Spacecraft flight dynamics is the application of mechanical dynamics to model how the external forces acting on a space vehicle or spacecraft determine its flight path. These forces are primarily of three types: propulsive force provided by the vehicle's engines; gravitational force exerted by the Earth and other celestial bodies; and ...
[4] [5] He was a pioneer of aeronautical engineering and is sometimes referred to as "the father of aviation." [3] He identified the four forces which act on a heavier-than-air flying vehicle: weight, lift, drag and thrust. [6] Modern aeroplane design is based on those discoveries and on the importance of cambered wings, also proposed by Cayley ...
The erector at Pad 19 is lowered in preparation for the launch of Gemini 5. The launch went perfectly except for a few seconds of pogo oscillation (axial vibration of the rocket). This was measured at +0.38 g (3.7 m/s 2) during first stage flight, exceeding the permitted +0.25 g (2.5 m/s 2) for a total of about 13 seconds. Conrad and Cooper ...
[5] [6] Thus Newton's theory violated the tradition, going back to Descartes, that there should be no action at a distance. [7] Conversely, during the 1820s, when explaining magnetism, Michael Faraday inferred a field filling space and transmitting that force. Faraday conjectured that ultimately, all forces unified into one. [8]
An educational program entitled You Can Soar [12] allowed participating 5th through 8th grade students to hone their mathematical skills as they also learned about time zones, aerodynamics, weather gauging, and geography. Addressing the countries that Finch visited, the program's cultural studies portion taught poetry, language, and art.

A static equilibrium between two forces is the most usual way of measuring forces, using simple devices such as weighing scales and spring balances. For example, an object suspended on a vertical spring scale experiences the force of gravity acting on the object balanced by a force applied by the "spring reaction force", which equals the object ...
The Douglas D-558-2 Skyrocket (or D-558-II) is a rocket and jet-powered research supersonic aircraft built by the Douglas Aircraft Company for the United States Navy.On 20 November 1953, shortly before the (17 December) 50th anniversary of powered flight, Scott Crossfield piloted the Skyrocket to Mach 2, or more than 1,290 mph (2076 km/h), the first time an aircraft had exceeded twice the ...
