When you put your hand out the window of a moving car, you feel a force pushing against you called drag. This force opposes a moving vehicle, and it's part of the reason why your car naturally slows ...

Piling up: this image shows water flowing from left to right past a partially submerged sphere. A pile up of water is clearly seen to the immediate left of the sphere. (Courtesy: Harris Lab) ...

PROVIDENCE, R.I. [Brown University] — One of the most common and practically useful experiments in all of fluid dynamics involves holding an object in air or submerging it fully underwater, exposing ...

Researchers adapt a novel force measurement technique to uncover the previously unidentified physics at play at the thin air-film gap between water droplets and superhydrophobic surfaces. Microscopic ...

Thrips don't rely on lift in order to fly. Instead, the tiny insects rely on a drag-based flight mechanism, staying afloat in airflow velocities with a large ratio of force to wing size. Researchers ...

The lack of a suitable experimental setup and a limited number of in vitro investigations have impeded understanding of the factors that have important roles in altering the drag force acting on tiny ...

Physics, especially the part about forces and motion, often feels like a maze of confusing concepts and formulas. If you’ve ever stared at a problem about an object moving or a force acting and ...
