What is the difference between kinetic and static friction?

when a force is applied on a body to move it kept on a rough surface Friction force begins to act and till the point the body is static. friction force acting is the static friction.But as the body beguns to move static friction is lost and the kinetic friction comes into existance.the similarity in both the friction s is that both of them oppose the motion. and the difference in them is that kinetic friction has a constant value while the static friction varies from a minimum value to a certain maximunm value.

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
