which creates the gravitational field.
In other words, your weight (expressed in Newtons) depends on the environment.
An object whose mass is 100 Kilograms weights on earth approximately 980 Newtons (w=100 Kg X 9.8 m s-2). If we move the same object to this new planet, on which the gravitational field is 15 times the terrestrial gravitational field its mass will still be 100 Kg but its weight will increase dramatically to 14,700 Newtons (w=100 Kg x 147 m s-2).
As for the the 100 pound object described in the question, we have to convert first pounds into kilograms and then we can calculate its weight on this new planet as well:
100 pounds= approx. 45 Kilograms
On the new planet its mass will still be 45 Kilograms (exactly as on earth).
Its weight on earth is 441 Newtons (w= 45 Kg X 9.8 m s-2).
Its weight on the new planet will be 6,615 Newtons (w= 45 Kg X 147 m s-2).
If we want to use English engineering units and we accept 100 pounds as a measure of mass we can simply say that the 100 pound object would wight 1,500 pounds-force on the new planet.

If someone weighed 100 pounds on Earth what would they weigh on Jupiter?
The gravity on Jupiter is 2.528 times as strong as on Earth, so a 100 pound person would weigh 252.8 pounds on Jupiter.If you weighed 100 lbs. on Earth you would weigh 32.854 lbs.
How strong is the gravity on Gliese 581c?
If it is a rocky planet with a large iron core, Gliese 581c has a radius approximately 50% larger than that of Earth. Gravity on such a planet's surface would be approximately 2.24 times as strong as on Earth. If Gliese 581 c is an icy and/or watery planet, its radius would be less than 2 times that of Earth, even with a very large outer hydrosphere. Gravity on the surface of such an icy and/or watery planet would be at least 1.25 times as strong as on Earth.
Why is planet near the sun has move very fast?
Near the Sun the force of gravity is very strong so the planet has more energy which means it has to move faster.
Why do objects weigh less on the moon than they do on the earth?
Gravity is strong here. It is the same reason we are held down on the planet
Is mercury a strong planet or a weak planet?
it is strong
If someone weighed 100 pounds on Earth what would they weigh on Jupiter?
The gravity on Jupiter is 2.528 times as strong as on Earth, so a 100 pound person would weigh 252.8 pounds on Jupiter.If you weighed 100 lbs. on Earth you would weigh 32.854 lbs.
What planet is giant with strong gravity?
Well if you're speaking about our solar system, Jupiter is the biggest giant planet with strongest gravity.
Does the planet with the most moons get the strongest gravity?
In our solar system, at least, the planet with the greatest mass does happen to be the one with the most known moons. But I think the cause and effect work the other way. It's not the moons that give the planet strong gravity. It's the strong gravity of the planet that captures a bunch of moons.
What makes a planet have weak gravity?
Big planets has a strong gravity. In small planets it's opposite
Can a dwarf planet be round?
Yes their gravity if strong enough will make them round.
How strong is Neptune's magnetic field?
The force of gravity on the surface of planet Neptune, and all of the other gas giants, is surprisingly weak, because most of it is not made of solid material. Neptune's force of gravity is about 1.14 times that of Earth. If you weighed 100 pounds and if you could stand on the surface of Neptune (which you couldn't), you would weigh 114 pounds.
How strong is gravity on each planet?
pretty cool when u go up and down
Can a planet collapse under its own gravity?
No, a planet does not collapse because gravity isn't strong enough to provide enough pressure to crush a planet. You might make a planet heavier and heavier as to increase its gravity but at some point the pressure in the planet's core will be high enough to support nuclear fusion and the planet will have changed into a star. At that point radiative pressure also begins to fight gravity.
Could you fly off of a planet because there is no gravity?
No. All planets have gravity. Any object massive enough to be considered a planet would have strong enough gravity that you could simply escape by jumping. It is, however, possible for an object to escape the gravity of any planet if it is launched in the right way and with enough speed.
One theory about asteroids says that Jupiter's strong what prevented the asteroids from forming a planet?
gravity
How much would a 100 lb person weigh on a planet twice the mass of earth?
That would depend on the planet's radius. The strength of gravity depends on both the mass of the object in question and the distance from its center of mass. If the planet in question had the same radius as Earth, then the person would weigh 200 lbs as gravity would be twice as strong. If the planet had the same density as Earth it would have 1.26 times Earth's radius and gravity would be 1.26 times as strong and the person would weigh 126 lbs. If the planet had about 1.41 times Earth's radius then that person's would weight 100 lbs.
How strong is the gravity on Mars compared to earths?
it is 38% of earths gravity. Fun fact- Jupiter is the biggest planet in the solar system YAY
