In classical mechanics, linear momentum or translational momentum (pl. momenta; SI unit kg m/s, or equivalently, N s) is the product of the mass and ... more
Borda–Carnot equation is an empirical description of the mechanical energy losses of the fluid due to a (sudden) flow expansion. It describes how the total ... more

Horizontal Curves are one of the two important transition elements in geometric ... more
Drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) refers to forces acting ... more
The combined gas law is a gas law which combines Charles’s law, Boyle’s law, and Gay-Lussac’s law. The combined gas law states that:
