Actually, the static friction is neverzero.
Kinetic friction is the friction that applies when an object is moving; static friction is the friction that applies when the object is not moving. Static friction must always be greater than, or equal to, kinetic friction.
Sliding friction is always less than the static friction by small amount.

In the reference frame of the interface between two surfaces, static friction does Zero work, because there is never displacement between the surfaces. But it can be positive , negetive or zero with respect to choosen frame of reference.
Static friction
Static friction
Yes, look at "what is static friction?" Static friction is also known as starting friction.
static friction is higher in most cases, if you're talking about the coefficient of static or kinetic friction
Static Friction and Kinetic Friction. Static Friction is what friction that slows you down. While Kinetic friction is sliding friction.
Usually static.
static friction
Yes, rolling friction always reduces the net force to zero.
