Explain the difference between static friction and kinetic friction. Which is greater?

Open in App

Solution

Static friction is always greater than kinetic friction because the coefficient of static friction is greater than the coefficient of kinetic friction.
Difference between the static friction and kinetic friction -
Static friction Kinetic friction
Static friction acts between the surface of the bodies which are at rest.
Coefficient of static friction is greater.
Kinetic friction acts between the surface of the bodies which are in motion.
Coefficient of kinetic friction is less than static friction.
