On Earth, gravity is 10 newtons per kg, or 10n/kg. Newtons are used to measure force, and kilograms are used to measure mass, a common misconception that kg's are used to measure wieght.
Wow, the upthrust of the rocket is larger than the force of gravity and air resistance! This enables the rocket to fly.
Cool, my mass of 57kg stays the same, but my weight has dropped because on the moon, 1kg equals to 1.6 newtons.
The rocket on Jupiter is sinking into the ground and getting crushed, since Jupiter is a gas giant and has a gravity 2.5 times higher than Earth, or 24.79 Newtons per kg. In this case, the force of lift is much smaller than the force of gravity, so you would sink into the centre of the planet.
Mars has a gravity that is 3.7 Newtons per kg, less than half of Earth's. People also believe that Mars is the planet that is capable enough for humans to live on, even though 95% of its atmosphere is made of nitrogen.
If a planet has a larger mass, it exerts a stronger gravitational pull, so Jupiter will obviously exert the strongest gravitational pull. Luckily, we will not be sucked into the centre of Earth, because Earth exerts a weaker pull than Jupiter. Ulike Jupiter, the force of lift is equivalent to the force of gravity.
