How it works
- Work on your own with a calculator and scrap paper. Try it without notes first: that shows you what you really know.
- Nothing is marked until you press Submit quiz. Until then you can move between questions and change any answer.
- Each question is either right or wrong. When a question has several boxes, every box must be right.
- After you submit, you see your score, a review of every question with a worked solution, and a results sheet you can print or save as a PDF.
- Use \(g = 9.81\ \text{m/s}^2\) and ignore air resistance unless a question says otherwise.
Typing answers
| To enter | Type |
|---|---|
| \(\sqrt{61}\) | sqrt(61) or √61 |
| \(20^2/150\) | 20^2/150 |
| \(22\cos 38^\circ\) | 22cos(38°) |
| \(\sqrt{9.81 \times 30}\) | sqrt(9.81*30) |
| \(-0.75\) | -0.75 |
Each box shows how it read your entry (for example = 7.81), so you can check it before you submit. Type only the number; the unit is shown next to the box.
The quiz
After the quiz
Use your results to decide what to do next. After you submit, the Results by lesson table under your score links straight to the lessons behind any questions you missed.
- Missed a question? Read its worked solution, then revisit the lesson it points to.
- Want more practice? The Practice Lab generates unlimited problems on every skill in this quiz (components, projectiles, tangential and normal acceleration, radius of curvature and converting between systems), each with hints and a full solution.
