Hi SOHAWONG! Welcome to PF! :wink:

Solids have friction.

Fluids (liquids and gases) have viscosity.

Both measure the resistance to movement.

The main difference between friction and viscosity is that when an object moves against a solid, the solid stays where it is, but when an object moves through a fluid, some of the fluid moves with the object.

See http://en.wikipedia.org/wiki/Viscosity" for details. :smile:
