Question

What is difference between sliding friction and static friction?

Solution

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. Static friction is the friction between two surfaces that are not in relative motion with each other, while Dynamic or sliding (aka Kinetic) friction is the friction between two surfaces that are in relative motion with respect to each other.

For example, consider a car that is about to start moving on a road; at that instant, there is static friction between the tires and the road at the area where they meet. This force prevents the tire from slipping against the road as the tires start to rotate. Once the car starts moving, the friction force between the tires and the road (that continues to prevent the tires from slipping against the road) is now known as the dynamic friction force.
Static friction: The friction between the two surfaces of the bodies which are in contact with each other and also at rest relatively is called static friction.

Sliding friction: The friction between the two surfaces of the bodies which are in contact with each other and also at sliding relatively is called sliding friction.

For a given pair of objects, static friction is most of the time greater than sliding or kinetic friction due to the amount of force used to overcome it
