    angular momentum. Also (rarely) moment of momentum or rotational momentum. The rotational equivalent of linear momentum. It is an important quantity in physics because it is a conserved quantity–that is, the total angular momentum of a closed system remains constant. angular velocity (ω)

  3. Momentum - Wikipedia

    en.wikipedia.org/wiki/Momentum

    The quantity V = qA is sometimes called the potential momentum. [41] [42] [43] It is the momentum due to the interaction of the particle with the electromagnetic fields. The name is an analogy with the potential energy U = qφ, which is the energy due to the

  4. 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: =,

  5. Population momentum - Wikipedia

    en.wikipedia.org/wiki/Population_momentum

    Population momentum has implications for population policy for a number of reasons. 1. With respect to high-fertility countries (for example in the developing world), a positive population momentum, meaning that the population is increasing, states that these countries will continue to grow despite large and rapid declines in fertility. 2.

    From Lucretius' De rerum natura book VI, where it refers in context to the motion of a thunderbolt across the sky, which acquires power and momentum as it goes. This metaphor was adapted as the state motto of New Mexico (adopted in 1887 as the territory's motto, and kept in 1912 when New Mexico received statehood) and is seen on the seal .

  7. Position and momentum spaces - Wikipedia

    en.wikipedia.org/wiki/Position_and_momentum_spaces

    Mathematically, the duality between position and momentum is an example of Pontryagin duality. In particular, if a function is given in position space, f(r), then its Fourier transform obtains the function in momentum space, φ(p). Conversely, the inverse Fourier transform of a momentum space function is a position space function.

  8. Force - Wikipedia

    en.wikipedia.org/wiki/Force

    Torque is the rotation equivalent of force in the same way that angle is the rotational equivalent for position, angular velocity for velocity, and angular momentum for momentum. As a consequence of Newton's first law of motion, there exists rotational inertia that ensures that all bodies maintain their angular momentum unless acted upon by an ...

  9. Linear motion - Wikipedia

    en.wikipedia.org/wiki/Linear_motion

    The motion in which all the particles of a body move through the same distance in the same time is called translatory motion. There are two types of translatory motions: rectilinear motion; curvilinear motion.
