WebThen if an object is moving across a surface to the right, the friction force should be negative (acting against the positive applied force), and the normal force should be positive (acting against the gravitational force). Let's say: F N = 882 N and μ = 0.600, then: F f = 0.600 × 822 = 529 N, which is positive, when it should be negative. WebSep 1, 2024 · 1.
