It can make moving heavy objects easier for example sliding friction you can slide it or rolling friction you can roll the object across some kind of round cylinders or even fluid friction with water running under the object can make it easier.
Static friction stops an object from moving. It is the force between two surfaces that are not moving relative to each other. Once the object starts moving, kinetic friction comes into play.
No, static friction is the force that must be overcome to start an object moving from rest. Kinetic friction comes into play once the object is already in motion, opposing its movement.
An outside force is needed. If friction comes into play (which it likely will), the magnitude of the applied force must be greater than the force of friction acting upon the object in order for the object to move. FYI, the force of friction is equal to the coefficient of static friction times the normal force (equal to the weight of the object).
Having your hands touch. Anything where things aren't moving, they are just touching. If you are asking about Coulomb Friction, static friction is the resistance to movement (sliding) of one object over another when force is applied but there is no movement. Once the objects begin to move in relationship to each other (slide) the force required is lessened and dynamic friction is in play. Static friction requires a greater force to get an object moving, dynamic friction requires a lesser force to keep the object moving.
Centripetal friction helps to maintain the stability of objects moving in circular motion by providing the necessary inward force to keep the object on its circular path. This friction acts in the opposite direction of the object's motion, preventing it from moving outward and maintaining its trajectory.

Static electricity occurs when there is a buildup of electric charge on the surface of an object due to friction with another surface. This charge imbalance can cause sparks or shocks when the object comes into contact with a conductor or a grounded object. Static electricity is more likely to happen in dry environments or when certain materials, like plastics or rubber, are involved.
It slows the object down.
A stationary object does not experience friction if all external forces acting on it are balanced. Friction only comes into play when there is relative motion or an attempt to move the object.
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 comes into play when an object is at rest or stationary and a force is applied to it that is not enough to overcome the force of static friction. The surfaces of the object and the surface it is in contact with must be in contact and in fact.
An object's motion is affected by the initial speed and acceleration and the forces that interact with it, the most important being: Gravity - that is affected by the gravitational constant g - which is affected by altitude; Air friction - that depends on the speed of the object and it's volume and air density; Surface friction - depends on the size of the surface of contact, the force that the object exerts on the surface, the surface and the object's coefficient of friction; All the above forces are proportional to the mass of the object.
