Module 2 Honors Extension: The Physics in Swimming Physics is defined as the branch of science concerning the study of matter and energy and the interactions between the two. Physics tries to explain the nature of the world around us‚ how things happen and why. Swimming displays some physical properties‚ such as buoyancy‚ drag resistance and propulsion. We swimmers are at a constant battle to stay afloat‚ while fighting through the water and propelling ourselves forward‚ and we do so using technique

The Importance of Physics to Society Physics - the study of matter‚ energy and their interactions - is an international enterprise‚ which plays a key role in the future progress of humankind. The support of physics education and research in all countries is important because: 1. Physics is an exciting intellectual adventure that inspires young people and expands the frontiers of our knowledge about Nature. 2. Physics generates fundamental knowledge needed for the future technological advances

I absolutely love jumping on the trampoline but I never really thought there was any physics involved. I knew you had to use a force to jump up and gravity pulls you back down obviously. An American inventor named George Nissen first invented the trampoline in 1935. (Silvia) A trampoline is defined as an elastic disc of hard canvas held up by metal springs attached to a metal skeletal frame. Kinetic and Potential energy allow you to be able to jump on a trampoline. PE=mgh this equation helps you

Applications of Physics in Everyday Life By Steve Johnson‚ eHow Contributor Even walking manipulates physics‚ allowing people to proceed in a state of "constant falling." Physics extends well into people’s everyday lives -- imprisoning people within its forces. From each step a person takes to the evolution of the body‚ physics has several long-term as well as short-term effects and uses. For everyday living‚ many technologies have even exploited the rules of physics. 1. Simple Mechanical

The new model of movement‚ represented by roller shoes‚ has influenced upon the majority of youngsters.The charm of roller shoes seduces children and knocks them out‚ which also shows unfettered spirit.However‚ every coin has two sides. As the popularity of roller skating‚ opposed voices occur. There is no denying that roller shoes wrought fundamental changes in our life. Nothing is more critical than to do physical exercises. The more exercises we do‚ the more healthy we are. But what people consider

Roller skating is one of favorite sports for children and we often see them playing roller skating in the square. Roller skating is derived from skating. Data records‚ roller skating invented by the Dutch in eighteenth Century. Through continuous improvement and innovation‚ until the early 1980s‚ this is roughly the Roller skating that people see in the market today. In 1992‚ International Olympic Committee decided to include roller skating as an official event in the Olympic Games. Rollers skating
