If it were not for air resistance how fast would raindrops fall?

Answer: Ignoring air resistance, we know that the speed of a free-falling object is given by: change in speed = (accelearation due to gravity) × (time of fall) and that the distance fallen by an object dropped from rest is given by: distance fallen = 1 2 × (accelearation due to gravity) × (time of fall)2 To solve this problem, we only know the distance fallen. From this, we can figure out the time of the fall, and from that we can figure out the change in speed (starting from zero speed, the change in speed will be the final speed). Putting in 1,000 m in for the distance fallen and 10 m/s2 in for the acceleration due to gravity, and calling the time of the free-fall t, we have: 1, 000 m = 1 2 × (10 m/s2) × t2

∙ 14y agoWithout air resistance, raindrops would fall with exactly the same characteristics as rocks ...
their speed would increase 9.8 meters (32.2 feet) for every second of falling.
(Of course, without air, raindrops would instantly evaporate; but you get the idea.)

How fast will a 2-kg ball fall from 2 meters high?
It will fall just as fast as an object of any other mass - assuming that air resistance is negligible. That is to say, if an object has a lot of surface area, it will fall slower due to air resistance.
How does air resistance affect how fast things fall?
Air resistance is basically friction between the object on the air- it has to push the air out of the way, and slows down.
Mt Everest is more than 8000 m high How fast would an object be moving if it could free fall to sea level after being released from an 8000-m elevation Ignore air resistance?
396m/s
Which would experience more air resistance -a streamlined car travelling slowly or a lorry travelling fast?
A lorry travelling fast.
Why is gravity a bigger force than air resistance?
It isn't, necessarily. But the force of gravity is constant, whereas the force of air resistance depends on how fast you're moving through the air. So when you begin to fall, gravity is stronger, and it makes you fall faster and faster. But as your speed increases, so does the force of air resistance, and eventually, the force of air resistance builds up to be equal to the force of gravity. At that point, you keeep falling, but your speed doesn't grow any more.
How fast do feathers fall?
All objects fall at a rate of 9.8 meters per second, or, 23 miles per hour. However, this is how fast they would fall in a vacuum, which is hardly ever the case on earth. To find out their true speed, you would have to minus the air resistance as well.

If it were not for air resistance why would it be dangerous to go outdoors on rainy days?
Possibly one for the physicists. But I think air resistance has nothing to do with it. I think gravity is what saves us. If you look at liquids in a weightless environment (there is air resistance)it just floats around, which means it can easily be inhaled and you would drwon. Air resistance prevents a falling object from reaching the full speed produced by the acceleration of gravity. It keeps falling raindrops from reaching bulletlike speeds. If air resistance were not present, raindrops would gain 10 meters per second of speed for every second of their freefall and thus reach the ground at dangerously high speeds�perhaps fast enough to puncture your skin. Not true, "The more compact and dense the object, the higher its terminal velocity will be. Typical examples are the following: raindrop, 25 ft/s, human being, 250 ft/s." I hardly think a raindrop falling at 25 feet per second is going to do much damage. Answer #2 is true. There is no "terminal velocity" without air resistance. Terminal velocity occurs when the force of air resistance is balanced against gravitational accelleration. The object continues to fall but at a fixed speed. Without air resistance, the object will fall faster and faster without bounds until a dangerous velocity is reached.
How fast in miles per hour would an object fall after 3 seconds?
At the end of 3 seconds, a falling object is falling at 65.8 mph faster than when it was released, ignoring air resistance.

An object that falls twice as far will be moving twice as fast when it hits the ground?
No all objects fall at the same speed, unless air resistance is involved
How fast would you fall if you were next to the sun?
You would first burn to death long ago and be part of the sun. Still, you would fall fast enough that you would be crushed to death if it had a hard surface and wasn't 10,000 degrees F at the surface.
