  2. Newton's laws of motion - Wikipedia

    en.wikipedia.org/wiki/Newton's_laws_of_motion

    Newton's laws are often stated in terms of point or particle masses, that is, bodies whose volume is negligible. This is a reasonable approximation for real bodies when the motion of internal parts can be neglected, and when the separation between bodies is much larger than the size of each.

  3. Newton's law of universal gravitation - Wikipedia

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

    Before Newton’s law of gravity, there were many theories explaining gravity. Philoshophers made observations about things falling down − and developed theories why they do – as early as Aristotle who thought that rocks fall to the ground because seeking the ground was an essential part of their nature.

  4. Scientific law - Wikipedia

    en.wikipedia.org/wiki/Scientific_law

    The term "scientific law" is traditionally associated with the natural sciences, though the social sciences also contain laws. [11] For example, Zipf's law is a law in the social sciences which is based on mathematical statistics. In these cases, laws may describe general trends or expected behaviors rather than being absolutes.

  5. List of eponymous laws - Wikipedia

    en.wikipedia.org/wiki/List_of_eponymous_laws

    Euler's laws of motion: extends Newton's laws of motion for point particle to rigid body motion. Faraday's law of induction: a magnetic field changing in time creates a proportional electromotive force. Named for Michael Faraday, based on his work in 1831.

  6. Classical mechanics - Wikipedia

    en.wikipedia.org/wiki/Classical_mechanics

    In mechanics, Newton was also the first to provide the first correct scientific and mathematical formulation of gravity in Newton's law of universal gravitation. The combination of Newton's laws of motion and gravitation provides the fullest and most accurate description of classical mechanics.

  7. Philosophiæ Naturalis Principia Mathematica - Wikipedia

    en.wikipedia.org/wiki/Philosophiæ_Naturalis...

    Newton's tract De motu corporum in gyrum, which he sent to Halley in late 1684, derived what is now known as the three laws of Kepler, assuming an inverse square law of force, and generalised the result to conic sections. It also extended the methodology by adding the solution of a problem on the motion of a body through a resisting medium.

  8. Inertia - Wikipedia

    en.wikipedia.org/wiki/Inertia

    Inertia is the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes the velocity to change. It is one of the fundamental principles in classical physics, and described by Isaac Newton in his first law of motion (also known as The Principle of Inertia). [1]

  9. Non-inertial reference frame - Wikipedia

    en.wikipedia.org/wiki/Non-inertial_reference_frame

    In classical mechanics it is often possible to explain the motion of bodies in non-inertial reference frames by introducing additional fictitious forces (also called inertial forces, pseudo-forces, [5] and d'Alembert forces) to Newton's second law. Common examples of this include the Coriolis force and the centrifugal force.
