AT the recent Winnipeg meeting of the British Association we presented some results on the terminal velocity of fall of approximately spherical spores, which were not in agreement with Stokes's ...

AT the Winnipeg meeting of the British Association Prof. Zeleny and Mr. McKeehan read a paper on the terminal velocities which they had found when Lycopodium and other small spores fall through air.

Raindrops have been caught breaking the speed limit. Using drizzle detectors, researchers discovered tiny raindrops falling more than 1.3 times as fast as terminal velocity, the speed at which air ...

Estimates are derived on the time and space derivatives of a shallow fluid flow in a channel of approximately rectangular cross section. These estimates depend upon the velocity and pressure being ...

When an object is falling, the two main forces acting on it are weight close weightA force that acts on mass, pulling it down, due to gravity. Weight is a force and forces are measured in newtons (N).
