Matter, forces and energy — harder questions

The harder half of the same exams: questions on matter, chemical reactions, forces and energy that take a step of reasoning rather than a fact recalled.

  • 正面 Franklin wants to know how fast he runs different distances. He uses a stopwatch to measure the time it takes him to complete a 50-meter, 100-meter, and 200-meter race. How can he calculate his speed for each race?
    背面 Divide the distances by the times
  • 正面 A girl walked for 30 minutes. She noticed that she traveled farther in the first 15 minutes of her walk than in the second 15 minutes. What can she conclude about her walk?
    背面 Her average speed was faster during the first half of her walk
  • 正面 Which part of an atom occupies the majority of the volume?
    背面 Electrons
  • 正面 Which characteristic of the asthenosphere helps explain the evidence of crustal-plate motion?
    背面 The semiliquid physical state

此牌组在导入时经过修改: A subset of the questions was selected and each multiple-choice item was turned into a card: only the text of the correct answer is kept, the distractors and the option letters are removed. Questions that point at material the card does not carry, that describe the answer grid rather than the world — including every bare “Which is…” and every comparative superlative — that are negative, or whose answer does not stand on its own, are all dropped. What survived was read and what read badly was named and removed in the connector source. The deck is built from the questions of a single science domain, recognised by an explicit list of words: a question that touches two domains, or none, goes into no deck at all. Whitespace is normalised and flattened chemical formulas are given their subscripts back (H2O → H₂O); no word is rewritten.
