WebLet the object be in an inclined position. Here three forces are acting, one is the gravitational force, normal force, and the last one is the frictional force. Since the object is inclined, it forms an angle with the surface it is in action with. The X-axis of the gravitational force is parallel to the inclined plane, which has the object over it. Web28 de mar. de 2016 · The coefficient of friction should in the majority of cases, remain constant no matter what your normal force is. When you apply a greater normal force, the frictional force increases, and your coefficient of friction stays the same. Here's another way to think about it: because the force of friction is equal to the normal force times the ... WebIn this lesson, we will learn how to determine the acceleration of an object if the magnitudes of all the individual forces are known.
