Static Friction
static friction, friction between two non-moving objects.
Because the friction of molicules rubbing other molicules.
Because you never see objects moving forever. If you roll a ball across a table then a force causes it slow down and stop called friction.
When objects move through fluids, they have to overcome friction acting on them. In this process they lose energy. Efforts are, therefore, made to minimise friction. So , objects are given special shapes.
Fluid friction occurs between layers within a fluidthat are moving relative to each other.
Air friction.
Friction is the force that opposes the relative motion of two objects. When two non-moving objects come into contact the friction between them can have a variety of effects on the objects. For example friction can cause the objects to stick together wear down the surfaces of the objects generate heat and dampen vibrations. Friction can cause two non-moving objects to stick together which can prevent them from moving at all. Friction can also cause the surfaces of the objects to wear down which can change the shape and size of the objects. Friction can generate heat which can cause the objects to become damaged or even destroyed. Friction can also dampen vibrations which can reduce the amount of noise from the objects.Overall friction is a powerful force that can have a significant effect on non-moving objects.
Static friction is the friction between two objects that are not moving relative to each other (eg: a desk on the floor not moving), kinetic friction is the friction between two objects that are moving relative to each other (eg: a desk sliding on the floor)

Static Friction
Static and Kinetic friction, static is the friction between two objects when they are not moving (relative to each other) an example of this is and object staying still on a sloped surface. obviously, kinetic friction is the friction between two objects that are moving and making contact, for example wind resistance.
