WebTypes. 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 …
The first general equation of motion developed was Newton's second law of motion. In its most general form it states the rate of change of momentum p = p(t) = mv(t) of an object equals the force F = F(x(t), v(t), t) acting on it, The force in the equation is not the force the object exerts. Replacing momentum by mass times velocity, the law is also written more famously as impact bit caseWebNewton's equation relates shear stress and velocity gradient by means of a quantity called viscosity.
