It is difficult to distinguish the independent effects of gravity from those of inertia on a running animal. Simply adding mass proportionally changes both the weight (gravitational force) and mass (inertial force) of the animal. We measured ground reaction forces for eight male humans running normally at 3 m s(-)(1) and under three experimental treatments: added gravitational and inertial forc...
In the Higgs mechanism, mediators of the weak force acquire masses by interacting with the Higgs condensate, leading to a vector boson mass matrix. On the other hand, a rigid body accelerated through an inviscid, incompressible and irrotational fluid feels an opposing force linearly related to its acceleration, via an added-mass tensor. We uncover a striking physical analogy between the two eff...

Abstract Falling coffee filters are a common object of study in introductory physics laboratory classes. They usually used to demonstrate the terminal velocity, and determine how drag force depends on this velocity. However they can also be other ways that air affects motion falling filter. In particular, qualitatively different fluid acts during initial acceleration from rest, causes much less...
In this article, a rectangular cross section breakwater in water of finite depth and infinite domain is studied using the separation of the variables method in regular, sinusoidal waves. Determining the radiation potentials in three degrees of freedom e.g. sway, heave and roll, added mass and damping coefficients of sway, heave and roll motions is obtained. Diffraction problem is solved accordi...
Darwin (1953) introduced a simple heuristic that relates the Lagrangian fluid drift induced by a solid body propagating in irrotational flow to its virtualor added-mass. The force required to accelerate the solid body must also overcome this added-mass. An extension of Darwin’s (1953) method to the case of vortices propagating in a real fluid is described here. Experiments are conducted to demo...
