Is friction an internal force
Webcoefficient of friction, ratio of the frictional force resisting the motion of two surfaces in contact to the normal force pressing the two surfaces together. It is usually symbolized by the Greek letter mu (μ). Mathematically, μ = F / N, … WebMay 17, 2024 · What is really important about internal forces is that if you have an internal force, its equal and opposite reactionary force points in the opposite direction, and sums to zero. This is why they cannot cause acceleration.
