PPT-Archimedes

287 BC 212 BC Archimedes of Syracuse was a Greek mathematician physicist engineer inventor and astronomer Although few details of his life are known he is regarded as one of the leading scientists in classical antiquity Among his advances in physics are the foundations of hydrostatics statics and an explanation of the principle of the lever He is credited with designing innovative machines including siege engines and the screw pump that bears his name Modern experiments have tested claims that Archimedes designed machines capable of lifting attacking ships out of the water and setting ships on fire using an array of mirrors. Principles Density The density pronounced rho of an object is the ratio of its mass to its volume Since very few substances have exactly the same density this property can be used to identify an element or compound Buoyant Force When you are swim (1.2))]=v1+12at. 1 Buoyancy and Archimedes Old Guys and their formulas.
