We’ve just published Gravity Force Lab 2.0 with a “Constant Radius” feature so that you can change the mass of the objects without changing their size. Thanks to the teacher who suggested this new feature so that students can’t assume size is related to mass.
Explore how light bends when it encounters an interface of two different indices of refraction with the HTML5 Bending Light sim. See how changing from air to water to glass changes the bending angle. Play with prisms of different shapes and make rainbows.
