Physics Phenomenon Quiz
Seven quick multiple-choice rounds on cavitation, the Coanda effect and the boundary layer. Each answer comes with a short explanation of what is happening in the flow.
Frequently asked questions
What does the physics phenomenon quiz cover?
Three visual phenomena from the fluid-dynamics explainers: cavitation bubbles forming and collapsing in pumps, the Coanda effect that makes a jet follow a curved surface, and how the boundary layer grows, separates and leaves a wake.
Do I get an explanation after answering?
Yes. Once you choose, the correct option is marked and a short explanation appears below the question, so a wrong answer still teaches you the phenomenon.
How long is a round?
Seven questions, one screen each. You can restart at any time to play the whole set again from the start.
Where can I read these phenomena in full?
Each phenomenon links to a full explainer in the Physics section, such as cavitation bubble formation, the Coanda effect, and boundary-layer formation along a flat plate.
