Here, then, we have change of momentum of the sphere, although no force acts on it. In like manner the change of momentum of a rocket and of a locomotive engine is partly due to change of mass. Does it not hence appear that change of velocity is the proper evidence of the action ...
It can be also explained as the force that appears to act on a mass whose motion is described using a noninertial frame of reference, such as an accelerating or rotating reference frame. In fluid mechanics, the inertia is the force due to the momentum of the fluid, and in fluid flow ...
momentum, impulse - an impelling force or strength; "the car's momentum carried it off the road" vigor, vigour, energy, zip - forceful exertion; "he plays tennis with great energy"; "he's full of zip" intensiveness, intensity - high level or degree; the property of being intense ...

Objects at finite temperature emit thermal radiation with an outward energy–momentum flow, which exerts an outward radiation pressure. At room temperature, a caesium atom scatters on average less than one of these blackbody radiation photons every 108 years. Thus, it is generally assumed that any...
By using perturbation theory, we show that an hydrogen atom with magnetic moment due to the orbital angular momentum of the electron has hidden momentum in the presence of an external electric field. This means that the atomic electronic cloud has a nonzero linear momentum in its center of ...
The problem of the interaction between a superficial inhomogeneity and an elastic matrix subjected to both tractions and displacements is considered. It is shown that configurational force and torque act on the inhomogeneity due to the interfacial discontinuity of the elastostatic energy-momentum tensor....
The application of the momentum conservation theorem is shown to have the advantage of less computation, reducing the surface integration of the Lorentz force density to a line integral of the Maxwell stress tensor. The Lorentz force is applied to compute the force density throughout the particles...
At the same time, corporate resources devoted to superannuation issues have reduced due to a greater focus on core business activity and reducing costs. These factors, together with a failure of superannuation funds, on average, to capture the full advantages of sector specialisation, have driven ...
