Friction - Wikipedia

Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body. Internal friction is the force resisting motion between the elements making up a solid material while it undergoes deformation. When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into thermal energy (that is, it converts ...

Pond Filtration - Koi Fish Ponds

These solid plastic beads, at 3 to 5 mm, 1/8" to 1/5", have a surface area per cubic foot of 200 to 300 sq ft / cu ft, which is better than pea-gravel, but 30 to 40 times less efficient than sand. In other words, you might need 30 to 40 bead filters to match the biological efficiency of a single sand filter.

Coefficient of restitution - Wikipedia

The COR will depend on how efficient the soft object is at storing the energy in compression without losing it to heat and plastic deformation. A rubber ball will bounce better off concrete than a glass ball, but the COR of glass-on-glass is a lot higher than rubber-on-rubber because some of the energy in rubber is lost to heat when it is compressed. When a rubber ball collides with a glass ...
