Grade 9 · Physics
This quiz helps revise “Newton's laws” in Physics for grade 9. It has 25 questions in five categories: First law, Second law, Third law, Everyday forces, Net force & motion. 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.
