2. Momentum - Wikipedia

   en.wikipedia.org/wiki/Momentum

   For example, a 1 kg model airplane, traveling due north at 1 m/s in straight and level flight, has a momentum of 1 kg⋅m/s due north measured with reference to the ground. Many particles The momentum of a system of particles is the vector sum of their momenta.

3. 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]

4. Equations of motion - Wikipedia

   en.wikipedia.org/wiki/Equations_of_motion

   Galileo deduced the equation s = ⁠ 1 / 2 ⁠ gt 2 in his work geometrically, [4] using the Merton rule, now known as a special case of one of the equations of kinematics. Galileo was the first to show that the path of a projectile is a parabola. Galileo had an understanding of centrifugal force and gave a correct definition of momentum. This ...

5. Constant of motion - Wikipedia

   en.wikipedia.org/wiki/Constant_of_motion

   Examples of integrals of motion are the angular momentum vector, =, or a Hamiltonian without time dependence, such as (,) = + (). An example of a function that is a constant of motion but not an integral of motion would be the function C ( x , v , t ) = x − v t {\displaystyle C(x,v,t)=x-vt} for an object moving at a constant speed in one ...

6. 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 ().

7. Position and momentum spaces - Wikipedia

   en.wikipedia.org/wiki/Position_and_momentum_spaces

   Momentum space is the set of all momentum vectors p a physical system can have; the momentum vector of a particle corresponds to its motion, with dimension of mass ⋅ length ⋅ time −1. Mathematically, the duality between position and momentum is an example of Pontryagin duality .

8. Impulse (physics) - Wikipedia

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

   t 1 and t 2 are times when the impulse begins and ends, respectively, m is the mass of the object, v 2 is the final velocity of the object at the end of the time interval, and; v 1 is the initial velocity of the object when the time interval begins. Impulse has the same units and dimensions (MLT −1) as momentum.

9. Vis viva - Wikipedia

   en.wikipedia.org/wiki/Vis_viva

   Leibniz accepted the principle of conservation of momentum, but rejected the Cartesian version of it. [2] The difference between these ideas was whether the quantity of motion was simply related to a body's resistance to a change in velocity (vis inertia) or whether a body's amount of force due to its motion (vis viva) was related to the square ...
