Why can't skydivers breathe?
They actually can breathe, though it is not "normal" because the air is rushing past them so fast. I never thought about my breathing when I was in freefall.
How fast does oil spread through the air?
Oil is not spread through air .
Is it conservation of mechanical energy when skydivers drop in the air at a constant rate and why?
No. In free fall, where mechanical energy is conserved, the falling object would go faster and faster. In this case, to fall at a constant speed, mechanical energy is lost, due to friction.
How fast does gravity pull you down?
If there were no air, then anything falling would fall 32 feet per second faster every second. But it takes energy to plow through the air, so the actual speed at which things fall through it depends on their shape, size, and weight. A skydiver can make himself fall faster or slower by changing the positions of his arms and legs.
Does water affect how fast something falls?
Yes, however, even air affects how fast something falls. The weight of the water is what causes buoyancy (certain materials to float), and and the resistance of water plays a small role - the weight of the water being the larger role - in what causes other materials to fall slower than they would through air. There are actually certain things that are buoyant in the air, like helium. You will notice that if you let all the air out of your lungs, you will fall down through the water at a certain (very slow) speed. That speed is your terminal velocity through water. The terminal velocity of an average sized human through the air is about 55.6 m/s (200 kph or 124 mph). This speed is obviously much higher than the speed at which something falls through water. So water does affect haw fast something falls. "But wait, certain objects appear to fall through the water at the same speed that they fall through the air!" To explain this, water affects how fast something falls - compared to how fast it falls through the air - depending on its density. The object which you're talking about, is actually falling slower through the water, you just can't tell. We see this property in air too, why do you think a pound of feathers falls much slower than a lead weight?
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.
What occurs when rock fragments fall freely through the air?
Free fall
What is the type of friction that occurs when objects fall through the air?
Air resistance is.
What is the force that slows a parachutist down as they fall through the air?
Air Resistance or friction with the air.
What is the force that slow a parachutist down a they fall through the air?
Air Resistance or friction with the air.
How does air 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.
How fast do objects fall through air?
An object's top speed is called Terminal Velocity.The terminal velocity of an object can be calculated via a formula. See the related links.
