What is Static Friction - Friction, Physics, Class 11 - eSaral

Hey, do you want to know what is Static Friction? If yes. Then keep reading. Static friction The frictional force between two surfaces before the relative motion actually starts is called static frictional force or static friction. If we slowly increase the force with which we are pulling the box, the graph shows that the friction force increases with our force up to a certain critical value, $\mathrm{f}_{\mathrm{L}}$, the box suddenly begins to move, and as soon as it starts moving, a smaller f...
