  2. Salvatore Pais - Wikipedia

    A "craft using an inertial mass reduction device" (2016), one embodiment of which could be a high speed "hybrid aerospace/undersea craft" able to "engineer the fabric of our reality at the most fundamental level", [7] the patent application for which was supported by the Naval Aviation Enterprise's chief technical officer on the grounds that ...

  3. Reduced mass - Wikipedia

    en.wikipedia.org/wiki/Reduced_mass

    In physics, reduced mass is a measure of the effective inertial mass of a system with two or more particles when the particles are interacting with each other. Reduced mass allows the two-body problem to be solved as if it were a one-body problem. Note, however, that the mass determining the gravitational force is not reduced.

  4. Inertia damper - Wikipedia

    en.wikipedia.org/wiki/Inertia_damper

    Inertial compensators are also used in simulators or rides, making them more realistic by creating artificial sensations of acceleration and other movement. The Disneyland ride “Star Tours: The Adventure Continues” is a fair example of this principle. There are many types of physical devices that can act as inertia dampers:

  5. Einstein's thought experiments - Wikipedia

    en.wikipedia.org/wiki/Einstein's_thought_experiments

    Objects also have "inertial mass," which determines the relationship between the force applied to an object and how much it accelerates. Newton had pointed out that, even though they are defined differently, gravitational mass and inertial mass always seem to be equal. But until Einstein, no one had conceived a good explanation as to why this ...

  6. Rotation around a fixed axis - Wikipedia

    en.wikipedia.org/wiki/Rotation_around_a_fixed_axis

    Rotation around a fixed axis or axial rotation is a special case of rotational motion around an axis of rotation fixed, stationary, or static in three-dimensional space.This type of motion excludes the possibility of the instantaneous axis of rotation changing its orientation and cannot describe such phenomena as wobbling or precession.

  7. Human-powered transport - Wikipedia

    en.wikipedia.org/wiki/Human-powered_transport

    Human-powered transport is the transport of person(s) and/or goods using human muscle power.Unlike animal-powered transport, human-powered transport has existed since time immemorial in the form of walking, running and swimming, as well as small vehicles such as litters, rickshaws, wheelchairs and wheelbarrows.

  8. Tamper (nuclear weapon) - Wikipedia

    en.wikipedia.org/wiki/Tamper_(nuclear_weapon)

    The use of enriched uranium tampers therefore became more common once enriched uranium became more plentiful. An important development after World War II was the lightweight beryllium tamper. In a boosted device the thermonuclear reactions greatly increase the production of neutrons, which makes the inertial property of tampers less important.

  9. Isoinertial - Wikipedia

    en.wikipedia.org/wiki/Isoinertial

    The isoinertial's muscle activity follows the muscular action of the sporting gesture or rather what the body or parts of it are in duty to perform in sports, according to which, in strength and speed variable, an inertial load (such as a ball), a limb or the body itself (such as when accelerating or changing direction) the athlete is forced to respond at the level coordinative motor and ...
