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. Moment (physics) - Wikipedia

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

   The moment of force, or torque, is a first moment: =, or, more generally, .; Similarly, angular momentum is the 1st moment of momentum: =.Momentum itself is not a moment.; The electric dipole moment is also a 1st moment: = for two opposite point charges or () for a distributed charge with charge density ().

4. Newton's laws of motion - Wikipedia

   en.wikipedia.org/wiki/Newton's_laws_of_motion

   When Newton's laws are applied to rotating extended bodies, they lead to new quantities that are analogous to those invoked in the original laws. The analogue of mass is the moment of inertia, the counterpart of momentum is angular momentum, and the counterpart of force is torque. Angular momentum is calculated with respect to a reference point ...

5. Equations of motion - Wikipedia

   en.wikipedia.org/wiki/Equations_of_motion

   There are two main descriptions of motion: dynamics and kinematics.Dynamics is general, since the momenta, forces and energy of the particles are taken into account. In this instance, sometimes the term dynamics refers to the differential equations that the system satisfies (e.g., Newton's second law or Euler–Lagrange equations), and sometimes to the solutions to those equations.

6. Impulse (physics) - Wikipedia

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

   In classical mechanics, impulse (symbolized by J or Imp) is the change in momentum of an object. If the initial momentum of an object is p 1, and a subsequent momentum is p 2, the object has received an impulse J: =. Momentum is a vector quantity, so impulse is also a vector quantity.

7. Momentum mapping format - Wikipedia

   en.wikipedia.org/wiki/Momentum_mapping_format

   The evolution of momentum on the grid under each scheme is identical. Despite the differences among these four-momentum mapping formats, their common points are still dominant. In the P2G process, the momentum mapping in PIC, FLIP, and hybrid schemes is the same. The material point positions are updated in the same manner across all four schemes.

9. Euler's laws of motion - Wikipedia

   en.wikipedia.org/wiki/Euler's_laws_of_motion

   Euler's second law states that the rate of change of angular momentum L about a point that is fixed in an inertial reference frame (often the center of mass of the body), is equal to the sum of the external moments of force acting on that body M about that point: [1] [4] [5]
