No. There are two conditions for equilibrium; both must be met:
1) The sum of all forces must be zero.
2) The sum of all torques must be zero.
no
The equilibrium condition requires the sum of the forces on the body to be zero.
heterogenous equilibrium
Quasi static process - doesn't really exist except in theory. It is a thermodynamic process going infinitely slow. The best example is if you had air at 1C inside a cryogenic thermos and you had add outside the thermos at 1.00000000000001C. The point is is the air inside the thermos would eventually warm up to the slightly warmer air outside the container, but it would take a long long time.
Static and kinetic coefficients
no
Different physical states
Static force refers to the force acting on an object when it is stationary or at rest. It is the force that must be overcome to initiate movement or to keep the object in place. Static force does not change as long as the object remains still.
because the moon doesnt exist, it never has:)
No, an equilibrium exist.
Static charge and static electricity are 2 different terms for the same thing. Static electricity is voltage without current, usually created by friction. Voltage and EMF are 2 different terms for the same thing. When static electricity generates current, it is called a discharge and the static electricity ceases to exist. It has been discharged.
On a long term an equilibrium exist.
