Grades 11–12 · Physics
This quiz helps revise “Conservation laws” in Physics for grades 11–12. It has 25 questions in five categories: Momentum and impulse, Rockets and recoil, Work and energy, Energy conserved, Collisions. Questions get harder as the points go up, from 100 to 500.
The 100- and 200-point questions are open here. The rest show only their first words, and there are no answers: all of that is in the game itself.
