Web26 de mar. de 2016 · This equation tells you that when you have the normal force, FN, all you have to do is multiply it by a constant to get the friction force, FF. This constant, is called the coefficient of friction, and it’s something you measure for contact between two particular surfaces. ( Note: Coefficients are simply numbers; they don’t have units.) WebA Force can cause an object at rest to move. A Force can also cause a moving object to stop. What is the SI unit of Force? The SI unit of Force is a Newton (N) What is one Newton composed of? 1N = 1kg x (1m/s²) What is the weight of an object? The weight of an object is a measure of the magnitude of the gravitational Force exerted on the object.
