  2. Newton's laws of motion - Wikipedia

    en.wikipedia.org/wiki/Newton's_laws_of_motion

    The Euler momentum equation is an expression of Newton's second law adapted to fluid dynamics. [59] [60] A fluid is described by a velocity field, i.e., a function (,) that assigns a velocity vector to each point in space and time. A small object being carried along by the fluid flow can change velocity for two reasons: first, because the ...

  3. 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.

  4. Newtonian dynamics - Wikipedia

    en.wikipedia.org/wiki/Newtonian_dynamics

    i.e. they take the form of Newton's second law applied to a single particle with the unit mass =. Definition . The equations ( 3 ) are called the equations of a Newtonian dynamical system in a flat multidimensional Euclidean space , which is called the configuration space of this system.

  5. Newton's law of universal gravitation - Wikipedia

    en.wikipedia.org/wiki/Newton's_law_of_universal...

    The first test of Newton's law of gravitation between masses in the laboratory was the Cavendish experiment conducted by the British scientist Henry Cavendish in 1798. [5] It took place 111 years after the publication of Newton's Principia and approximately 71 years after his death.

  6. Impulse (physics) - Wikipedia

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

    The SI unit of impulse is the newton second (N⋅s), or the Cupp, [1] and the dimensionally equivalent unit of momentum is the kilogram metre per second (kg⋅m/s). The corresponding English engineering unit is the pound-second (lbf⋅s), and in the British Gravitational System, the unit is the slug-foot per second (slug⋅ft/s).

  7. Acceleration - Wikipedia

    en.wikipedia.org/wiki/Acceleration

    Acceleration has the dimensions of velocity (L/T) divided by time, i.e. L T −2. The SI unit of acceleration is the metre per second squared (m s −2); or "metre per second per second", as the velocity in metres per second changes by the acceleration value, every second.

  9. Newton-second - Wikipedia

    en.wikipedia.org/wiki/Newton-second

    The newton-second (also newton second; symbol: N⋅s or N s) [1] is the unit of impulse in the International System of Units (SI). It is dimensionally equivalent to the momentum unit kilogram-metre per second (kg⋅m/s). One newton-second corresponds to a one-newton force applied for one second.
