In the absence of air, all objects fall with the same acceleration. That means that at the same time after the drop, all objects are moving at the same speed.
Yes. But not if there is a difference in air resistence.
then we wouldn't be able to identify from air and glass at all, since light would pass through glass without deflecting at all!!
if all of the forces affecting the objects are the same, then yes (i.e air resistance to a feather).
because of the differences in air resistance.
The temperature and moisture characteristics are uniform in the same air mass.
With the same acceleration.
if it is an air plant then all it needs is air. if it is an air plant then all it needs is air. BUT OTHER PLANTS NEED AIR JUST THE SAME
One would be the air having 100% relative humidity, meaning all the air is at the same temperature.
All air has mass. Warm air of the same volume as cold air will have a lower mass.
In a vacuum they all fall at the same speed, but in air, air resistance slows them all. Some more than oyhers. Density has an effect, but so does shape.
air ,planet, cycle
Neglecting air resistance ... all of them.
The same for all.
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.
Gravity causes all objects to accelerate at the same rate in a vacuum. In air there is air resistance which can slow some objects down eg a parachute. So, yes, in a vacuum all objects reach the same speed in the same time period.
Is air on the same level is a question with too little information. Air is all around, surrounding everything. The air could be considered on the same level of the people and the land due to it's existence. If the question is referring to air being compared to another substance, compound, or item.
