Formula frictional force
WebNewton’s First Law and Friction. Newton’s first law of motion states the following: A body at rest tends to remain at rest. A body in motion tends to remain in motion at a constant velocity unless acted on by a net external force. (Recall that constant velocity means that the body moves in a straight line and at a constant speed.) WebThe friction force is calculated by multiplying the reaction of the surface N and the coefficient of friction k. The formula of the friction force will have the following form: F fr = k * N. In some formulas, the coefficient of friction k is denoted by the symbol µ. The above calculations are valid in the simplest case when the body lies on a ...
