Free fall

In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it and moves along a geodesic. The present article only concerns itself with free fall in the Newtonian domain.

An object in the technical sense of free fall may not necessarily be falling down in the usual sense of the term. An object moving upwards would not normally be considered to be falling, but if it is subject to the force of gravity only, it is said to be in free fall. The moon is thus in free fall.

In a uniform gravitational field, in the absence of any other forces, gravitation acts on each part of the body equally and this is weightlessness, a condition that also occurs when the gravitational field is zero (such as when far away from any gravitating body). A body in free fall experiences "0 g".

The term "free fall" is often used more loosely than in the strict sense defined above. Thus, falling through an atmosphere without a deployed parachute, or lifting device, is also often referred to as free fall. The aerodynamic drag forces in such situations prevent them from producing full weightlessness, and thus a skydiver's "free fall" after reaching terminal velocity produces the sensation of the body's weight being supported on a cushion of air.

Red Bull

Red Bull is an energy drink sold by Austrian company Red Bull GmbH, created in 1987. In terms of market share, Red Bull is the highest-selling energy drink in the world, with 5.387 billion cans sold in 2013.

Austrian entrepreneur Dietrich Mateschitz was inspired by an existing energy drink named Krating Daeng, which was first invented and sold in Thailand. He took this idea, modified the ingredients to suit the tastes of Westerners, and, in partnership with Chaleo Yoovidhya, founded Red Bull GmbH in 1987 in Chakkapong, Thailand. In Thai, daeng means red, and krating is the large bovine called "gaur". Red Bull is sold in a tall and slim blue-silver can, while Krating Daeng is in a gold shorter can. The two are different products, produced separately.

The Red Bull company slogan is "Red Bull gives you wings", and the product is marketed through advertising, events (Red Bull Cliff Diving World Series, Red Bull Air Race, Red Bull Crashed Ice), sports team ownerships (RB Leipzig, FC Red Bull Salzburg, Red Bull Brasil, New York Red Bulls, Red Bull Racing, Scuderia Toro Rosso), celebrity endorsements, and music, through its record label Red Bull Records.

I-GO

I-GO was a Chicago-based car sharing organization owned by Enterprise Holdings. I-GO was established in 2002 by the Center for Neighborhood Technology as an independent 501(c)(3) not-for-profit organization dedicated to creating and implementing new strategies that make urban communities more livable and environmentally sustainable. I-GO was sold to Enterprise Holdings in May 2013 and re-branded as Enterprise CarShare.

Mission

I-GO’s mission was to reduce car ownership rates, decrease transportation costs, reduce urban congestion and improve air quality in Chicago. From its inception, I-GO worked to catalyze a set of transportation innovations that make it feasible and desirable for Chicago residents to get around conveniently and economically without having to own a car and, at the same time, reduce vehicle miles traveled and greenhouse gas emissions. By contributing to the environmental improvement of the Chicago area and the decrease in expenses for residents, I-GO's triple bottom line impact provided a significant social return on investment.
