  2. Momentum - Wikipedia

    en.wikipedia.org/wiki/Momentum

    In Newtonian mechanics, momentum (pl.: momenta or momentums; more specifically linear momentum or translational momentum) is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction.

  3. Momentum investing - Wikipedia

    en.wikipedia.org/wiki/Momentum_investing

    Momentum investing is a system of buying stocks or other securities that have had high returns over the past three-to-twelve months, and selling those that have had ...

  4. Angular momentum - Wikipedia

    en.wikipedia.org/wiki/Angular_momentum

    The angular momentum of m is proportional to the perpendicular component v ⊥ of the velocity, or equivalently, to the perpendicular distance r ⊥ from the origin. Angular momentum is a vector quantity (more precisely, a pseudovector) that represents the product of a body's rotational inertia and rotational velocity (in radians/sec) about a ...

  5. Impulse (physics) - Wikipedia

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

    Momentum is a vector quantity, so impulse is also a vector quantity: =. [1] Newton’s second law of motion states that the rate of change of momentum of an object is equal to the resultant force F acting on the object: =,

  6. Landé g-factor - Wikipedia

    en.wikipedia.org/wiki/Landé_g-factor

    Here, J is the total electronic angular momentum, L is the orbital angular momentum, and S is the spin angular momentum. Because = / for electrons, one often sees this formula written with 3/4 in place of (+). The quantities g L and g S are other g-factors of an electron.

  7. Uncertainty principle - Wikipedia

    en.wikipedia.org/wiki/Uncertainty_principle

    While position and momentum are associated with a single particle, time is a system property: it has no operator needed for the Robertson–Schrödinger relation. [1] The mathematical treatment of stable and unstable quantum systems differ. [45] These factors combine to make energy–time uncertainty principles controversial.

  8. Lift (force) - Wikipedia

    en.wikipedia.org/wiki/Lift_(force)

    The momentum theorem states that the integrated force exerted at the boundaries of the control volume (a surface integral), is equal to the integrated time rate of change (material derivative) of the momentum of fluid parcels passing through the interior of the control volume. For a steady flow, this can be expressed in the form of the net ...

  9. Momentum (finance) - Wikipedia

    en.wikipedia.org/wiki/Momentum_(finance)

    In finance, momentum is the empirically observed tendency for rising asset prices or securities return to rise further, and falling prices to keep falling. For instance, it was shown that stocks with strong past performance continue to outperform stocks with poor past performance in the next period with an average excess return of about 1% per month.
