GRAVITATION Kepler’s Laws Towards the end of the sixteenth century‚ Tycho Brahe collected a huge amount of data giving precise measurements of the position of planets. Johannes Kepler‚ after a detailed analysis of the measurements announced three laws in 1619. 1. The orbit of each planet is an ellipse which has the Sun at one of its foci. 2. Each planet moves in such a way that the (imaginary) line joining it to the Sun sweeps out equal areas in equal times. 3. The squares of the periods

Physics began when man first started to study his surroundings. Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the period of Greek culture that the first systematic treatment of physics started with the use of mechanics. Thales is often said to have been the first scientist‚ and the first Greek philosopher

The type of physics that I will be presenting is a branch of Fluid Mechanics. Fluid mechanics studies the physics of gases and liquids. Hydraulics is defined as: "a branch of science that deals with practical applications of liquid in motion." Merriam-Webster’s Medical Dictionary‚ via www.dictionary.com The science started over thousands of years ago with Aristotle (384-322 B.C.) and Archimedes (287-212 B.C.). Many European scientists also contributed to hydraulics‚ including

I. Introduction Physics is the natural science that involves the study of matter and its motion through space and time‚ along with related concepts such as energy and force. More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy. Over the last two millennia‚ physics was a part of natural philosophy along with chemistry‚ certain branches

You throw the ball. You catch the ball‚" said a well-respected baseball manager by the name of Casey Stengel. Mr. Stengel was a baseball man‚ not a mathematician nor a physicist. Physics and mathematics can be applied to the game of baseball on every pitch‚ and on every swing of the bat. To understand the physics of the game‚ it is first necessary to look at the center of the game‚ the ball. Section 1.09 of the Official Baseball Rules states that the ball must weigh between 5 ounces and 5 ¼

The Physics of Baseball The sport of baseball has been around for over two hundred years‚ roughly since the 1800s. Invented by a man named Alexander Cartwright. It is known as “Americas past time.” Baseball is the national sport of the USA. The first baseball game played was in New York on June 19‚ 1845. And is played by thousands of people throughout the years. Much like any sport‚ it has changed with time. The first rulebook of baseball was issued in 1877. And it has been changing every year
