Skydiving can be an exhilarating sport whether it is deadly or done correctly. Skydiving is the sport of jumping from an aircraft and performing acrobatic maneuvers in the air under free fall before landing on the ground with a parachute. As the skydiver falls‚ he or she encounters the force of air resistance. The amount of air resistance is dependent on two variables‚ speed and cross-sectional area. The speed of the skydiver accelerates downwards and gains speed with each second. The increase in

Kyle Tucker Aliens Take Over Mars English lll 14 December‚ 2012 I am sure we all have been wondering and heard on the news about the supposedly finding of earth on mars. There are always the people that find a way to make it not believable‚ but can they really prove that there is no life on mars? The NASA Mars rover‚ Curiosity‚ has found evidence that there could possibly be life on Mars. “Rumors are currently swirling after John Grotzinger‚ project scientist for the Curiosity rover

of drag is meant to take distinct gender norms‚ mix them into a blender‚ and produce a discussion‚ as well as visual display‚ of gender fluidity. Drag queens are meant to close the gender gap by advertising and supporting every degree of gender. A drag queen is usually explained as a man (usually gay) impersonating a woman‚ or several women‚ for the purpose of entertainment or performance. They can range from those who do it as a job to those who do it as a form of artistic expression. Drag shouldn’t

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. Examples of objects in

Fluid Mechanics 3-Aerofoil Lab Report Introduction This report aims to investigate the effect the angle of attack of an aerofoil has on the air flow around it. This was done by recording the lift and drag forces the aerofoil experienced when positioned at different angles of attack. The experimental lift force the aerofoil experienced when positioned at different angles of attack was then compared with theoretical values. An attempt was made to explain any discrepancies

Dimensional analysis of models and data sets James F. Pricea) Woods Hole Oceanographic Institution‚ Woods Hole‚ Massachusetts 02543 Received 22 May 2002; accepted 4 November 2002 Dimensional analysis is a widely applicable and sometimes very powerful technique that is demonstrated here in a study of the simple‚ viscous pendulum. The first and crucial step of dimensional analysis is to define a suitably idealized representation of a phenomenon by listing the relevant variables‚ called the physical

Drag racing is a test of speed. I’ve always been interested in cars since a young age. I liked older cars and how they looked compared to new one. I saw a movie involving Nascar. After this I looked into different kinds of racing and this is the one I found most interesting. My dad has taken me to streets that aren’t used a lot and let me drive his car His car is older and has the same gears as you would use in drag racing. Drag racing test the speed and performance of cars and the skills of daring

Paris is Burning 1. I would argue that the group of poor gay minorities‚ like the people in the ball‚ is a subculture in itself. This group is a subculture of the gay culture. The distinguishing aspects of the group are that they are poor‚ gay‚ and minorities. Another distinguishing aspect is that members of this subculture are typically outcasts. They have been rejected by family members‚ friends‚ and American society as a whole. “It’s hard to imagine a more outcast group in American society
