  2. gc (engineering) - Wikipedia

    en.wikipedia.org/wiki/Gc_(engineering)

    In engineering and physics, g c is a unit conversion factor used to convert mass to force or vice versa. [1] It is defined as = In unit systems where force is a derived unit, like in SI units, g c is equal to 1.

  3. List of equations in classical mechanics - Wikipedia

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

    Classical mechanics is the branch of physics used to describe the motion of macroscopic objects. [1] It is the most familiar of the theories of physics. The concepts it covers, such as mass, acceleration, and force, are commonly used and known. [2] The subject is based upon a three-dimensional Euclidean space with fixed axes, called a frame of ...

  4. Tsiolkovsky rocket equation - Wikipedia

    en.wikipedia.org/wiki/Tsiolkovsky_rocket_equation

    A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...

  5. Specific force - Wikipedia

    en.wikipedia.org/wiki/Specific_force

    It can also be called mass-specific weight (weight per unit mass), as the weight of an object is equal to the magnitude of the gravity force acting on it. The g-force is an instance of specific force measured in units of the standard gravity ( g ) instead of m/s², i.e., in multiples of g (e.g., "3 g ").

  6. Thrust - Wikipedia

    en.wikipedia.org/wiki/Thrust

    Pound (force) – Earth's gravitational pull on a one-pound mass "Pound of thrust": thrust (force) required to accelerate one pound at one g; Stream thrust averaging – Process to convert 3D flow into 1D; Thrust-to-weight ratio – Dimensionless ratio of thrust to weight of a jet or propeller engine

  7. Equations for a falling body - Wikipedia

    en.wikipedia.org/wiki/Equations_for_a_falling_body

    A set of equations describing the trajectories of objects subject to a constant gravitational force under normal Earth-bound conditions.Assuming constant acceleration g due to Earth's gravity, Newton's law of universal gravitation simplifies to F = mg, where F is the force exerted on a mass m by the Earth's gravitational field of strength g.

  8. Physical quantity - Wikipedia

    en.wikipedia.org/wiki/Physical_quantity

    Ampèremetre (Ammeter) A physical quantity (or simply quantity) [1] [a] is a property of a material or system that can be quantified by measurement.A physical quantity can be expressed as a value, which is the algebraic multiplication of a numerical value and a unit of measurement.

  9. Pound (mass) - Wikipedia

    en.wikipedia.org/wiki/Pound_(mass)

    The equivalence for the pound was given as 1 lb = 453.592 65 g or 0.45359 kg, which made the kilogram equivalent to about 2.204 6213 lb. In 1883, it was determined jointly by the standards department of the British Board of Trade and the Bureau International that 0.453 592 4277 kg was a better approximation, and this figure, rounded to 0.453 ...
