The term dynamic contact angle measurements refers to techniques that measure the contact angle during movement.
The contact angle hysteresis can be defined as the difference between these two angles Δθ=θa-θr




  

 

Surface energy can be defined as the energy required per unit area to increase the size of the surface,
and as  such is often quoted in units of mN/m.
Surface energy is usually measured indirectly with contact
angle measurements, which can be a useful qualitative measure.
Quantitative data can also be obtained
by using a variety of different models.(GGFY,Owns,Lewis Acid.zisman plot)
