THRUST • The force acting on a body perpendicular to its surface is called thrust. • Thrust is the total force acting on the surface of the body. • Thrust per unit area is pressure Pressure = Thrust Area S.I unit of pressure is N/m2 or Pascal EVERYDAY OBSERVATIONS RELATED TO PRESSURE: • School bags have wide straps so that the weight of the bag falls over a large area of the shoulder producing less pressure on the shoulder. Due to this less pressure

Although the world may disagree about many issues there is a commonality that continuously unites nations from all over the world‚ and it is a fundamental system in which the world cannot function without‚ the International System of Units (SI). The SI was established in 1960 by the 11th Conference of Weight and Measures; it began with 17 nations including the United States and today has become widely used among 51 nations (Historical). The SI is a metric system of units of measurement and is predominantly

Ankit Shingala Dr. Campagnolo Chemistry H September 24‚ 2013 Lab on Density of Four Metals Conclusion In this lab we studied the densities of four different metals using a caliper‚ a digital scale‚ and a calculator. Three metals were pure elements like copper‚ iron‚ and aluminum. The fourth metal was an alloy which was brass. The purposes of this lab were to demonstrate that different metal elements have different densities‚ and that alloys have densities somewhere between those elements that

groups are very long. One is called "The history of formal deduction" and it goes all the way back to Aristotle and Euclid and other people who lived at that time. The other is "the history of mathematical analysis" which goes back to the times of Archimedes‚ who was in the same era as Aristotle and Euclid. These to groups or streams were separate for a long time until Newton invented Calculus‚ which brought Math and logic together. Somebody who studies mathematical logic and gives his or her own

way other great thinkers viewed geometry and influenced the other developments in mathematics. Another mathematical development that came from ancient Greece is Pythagoras’ theorem. This theorem is still important to all math and science classes. Archimedes discovered things in many different subject but he invented integral calculus and gave us the calculated vale of pi (Nagle

There are many ancient civilizations that are worthy enough to be considered exceptional‚ however‚ Ancient Greece‚ without a doubt‚ is one of the most impressive ancient civilizations. What makes Ancient Greece so impressive is it’s abundant number of achievements; such as founding democracy‚ developing the world’s first libraries‚ creating the Olympic Games‚ achieving beautiful architectural feats and spitting out mathematical and scientific discoveries like no other civilization before‚ just to

“Father of Modern Science”. One of his most famous inventions is the hydrostatic balance. Using this device‚ he could accurately weigh objects both in water and the air. Galileo got the idea from the "Eureka" story about Archimedes and the King of Syracuse’s crown in which Archimedes had to prove if the king’s crown was made of real gold or not. By submerging an item in the water of the device‚ he was able to precisely measure its volume by determining the volume of water displaced. Another invention
