The drag force on an American football
American Journal of Physics, 2003We have measured the drag coefficient on an American football oriented so that its major axis is pointed directly into the wind. The football was suspended from the top of a wind tunnel by bicycle spokes attached to small bearings. The results are similar to the drag coefficients reported by Rouse (1946) for the case of an ellipsoid with major diameter/

The drag force on a moving dislocation. II. Nonzero temperature (thermal drag force)
Journal of Applied Physics, 1979In this part of the paper we consider the effect of the thermal motion of the atoms on the dynamics of a moving dislocation in the linear chain model. We express the effect in terms of a thermal drag force averaged over a lattice step. We compute this drag force for a range of dislocation velocities through computer simulation single-step runs. In each

In this chapter we return to our study of non-adiabatic effects on the forces in collision cascades. In this case we examine the behaviour of the non-adiabatic force on the moving ions. Various attempts have been made to capture the effects of such forces in classical MD simulations by adding a drag force to the ionic dynamics. Our time-dependent tight-

When a steel ball is dropped into a water pool, it will continue to sink with a terminal velocity. If the ball is dropped onto a sandbox, it usually stops suddenly in the vicinity of the surface. How can we classify these two cases in terms of physics? To answer this question, the impact drag force must be a key factor.

Drag, lift, and virtual mass forces
2007The pressure distribution around a particle moving in a continuum is nonuniform. Integrating the pressure distribution over the surface one obtains a resulting force that is different from zero. As shown in Vol. I, Chapter 6.2, the different spatial components of the integral correspond to different forces: drag, lift and virtual mass forces.
