Archimedes' principle: a physics quiz at age 16 level

The last video in the age series. At 16 the material can be proper high school physics, so this one uses two pages on Archimedes' principle, proof included, from a 1913 textbook.

What happens in the video

  1. Photograph the two pages.
  2. Set the age to 16.
  3. Generate the quiz. The questions are noticeably longer.
  4. Get one right, then one wrong, and read both explanations.

At this age the wrong options sit close to the right one. "Equal to the weight of the displaced liquid" against "equal to the total volume of the object" is the kind of choice you can only make if you actually know the principle. That's what makes it useful as test prep instead of a confidence boost.

For older students, mixing a few topics in one session tends to work better than drilling one chapter at a time, as covered in interleaved practice. And for the reasoning behind quizzing at all, read how active recall helps memory.

What's said in the video

Physics for a sixteen year old. Archimedes' principle, from a high school textbook.

Two pages, with the proof and everything.

Set the age to sixteen in the info menu.

Add the photos, and generate.

At sixteen, the questions go deeper, and the wrong answers look a lot like the right one.

Each answer is explained, so a miss still teaches something before the test.
