(CBS MoneyWatch) For more than a decade, college tuition has been rising far beyond the rate of inflation at public colleges and universities. According to College Board figures, tuition and fees increased 5.4 percent annually above inflation in the decade since the 2001-2002 school year. Ouch.. Real net average tuition at state universities, which is the price after grants are deducted, rose 33.1 percent ($3,415 to $4,546). In comparison, average net tuition at private institutions has risen 21.2 percent during the same period.
Newton's Universal Law of Gravitation. Newton's Universal Law of Gravitation: 'a simple equation, but devastatingly effective'. Newton's equation first appeared in the PhilosophiÃ¦ Naturalis Principia Mathematica, July 1687. It describes why that apple fell from that tree in that orchard in Lincolnshire.
The force is proportional to the product of the two masses and inversely proportional to the square of the distance between them. The first test of Newton's theory of gravitation between masses in the laboratory was the Cavendish experiment conducted by the British scientist Henry Cavendish in 1798. It took place 111 years after the publication of Newton's Principia and 71 years after his death. Newton's law of gravitation resembles Coulomb's law of electrical forces, which is used to calculate the magnitude of electrical force arising between two charged bodies. Both are inverse-square laws, where force is inversely proportional to the square of the distance between the bodies.
