  2. Fundamental interaction - Wikipedia

    en.wikipedia.org/wiki/Fundamental_interaction

    The gravitational and electromagnetic interactions produce long-range forces whose effects can be seen directly in everyday life. The strong and weak interactions produce forces at subatomic scales and govern nuclear interactions inside atoms. Some scientists hypothesize that a fifth force might exist, but these hypotheses remain speculative.

  3. Fifth force - Wikipedia

    en.wikipedia.org/wiki/Fifth_force

    The above experiments search for a fifth force that is, like gravity, independent of the composition of an object, so all objects experience the force in proportion to their masses. Forces that depend on the composition of an object can be very sensitively tested by torsion balance experiments of a type invented by Loránd Eötvös.

  4. George Cayley - Wikipedia

    en.wikipedia.org/wiki/George_Cayley

    [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 ...

  5. Life on the Genesee: Rochester students set sail, study science

    Fifth-grader students from the Rochester City School District took a boat ride on the Genesee River to learn about life in and out of the water as part of their 5th-grade science curriculum.

  6. Spacecraft flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Spacecraft_flight_dynamics

    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 ...
