An interactive lab guides Year 13 students through gravitational potential

“Mapa de potencial gravitatorio” (Gravitational Potential Map) is a Spanish-language web resource for Year 13 (2.º de Bachillerato) Physics. It lets users place up to four point masses and view the potential V (in J/kg) as a two-dimensional colour map, with optional equipotential lines, or as a three-dimensional relief with exaggerated depth so it can be seen clearly; the page makes clear that this is a graphical metaphor and not a real deformation of space.

It also includes an A → B experiment: two points and a test mass are chosen, and the app shows the potential at each point, the potential energies, their change and the work done by the gravitational force. Users can reverse the route and try another path to check that the work does not depend on the path taken.

Its author explained in the group that this time he added a teaching guide so that users are guided along rather than having to discover what to do, and that he finds it very useful for explaining complex concepts visually. The page gives no authorship or licence.
