Description A 6:37 minute long physics lecture by Neil McCarthy on deriving the formula µ = tan(θ). This formula can be used in two cases. (a) This formula is used when an object is stationary on a ramp and the angle θ (theta) is such that the object just breaks free from static friction and begins to slide. Meaning any angle smaller than θ will result in the object remaining stationary. The mu calculated will be the coefficient of static friction. (b) This formula can also be used to find the coefficient of kinetic friction if the object is sliding down the hill at a constant speed.
