no. Actually air exist on the surface of planets. It sticks to them because of gravitational force. there are no air particles in space. space is just nothing.
No. No air means no air resistance.
You can't fall in space, there is no gravity. An object will travel as fast as it is accelerated and continue at that speed forever as there is no air resistence to slow it down.
Gravity and air resistence.
In a vacuum sealed room, yes, they can. If not, then without properly balanced air resistence, no. The only reason objects fall at different speeds is because of air resistence/terminal velocity, things of that nature. When dealing with air, and etc... if you want them to fall at the same speed, they have to have the same air resistence (a combination of space taken up, and mass.) So yes, they could fall at the same speed, but the yarn would probably have to be coiled extremely tightly.
The air resistence have on air is for example when your are riding a bike, the air is pushin against you, so the air resistence is holding you back in speed. That's why when you see birds flying in the air, you see them flying in a triangle formation, they do that so the air resistence can fly past them easier.
A feather.
yes it does
yes, all the objects fall at same speed if we neglect air resistence but they appear to be falling at different speeds due to air resistence.
The primary force is air resistance, then there is friction and gravity.
Yes. But not if there is a difference in air resistence.
Gravity, Air resistence, friction and the push from the floor/table
gravity and air resistence. Gravity pulls the rocket down while air resistence pulls the rocket up
Air resistance depends on the velocity of the moving object.
