Webb16 juli 2024 · Navier · Newton · Stokes. Surface tension is an effect where the surface of a liquid is strong. The surface can hold up a weight, and the surface of a water droplet holds the droplet together, in a ball shape. Some small things can float on a surface because of surface tension, even though they normally could not float. http://hyperphysics.phy-astr.gsu.edu/hbase/surten.html
