Movimento Relativo - Relativity for all
    With RELATIVE we may watch an object motion in different, inertial or accelerated reference frames. The program contains four different and independent parts: «car», «plane», «lift» and «collisions». The student may introduce values for the physical quantities before starting the simulation or may simply play with default values. The background scenarios are different, and it is possible to have new scenarios for the observed phenomena.
