Edgar Xiong David Blackburn Period 3 Physics of Flight One may wonder‚ what is flight? Many just stare up into the blue skies above and assume. while others devote their lives to discovering and finding a passion in aviation. Flight can be simply characterized as the [powered] gliding of an object through the air‚ but the wonders of soaring through the air does not simply stop there‚ instead‚ flight is a whole myriad of forces acting on each other‚ as so found out by scientists decades

Statistics Investigation Introduction A new drug was developed that was claimed to lower the cholesterol level in humans. A leading heart specialist was interested to know if the claim made by the company selling the drug was accurate. They enlisted the help of 50 patients. They agreed to take part in an experiment in which 25 patients would be randomly allocated to a group that would take the new drug and the other 25 would take an identical looking pill that was a placebo (a sugar pill that

AS Level Physics: Terms & Definitions:- Measurement Random errors are errors of measurements that result in a scatter of readings about a mean value. Systematic errors are errors of measurement which occur according to some fixed patterns such that they consistently give out an over-estimation or under-estimation of the true value. Accuracy is a measure of how close the results of an experiment agree with the true value. Precision is a measure of how close the results of an experiment

The Physics of Rainbows As we are coming down to the final weeks of winter‚ the days are getting longer‚ and it is slowing starting to warm up. We are all looking forward to springtime‚ with its promises of flowers and rain. Along with this rain brings reminders of rainbows. As Donald Ahrens says in the Meteorology Today magazine‚ “rainbows are one of the most spectacular light shows observed on earth (About).” In fact‚ one of the best ways to view a rainbow at it’s utmost
