Why is static friction more than sliding friction?

Best Answers

An alternative view: Highest magnitude of static friction is the magnitude of starting friction. Once a body starts to have relative linear motion, additional work associated with body's linear motion compensates part of starting friction. This produces apparent reduction in starting/static friction between the sliding bodies. read more

Static friction is greater than kinetic friction because of irregularities between the static object and the surface upon which it rests. The irregularities mesh together making it more difficult to start movement than to keep the object in motion. read more

The sliding friction is less than static friction because of the interlocking of the irregularities in the two surfaces. When the object starts sliding the contact points on its surface, do not get enough time to lock into the contact points on the floor. So, the sliding friction is slightly less than static friction. read more

Kinetic friction is less than the static friction because in kinetic friction one object is in moving condition & there is less inter molecular attraction b/w the objects whereas in static friction there is relative motion & thus there is much more inter molecular attraction & this is only why we need less force to move a moving object than the static object. read more
