False. Gravity on the moon is 1/6 that of Earth.
Gravity is determined by the mass of an object. An object with twice the mass will have twice the gravitational pull. Since the moon is much smaller (has a lot less mass) than earth, the gravity on the moon is less than on earth.
On Mars, there is low gravity, so there you could jump twice as high as you can on Earth. The acceleration due to gravity on mars is 3.71 m/s2, which is 0.379 times that of Earth. (The gravity on Earth is 2.64 times greater than the gravity on Mars.)
Jupiter and Neptune are the only planets in our Solar System that have more gravity than the Earth. Jupiter's gravity is about 236% that of the Earth, and Neptune's gravity is about 112% that of the Earth. Edit: Because of uncertainties and different definitions you can get data that says Saturn and/or Uranus also have slightly stronger gravity than Earth's.
Dan's mass is the same as it is on Earth. His weight, however, is doubled.
No. Let's take Earth as a good example to start with. Let's say you look at the force of gravity of Pluto if it were twice as far from the Sun as Earth is. The force of gravity would be 2x2 = 4 times weaker. Move Pluto away from Sun twice that distance, and the force of gravity would be another 4 times weaker. Move Pluto away from the Sun another 2 times its previous distance, and the force of gravity between it and the Sun would be yet another 4 times weaker. And so on, until you reach a point in space where Pluto is really, actually positioned.
Despite the fact that Uranus has a mass 14.5 times Earth's mass, its surface gravity isless thanEarth's.Jupiter and Neptune both have more "surface gravity" than Earth.
No. The gravity of Jupiter more than twice as strong as that on Earth.
Earth has the greater gravitational pull. Mars pulls with only about 38% of Earth's gravity.

If you mean more than Earth, it has more mass. Twice the mass will cause twice the amount of gravity (at the same distance).

Dan's mass is the same as it is on Earth. His weight, however, is doubled.
The formula that relates them is: weight = mass x gravity If gravity doesn't change - which is the usual case close to Earth's gravity - you can say that weight is proportional to mass. That means that twice the mass results in twice the weight.
a G is the force due to gravity. 2G would be twice the force due to gravity. Astronauts have to withstand multiple G when leaving the Earth's atmosphere.
The mass of the object would remain the same because mass is an intrinsic property of the object. However, the weight of the object would double on a planet with twice the gravity of Earth since weight is the force exerted on the object due to gravity, which is directly proportional to the acceleration due to gravity.
For sure. Mars has about twice the gravity of the Moon and the astronauts could walk there. Mars has about a third of the gravity of the Earth, so you could walk quite happily - albeit with a lot less effort.
