nounpl: rolling frictions
atrito de rolamento
1. The resistance force that opposes the motion of a rolling object on a surface, caused by deformation of the object or surface at the point of contact
Rolling friction is much smaller than sliding friction, which is why wheels are more efficient than dragging objects.
O atrito de rolamento é muito menor que o atrito de escorregamento, razão pela qual as rodas são mais eficientes que arrastar objetos.
2. In physics and engineering, the friction force encountered when an object rolls across a surface without slipping
The bicycle tire experiences rolling friction as it moves along the pavement.
O pneu da bicicleta experimenta atrito de rolamento enquanto se move no pavimento.
This is primarily a technical and scientific term used in physics, engineering, and automotive industries in both Brazil and the USA. It is taught in high school physics classes and is fundamental to understanding vehicle mechanics, particularly in discussions about fuel efficiency, tire technology, and mechanical engineering.
