WebDistance covered by the object d = 22m. Acceleration due to gravity g = 10ms -2. The formula to find coefficient of friction given velocity and distance is. Substituting the values of the given terms in the above equation. µ = 0.38. The formula to calculate friction is. F f = µmg. F f = 0.38×10×2. F f = 7.68N. WebA high coefficient of friction produces more friction. Normal force ( F N F_N F N F, start subscript, N, end subscript ): squeezing surfaces together more tightly increases the friction. This is one reason why heavy objects are harder to slide across the ground. family member tree
