kinetic friction
[kɪˈnɛtɪk ˈfrɪkʃən]
nounpl: kinetic frictions
atrito cinético
1. The friction force that acts on an object that is already in motion, opposing its movement relative to a surface
When you slide a book across a table, kinetic friction slows it down until it stops.
Quando você desliza um livro sobre uma mesa, o atrito cinético o desacelera até parar.
2. A type of friction with a constant magnitude that depends on the normal force and the coefficient of kinetic friction between two surfaces
The kinetic friction force is calculated using the formula Fk = μk × N, where μk is the coefficient of kinetic friction.
A força de atrito cinético é calculada usando a fórmula Fk = μk × N, onde μk é o coeficiente de atrito cinético.
This is a technical term used universally in physics education across English and Portuguese-speaking countries. It is essential vocabulary in STEM (Science, Technology, Engineering, and Mathematics) courses and appears in textbooks, exams, and scientific discussions in both Brazil and Portugal, with no significant cultural variations in usage.
