  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. 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 ]

  4. Motion - Wikipedia

    en.wikipedia.org/wiki/Motion

    Newton's three laws are: A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force. (This is known as the law of inertia.) Force is equal to the change in momentum per change in time ().

  5. Inertial frame of reference - Wikipedia

    en.wikipedia.org/wiki/Inertial_frame_of_reference

    The laws of nature take a simpler form in inertial frames of reference because in these frames one did not have to introduce inertial forces when writing down Newton's law of motion. [ 42 ] In practice, using a frame of reference based upon the fixed stars as though it were an inertial frame of reference introduces little discrepancy.

  6. Laws of motion - Wikipedia

    en.wikipedia.org/wiki/Laws_of_motion

    In physics, a number of noted theories of the motion of objects have developed. Among the best known are: Classical mechanics. Newton's laws of motion; Euler's laws of motion; Cauchy's equations of motion; Kepler's laws of planetary motion ; General relativity; Special relativity; Quantum mechanics

  7. Three laws - Wikipedia

    en.wikipedia.org/wiki/Three_laws

    Newton's laws of motion, three physical laws that, together, laid the foundation for classical mechanics The laws of thermodynamics , originally three physical laws describing thermodynamic systems, though a fourth one was later formulated and is now counted as the zeroth law of thermodynamics

  9. History of classical mechanics - Wikipedia

    en.wikipedia.org/wiki/History_of_classical_mechanics

    Aristotle saw a distinction between "natural motion" and "forced motion", and he believed that 'in a void' i.e.vacuum, a body at rest will remain at rest [3] and a body in motion will continue to have the same motion. [4] In this way, Aristotle was the first to approach something similar to the law of inertia.
