  3. List of equations in gravitation - Wikipedia

    en.wikipedia.org/wiki/List_of_equations_in...

    A common misconception occurs between centre of mass and centre of gravity.They are defined in similar ways but are not exactly the same quantity. Centre of mass is the mathematical description of placing all the mass in the region considered to one position, centre of gravity is a real physical quantity, the point of a body where the gravitational force acts.

  4. Introduction to general relativity - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_general...

    General relativity is a theory of gravitation developed by Albert Einstein between 1907 and 1915. The theory of general relativity says that the observed gravitational effect between masses results from their warping of spacetime.

  5. Newton's law of universal gravitation - Wikipedia

    en.wikipedia.org/wiki/Newton's_law_of_universal...

    The first test of Newton's law of gravitation between masses in the laboratory was the Cavendish experiment conducted by the British scientist Henry Cavendish in 1798. [5] It took place 111 years after the publication of Newton's Principia and approximately 71 years after his death.

  6. Equivalence principle - Wikipedia

    en.wikipedia.org/wiki/Equivalence_principle

    The equivalence principle is the hypothesis that the observed equivalence of gravitational and inertial mass is a consequence of nature. The weak form, known for centuries, relates to masses of any composition in free fall taking the same trajectories and landing at identical times.

    The cover of the first volume of Gravitation as published by Gentosha in March 1996 in Japan. The chapters of Gravitation are written and illustrated by Maki Murakami. Tokyopop licensed the series for an English-language release in North America and published the twelve volumes from August 5, 2003, to July 12, 2005.

  8. Gravitational acceleration - Wikipedia

    en.wikipedia.org/wiki/Gravitational_acceleration

    At a fixed point on the surface, the magnitude of Earth's gravity results from combined effect of gravitation and the centrifugal force from Earth's rotation. [2] [3] At different points on Earth's surface, the free fall acceleration ranges from 9.764 to 9.834 m/s 2 (32.03 to 32.26 ft/s 2), [4] depending on altitude, latitude, and longitude.

  9. Apparent weight - Wikipedia

    en.wikipedia.org/wiki/Apparent_weight

    In physics, apparent weight is a property of objects that corresponds to how heavy an object appears to be. The apparent weight of an object will differ from the ordinary weight of an object whenever the force of gravity acting on the object is not balanced by an equal but opposite contact force.
