Static frictional force magnitude

WebJul 20, 2024 · The magnitude of the static frictional force, \(f_{\mathrm{s}}\), depends on how hard you push. If you rest your hand on a table without pushing horizontally, the static friction is zero. As you increase your push, the static friction increases until you push hard enough that your hand slips and starts to slide along the surface. WebApr 16, 2024 · In fact, as you point at the magnitude of the force of kinetic friction as given by F k = μ k F N The force of static friction, on the other hand, changes depending on the other external forces on the object. To understand why, think of a box sitting still on a horizontal table.
