WebJul 30, 2011 · Same goes for friction. If there were any friction, the velocity of the bead at the top would be different. I assumed that the loop was fixed and used energy conservations. And i got the correct result. But the book reveals the answer and shows that the normal force is calculated as: N+mg= (v^2/R)*m. WebFriction Force – Solved Examples. Let us answer some problems with a friction force. Problem 1: An object of mass 10 kg is moving through a surface. Compute the friction force if the coefficient of friction is 0.2? Answer: Known variables are, m = 10 kg and μ = 0.2 The friction force formula is, F f = μF n Fn can be computed as, Fn = mg
WebAug 10, 2014 · Here's my solution: speed -= (speed * (1 - friction)) / fps; friction is always a float between 0 and 1, 1 being no friction and 0 being essentially infinite friction.
