DB said:If gravity aplies the same force on every object, accellerating it to about 10 m/s2 (gee), then how come for example helium floats up to the sky?
Thnx

Gravity is the force that pulls objects towards each other. In the case of helium, which is a gas, gravity does not affect it as much as it does solid objects. This is because helium has a much lower density than air, causing it to rise and float upwards.
Helium is less dense than air, meaning that it has a lower mass per unit volume. This makes it less affected by gravity and allows it to rise and float upwards. In other words, helium is lighter than the surrounding air, so it naturally moves upwards.
No, there are other gases that also float up, such as hydrogen and methane. These gases have lower densities than air, just like helium, which allows them to rise and float upwards.
Yes, helium will float up in any environment where it is not contained or confined. This is because it is lighter than the surrounding air, causing it to rise and disperse into the atmosphere.
Helium is commonly used to fill balloons because it is less dense than air, causing the balloon to float upwards. As the helium gas is released from the balloon, it will rise and disperse into the atmosphere, causing the balloon to gradually lose its lift and fall back to the ground.
