Question
What is the difference between static friction and sliding friction? For' a given pair of objects, which of the two is greater?
✓
Answer
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 friction is greater than sliding friction because more force is required to remove the object from rest state into dynamic state. Once the object comes into motion, it is easier to keep the object moving by applying comparatively lesser force.
