  2. Newton's laws of motion - Wikipedia

    en.wikipedia.org/wiki/Newton's_laws_of_motion

    Newton's second law is sometimes presented as a definition of force, i.e., a force is that which exists when an inertial observer sees a body accelerating. In order for this to be more than a tautology — acceleration implies force, force implies acceleration — some other statement about force must also be made.

  3. Law of attraction - Wikipedia

    en.wikipedia.org/wiki/Law_of_attraction

    Law of attraction may refer to: Electromagnetic attraction; Newton's law of universal gravitation; Law of attraction (New Thought), a New Thought belief;

  4. Proximity principle - Wikipedia

    en.wikipedia.org/wiki/Proximity_principle

    These are not in any specific order, but they are important to consider to fully understand the principles of attraction. The other principles are the elaboration principle , the similarity principle, the complementarity principle, the reciprocity principle, and the minimax principle.

  5. Newton's law of universal gravitation - Wikipedia

    The publication of the law has become known as the "first great unification", as it marked the unification of the previously described phenomena of gravity on Earth with known astronomical behaviors. [1] [2] [3] This is a general physical law derived from empirical observations by what Isaac Newton called inductive reasoning. [4]

  6. Law of attraction (New Thought) - Wikipedia

    en.wikipedia.org/wiki/Law_of_attraction_(New...

    The law of attraction is the New Thought spiritual belief that positive or negative thoughts bring positive or negative experiences into a person's life. [1] [2] The belief is based on the idea that people and their thoughts are made from "pure energy" and that like energy can attract like energy, thereby allowing people to improve their health, wealth, or personal relationships.

    (This reappears in Definition 5 of the Principia.) 2: 'Inherent force' of a body is defined in a way that prepares for the idea of inertia and of Newton's first law (in the absence of external force, a body continues in its state of motion either at rest or in uniform motion along a straight line). (Definition 3 of the Principia is to similar ...

  8. Force between magnets - Wikipedia

    en.wikipedia.org/wiki/Force_between_magnets

    Magnets exert forces and torques on each other through the interaction of their magnetic fields.The forces of attraction and repulsion are a result of these interactions. The magnetic field of each magnet is due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of fundamental particles (such as electrons) that make up the mater

  9. Reaction (physics) - Wikipedia

    en.wikipedia.org/wiki/Reaction_(physics)

    A possible cause of this problem is that the third law is often stated in an abbreviated form: For every action there is an equal and opposite reaction, [8] without the details, namely that these forces act on two different objects. Moreover, there is a causal connection between the weight of something and the normal force: if an object had no ...
