Fluids are materials that easily succumb to shearing forces.

Some properties of fluids include:

Viscosity: The property of a fluid that resists the movement of one layer of fluid over another. Viscosity can make basic equations more difficult and can cause turbulence.
Surface tension: The property of a fluid that makes its surface behave like a stretched elastic membrane. This property comes from the cohesive forces between the fluid molecules at the surface.
Specific weight: The weight of a unit volume of a fluid. Specific weight is dependent on acceleration due to gravity.
Compressibility: A type of fluid whose density changes with the application of external force. Examples include gases and vapors.
Incompressibility: A fluid's density does not vary with the application of force. An example of an incompressible fluid is a stream of water flowing at high speed from a garden hose pipe. 

Other properties of fluids include:
Pressure
Density
Temperature
Flow velocity
Speed of sound
