nothing could be held in place.
no fire
You may not get enough friction to stay upright (and you may fall), or to stop (and you may slide into something).
The friction will also double as Friction= (friction coefficient)(normal reaction)
Opposite charges attract. What happens depends on friction and mass of the objects. They may attract strongly enough for motion toward each other, maybe not.
not enough lube
If it doesn't budge, the net force must be zero. What usually happens is that there is a force of friction that opposes the push or pull; as you pull harder, the force of friction increases. At a certain treshold, there is not enough friction (it can only increase to a certain level), and the object starts moving.
Due to friction
Frictional force gets doubled. But coefficient of friction does not change
If the pleura does not secrete enough fluid friction can occur between the corresponding linings (visceral and peritoneum) causing damage to the organ
you die
The things will slide
No. friction produces thermal energy therefore friction produces heat. Rub your hands together and see what happens.
