No. The gravity at Neptune's nominal "surface" is only about 14% greater than it is on Earth. If you had a platform you would be able to stand without much difficulty.
You would freeze to death, or be squashed flat by the tremendous increase in gravity, or asphyxiate because of the methane/ammonia atmosphere. It's merely a matter of which would happen first. No Club Med, in other words.
yes
No. The 'surface' gravity of neptune is only 1.14g, due to the low density of the planet. Surface pressure may 'squash' a person there though, although they would be frozen from the near 0K temprature. (approx -218C)
yes
No. Neptune has an atmosphere made mostly of hydrogen and helium. While this atmosphere would cause asphyxiation, a person would not choke. Regardless, Neptune is so cold than a person would freeze to death before they could asphyxiate.
Mars does not have extreme gravity! It is less than 40% of the earth's gravity.
A 20.0 kg dog on Earth would weigh about 6.36 kg on Neptune. This is because Neptune's gravity is about 11.15 m/s², which is 1.14 times stronger than Earth's gravity.
No, because of the great volume the gravity on Neptun is barely stronger than on the Earth.
Neptune's gravity is 1.14 times the earths gravity. So if you weigh 100 pounds you would weigh 114 on Neptune.
To answer this we must start by taking a look at Neptune's mass. Neptune's mass is about 1.02 x 1026 kg. It would take over 17 Earths to fill up Neptune, but the gravity on Neptune is only 1.19 times of the gravity on Earth. This is because it is such a large planet (and the gravitational force a planet exerts upon an object at the planet's surface is proportional to its mass and to the inverse of its radius squared). A 100-pound person would weigh 112.5 pounds on Neptune. If the object is massive it will gain gravity but if it is large it will lose gravity at a greater rate.

On Uranus, you would choke, be squashed, and burn up.
