Friction
... can easily see that by Newton’s second law, the normal force must be equal to the objects weight, thus the force due to friction depends on the COF and how much the top object is pressing down on the bottom object. The COF is different for different materials and is usually between 0 and 1, but for ...

... these forces. In each case the tension force of the cord attached to the salami must be the same in magnitude as the weight of the salami because the salami is not accelerating. Thus the scale reading is mg, where m is the mass of the salami. Its value is (11.0 kg) (9.8 m/s2) = 108 N. 19. (a) Since ...
