A superconductor is a metallic alloy that conducts electricity without resistance‚ below a certain temperature. Once in motion‚ an electrical current will flow in a closed loop within a superconducting material. This is the closest to scientists of a perpetual motion machine. In 1911‚ Heike Kamerlingh Onnes first observed superconductivity. He used mercury and cooled to four degrees Kelvin. When the mercury reached that temperature‚ the resistance disappeared. That meant that the electrical current

Flight is a phenomenon that has long been a part of the natural world. Birds fly not only by flapping their wings‚ but by gliding with their wings outstretched for long distances. Smoke‚ which is composed of tiny particles‚ can rise thousands of feet into the air. Both these types of flight are possible because of the principles of physical science. Likewise‚ man-made aircraft rely on these principles to overcome the force of gravity and achieve flight. Lighter-than-air craft‚ such as the hot

intertwined around itself‚ but regardless of how big‚ fast‚ or gravity defying they are‚ they all use the same natural force – gravity. The more twisting‚ turning‚ flipping‚ and the faster a roller coaster goes‚ the more the coaster depends on the law of physics‚ not mechanics‚ to keep it moving. There is no onboard motor on roller coasters but they can still reach speeds that exceed the limits of a car on the parkway‚ while completing a curve‚ twist‚ rise‚ or plunge.

ours‚ our findings can hardly pale into insignificance as errors and the cause of uncertainty are discussed and ways to improve the experiment are suggested‚ which can possibly spur further studies on this realm of knowledge. I. Introduction In physics‚ there are mainly two ways from which useful equations can be derived. One from them is to make good use of the mathematical expression of the theories formulated by our predecessors. An archetype to this notion is the Newton’s second law‚ which states
