Grade 7 · Physics
This quiz helps revise “Forces in nature” in Physics for grade 7. It has 25 questions in five categories: Force basics, Net force, Elasticity, Gravity & weight, Friction. 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.
