Soil erosion is a widespread problem in rural and urban Queensland. If we want to save our soils, we need to understand the different types of erosion that can occur. Queenslandâs high intensity summer rainfalls represent a significant risk of erosion by water.
Lagrangian function. Lagrangian function, also called Lagrangian, quantity that characterizes the state of a physical system. In mechanics, the Lagrangian function is just the kinetic energy (energy of motion) minus the potential energy (energy of position).
Other Lagrangian Points. There exist altogether 5 Lagrangian points in the Sun-Earth system and such points also exist in the Earth-Moon system. Among these, the most attention has been given to the two stable points L4 and L5, located in the Moon's orbit but off the position of the Moon (see picture).
