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.
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.

There are two causes of aerodynamic force: [1]: §4.10 [2] [3]: 29 the normal force due to the pressure on the surface of the body; the shear force due to the viscosity of the gas, also known as skin friction. Pressure acts normal to the surface, and shear force acts parallel to the surface. Both forces act locally.
The second term in the above equation, plays the role of a gravitational force. If f f α {\displaystyle f_{f}^{\alpha }} is the correct expression for force in a freely falling frame ξ α {\displaystyle \xi ^{\alpha }} , we can use then the equivalence principle to write the four-force in an arbitrary coordinate x μ {\displaystyle x^{\mu }} :
Books are listed in alphabetical order by title, ignoring the leading articles "A", "An" and "The". Novel series are alphabetical by author-designated name or, if there is none, the title of the first novel in the series or some other reasonable designation.
The name comes from quinta essentia (fifth element). So called in Latin starting from the Middle Ages, this was the (first) element added by Aristotle to the other four ancient classical elements because he thought it was the essence of the celestial world. Aristotle posited it to be a pure, fine, and primigenial element.
