Surface Tension

Written by Jerry Ratzlaff on 19 January 2016. Posted in Classical Mechanics

Surface tension, abbreviated as \( \sigma \) (Greek symbol sigma), is the energy or force at the surface of a liquid that holds it together.

\(\large{ \sigma = \frac{F}{l} }\)

Where:

\(\large{ \sigma }\) (Greek symbol sigma) = surface tension

\(\large{ F }\) = force per unit length

\(\large{ l }\) = length of a surface ares that keep sliding side stationary
