About Splung
Splung is an online physics course and help site. It is aimed at students studying general physics at high-school level, A-level physics, or the first year of university. Its main content is topic sections covering physics concepts, with supporting material for revision, homework, and exam preparation.
The site uses mathematics and physics simulations, including Flash simulations and interactive experiments, to demonstrate concepts such as capacitor charge and discharge and conservation of momentum in collisions. A physics forum moderated by a qualified physicist accepts questions on physics and mathematics. Teachers can use the site when planning lessons. The site is still in development. Its current sections cover mechanics, electricity and magnetism, optics, heat and thermodynamics, nuclear physics, cosmology, and waves, and more sections are planned. Pricing is not stated on the homepage.
