  2. Newton's laws of motion - Wikipedia

    en.wikipedia.org/wiki/Newton's_laws_of_motion

    Newton's first and second laws, in Latin, from the original 1687 Principia Mathematica The concepts invoked in Newton's laws of motion — mass, velocity, momentum, force — have predecessors in earlier work, and the content of Newtonian physics was further developed after Newton's time.

  3. Philosophiæ Naturalis Principia Mathematica - Wikipedia

    en.wikipedia.org/wiki/Philosophiæ_Naturalis...

    Newton's proof of Kepler's second law, as described in the book. If a continuous centripetal force (red arrow) is considered on the planet during its orbit, the area of the triangles defined by the path of the planet will be the same. This is true for any fixed time interval. When the interval tends to zero, the force can be considered ...

  4. Classical mechanics - Wikipedia

    en.wikipedia.org/wiki/Classical_mechanics

    So long as the force acting on a particle is known, Newton's second law is sufficient to describe the motion of a particle. Once independent relations for each force acting on a particle are available, they can be substituted into Newton's second law to obtain an ordinary differential equation, which is called the equation of motion.

  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. Net force - Wikipedia

    en.wikipedia.org/wiki/Net_force

    One of the essential concepts in physics is that forces can be added together, which is the basis of vector addition. This concept has been central to physics since the times of Galileo and Newton, forming the cornerstone of Vector calculus, which came into its own in the late 1800s and early 1900s. [3] Addition of forces.

  7. 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 are called the equations of a Newtonian dynamical system in a flat multidimensional Euclidean space, which is called the configuration space of this system.

  8. Rigid body dynamics - Wikipedia

    en.wikipedia.org/wiki/Rigid_body_dynamics

    The dynamics of a rigid body system is described by the laws of kinematics and by the application of Newton's second law or their derivative form, Lagrangian mechanics. The solution of these equations of motion provides a description of the position, the motion and the acceleration of the individual components of the system, and overall the ...

  9. Ehrenfest theorem - Wikipedia

    en.wikipedia.org/wiki/Ehrenfest_theorem

    This means, in the case of Newton's second law, the right side would be in the form of , while in the Ehrenfest theorem it is in the form of . The difference between these two quantities is the square of the uncertainty in x {\displaystyle x} and is therefore nonzero.
