The Wright brothers, Wilbur and Orville, are often depicted as lone geniuses, secretly assembling the first successful powered aircraft far from civilization at Kitty Hawk on the Outer Banks of North Carolina. There is a germ of truth in the popular story, but only a germ. The brothers succeeded while so many other experimenters failed not because…

Paul Hewitt's "Figuring Physics" in the Feb. 2016 issue asked whether it would take a larger velocity change to stop a satellite in a circular orbit or to cause it to escape. An extension of this problem asks: What "minimum" velocity change is required to crash a satellite into the planet, and how does that compare with the…

"How does an aircraft fly?" is one of the most frequently asked science questions by young pupils. The lift on airplane wings also makes a great example of the application of the Bernoulli principle while teaching fluid mechanics in introductory physics and engineering courses. The topic is of great interest and is therefore covered in…

Educators are constantly trying to find new ways of motivating their students. In subjects such as mechanics with a strong mathematical component, it is particularly important to devise real-life examples that can increase interest and student excitement. Aircraft flight is a topic that most young people find exciting. It therefore would seem…

"The 2006 Winter Meeting of the AAPT Was Over..."and the flight home from Anchorage to Cleveland was just about to end--eight hours in the air, only two complimentary beverages, no meals, a jump across four time zones, a one-year-old baby daughter, and a wife whose motto for the week was, "Why did they choose to have a winter meeting in Alaska?"…

This paper describes our flight aboard NASA's C9 "Weightless Wonder," an aircraft that creates multiple periods of microgravity by conducting a series of parabolic maneuvers over the Gulf of Mexico. Because passengers often develop motion sickness during these parabolic maneuvers, the C9 is more affectionately known as the "Vomit Comet." To…

Presents a problem involving the double-slit interference pattern that relates to the real-world situation of guiding an aircraft to a safe landing. (JRH)

Recounts the contributions of Robert Goddard from the years of 1911 to 1930 to the development of the physics of rocketry. Discusses the results of Goddard's series of rocket experiments endorsed by the Smithsonian Institute, and Goddard's claims to priority in the development of rocket theory. (MDH)

Discussed is the use of model rocketry to teach the principles of Newtonian mechanics. Included are forces involved; calculations for vertical launches; two-dimensional trajectories; and variations in mass, drag, and launch angle. (CW)
