viscous force
[ˈvɪs.kəs fɔːrs]
nounpl: viscous forces
força viscosa
1. A resistive force exerted by a fluid on an object moving through it, proportional to the fluid's viscosity and the object's velocity
The viscous force acting on the sphere moving through honey is much greater than the force in water.
A força viscosa atuando na esfera que se move através do mel é muito maior do que a força na água.
2. In physics, the drag force arising from the internal friction of a fluid as it flows or as objects move through it
Engineers must account for viscous force when designing objects that move through fluids.
Os engenheiros devem levar em conta a força viscosa ao projetar objetos que se movem através de fluidos.
This is a technical term primarily used in academic and professional contexts in both Brazil and the USA. It is commonly taught in physics and engineering courses at universities like USP, UFRJ, and MIT. The concept is fundamental to understanding fluid mechanics and aerodynamics in both countries.
