What type of friction causes a sky diver's acceleration to change as he fall?
Wiki User
∙ 7y ago
A sky diver is falling through a Fluid with a measurable viscosity. The fluid is AIR. Pushing air molecules out of the way, and having them rub along the body of the skydiver's clothing causes friction (heat). This resulting friction on a human sized body results in a terminal velocity of approximately 124 MPH (200 KPH).

∙ 7y agoThe friction is the wind resistance the skydiver experiences during the free fall. If the body is held horizontal to the ground, arms and legs held out like a cross, the wind resistance increases and the body is slightly slower than if the skydiver turns vertical to the earth, as though diving off a diving board into a swimming pool. There is a terminal velocity of approximately 60 m/s for a typical skydiver in free fall.

Do sky divers go up when a parachute opens?
Sky divers do not go up, but they do undergo deceleration due to the increased drag incurred by the parachute being suddenly opened. Since skydivers, when being filmed by a cameraman, release their parachute first, there is a relative acceleration between the cameraman and the skydiver, creating the illusion that the skydiver is travelling up.
What is the acceleration of two falling sky divers mass 112.0 kg including parachute when the upward force of air resistance is equal to one-fourth of their weight?
If air resistance is 1/4 of the falling object's weight, then the net force on it ...(gravity + air resistance) ... is 3/4 of its weight downward. Its acceleration thenmust be 3/4 of the acceleration of gravity, or 7.36 meters (24.1 feet) per second2.The mass of the object, or how many of them there are, makes no difference.You took care of that when you said that the air resistance is 1/4 of its weight.

What causes pulmonary oxygen toxicity?
Pulmonary oxygen toxicity is caused by divers exposing themselves to elevated partial pressures of oxygen for long periods of time, and is primarily a concern for technical divers who decompress on oxygen. Pulmonary oxygen toxicity causes a burning sensation in the trachea, coughing, shortness of breath, and eventually lung failure.
What is the collective noun for divers?

What are three factors that made pearl diving so dangerous in the early 1900s?
Free divers risk the danger of drowning while underwater, especially in areas requiring divers to descend to extreme depths. All pearl divers risk encountering dangers under the water, including sharks and other sea life. Many Australian pearl divers perished during storms that claimed the pearling boats while the divers were still on the bottom. Beyond environmental hazards, pearl divers also have to cope with the "bends," a condition caused when rapid decompression from quick surface ascent causes nitrogen bubbles to form in the bloodstream.

How do you use dive in a sentence?
To use it in that form, you could use it as a command. For instance, Dive into the water. To use it in another way, you would have to change the verb tense to "dove" or "diving" or something else like that.
