That's a Drag: The Effects of Drag Forces
Undergraduate Journal of Mathematical Modeling: One + Two, 2009 Drag is a force that opposes motion due to an object's shape, material, and speed. This project defined what drag force is, derived the governing equation for drag and listed some applications of drag forces.

Drag Forces in Classical Fields [PDF]
Physical Review Letters, 2010 Inclusions, or defects, moving at constant velocity through free classical fields are shown to be subject to a drag force which depends on the field dynamics and the coupling of the inclusion to the field. The results are used to predict the drag exerted on inclusions, such as proteins, in lipid membranes due to their interaction with height and ...

Collective Ion Drag Force [PDF]
Plasma Physics Reports, 2019 The forces acting on the ensemble of dust grains in a plasma flow are analyzed. It is shown that the nonreciprocal character of the forces results in the appearance of an ion drag force, which depends on the intergrain distance. Results of calculations for two grains and an unbounded hexagonal lattice are presented.

Drag and lift forces when moving in a cohesive granular medium [PDF]
EPJ Web of ConferencesWhen a cylinder moves horizontally in a dry granular medium, it experiences both a drag force and a significant lift force, despite the symmetry of the geometry. The lift force arises due to the unique frictional nature of granular material rheology. The

Drag force to all orders in gradients
Journal of High Energy Physics, 2020 We study the energy loss of a heavy quark slowly moving through an evolving strongly coupled plasma. We use the linearized fluid/gravity correspondence to describe small perturbations of the medium flow with general spacetime dependence.
