Friction is directly proportional to pressure.
Angle of repose is equal to angle of friction.
Inertia is a characteristic of an object that resists change in motion. Friction occurs when two surfaces are in contact. I don't see any relation.
There is definitely a strong relation between osmosis pressure and water activity. Osmosis is the movement of water from high pressure to low pressure.
Friction is produced when force opposes motion.
Pressure is defined as force per area
Pressure decreases as height increases and vice-versa.
Pressure = force / area
There is none.
Friction isn't a size. You can increase friction by increasing the pressure on two objects as they pass, or reduce lubrication between them.
Friction exists in the joints between the bones. Cartilage reduces the drag.Also, blood flowing through the vessels causes friction. That is where we get the blood pressure from.
Pressure. Do a Google search on the relation between volcanoes and pressure, or even your question.
Because there is more pressure in the surfaces.
