How Does a Parachute Work in Theory
Throw a ball up in the air and, sooner or later, it always falls back to the ground. That's because Earth pulls everything toward it with a force called gravity. You've probably learned in school that the strength of Earth's gravity is roughly the same all over the world (it does vary a little bit, but not that much) and that if you drop a heavy stone and a light feather from the top of a skyscraper, gravity pulls them toward the ground at exactly the same rate.
If there were no air, the feather and the stone would hit the ground at the same time. In practice, the stone reaches the ground much faster, not because it weighs more but because the feather fans out and catches in the air as it falls. Air resistance (also called drag) slows it down.

A Study of 110,000 Sports Jumps

URL: (Source is below)

Date Accessed:2000-2016
A study was undertaken to examine the type, location, incidence and mechanism of injury sustained by amateur parachutists
in Denmark during a five-year-period. A total of 110,000 parachute jumps resulted in six (0.005%) fatalities and 155 (0.14%)
cases, requiring medical treatment. The latter group sustained 176 injuries of which 36.9% were significant soft tissue lesions
and 63.1% fractures. Landing is the most dangerous part of the parachuting procedure, causing 83.8% of the accidents, while
9.3% were caused by faults during opening of the parachute. Based on the injury...

Vehicle Safety Enhancement Essay

2136 words - 9 pages trying to develop airbags that stops the car during an emergency. Currently, we have many types of airbags that cushions our body during a car collision to cause minimal injuries. This is due to the small impulsive force exerted on our body. As the airbags cushions, it increases the time of impact which inversely decreases the impulsive force. Hence, less or sometimes no injuries to our body. At present, Swedish giants Volvo who are well-known for

Materials and Automotive Bumper Industry

899 words - 4 pages 1) What is a bumper?A bumper is a shield made of steel, aluminium, rubber, or plastic that is mounted on the front and rear of a passenger car. When a low speed collision occurs, the bumper system absorbs the shock to prevent or reduce damage to the car. Some bumpers use energy absorbers or brackets and others are made with a foam cushioning material.http://www.nhtsa.dot.gov/cars/problems/studies/Bumper/Index.htmlBumper systems have changed

Many bridge failures caused by fire today are usually man inflicted with things such as car crashes and gasoline fueled fires. These are still classified as man-made disasters. Examples of this occurred in 2009 semi-trucker on I-75 near Detroit suddenly burst into flames
