What is the difference between static friction and sliding friction? For' a given pair of objects, which of the two is greater?
When the body is in stationary state or is at rest, the frictional forces acting on the body is known as static frictional forces.
But when the object is pushed and it moves, the friction that comes into action is sliding friction.
The static friciton is greater than sliding friction because more force is required to remove the objectf rom rest state into dynamic state. Once the obejct comes into motion, it is easier to keep the object moving by applying comparetively lesser force.
