Physics Formulas & SI Units flashcards — questions people ask

How many cards are in the Physics Formulas & SI Units flashcard deck?
The Physics Formulas & SI Units deck on PuzzlePage has 117 cards. The first 30 are free to play and free to download with no account; the remaining 87 unlock for $2.99 as a one-time payment, or with the $11.99-a-month Study Pack that covers every deck on the site. There are seven SI base units and twenty-two named derived units — numbers fixed by the SI, not chosen to fill a deck. The twenty prefixes here are the ones in classroom use; the SI added four more in 2022.
What is on the physics formulas & si units flashcards?
The seven SI base units, the prefixes, the named derived units and the formula sheet a physics course runs on — each back gives the equation and its unit. Cards look like this: Length → SI base unit: the metre (m); Mass → SI base unit: the kilogram (kg). The deck is written for grades 9–12 and filed under science.
Can I study physics formulas & si units flashcards online for free?
Yes. The first 30 cards of the Physics Formulas & SI Units deck play free in any web browser at puzzlepage.app, with no account, no app and no card details. It works on a phone, tablet, Chromebook, laptop or classroom projector. Practice mode flips through the cards with nothing scored; quiz mode makes you answer each card before it flips, times the run and scores it.
Are the physics formulas & si units flashcards accurate?
Every card in the Physics Formulas & SI Units deck was read and fact-checked by a subject-matter specialist before it went on sale, as was every other card on PuzzlePage — 5,420 cards across 30 decks. The audit found and fixed real defects, and one deck was withdrawn from sale entirely rather than shipped with a known problem. That is the difference from a user-generated flashcard site, where the cards are whatever a stranger typed and nobody is accountable for them.
Can I print the physics formulas & si units flashcards?
Yes. The Physics Formulas & SI Units cards are available as a printable double-sided PDF to cut up, as well as playable in the browser. The first 30 cards are free to download; the full 117-card printable is included in the $11.99-a-month Study Pack.
How should I use the Physics Formulas & SI Units deck to revise?
Start in practice mode and go through the Physics Formulas & SI Units deck once without scoring, to find out which cards you already know — the deck is dealt in a different order every time you open it, so you are recalling the card rather than its position. Then switch to quiz mode, which times and scores the run and lets you re-run only the cards you missed. Use the "flip deck" control to swap which side is the question: recognising an answer is much easier than producing one, so a deck you find easy one way round is usually the harder and more useful drill the other way. Two or three short sessions across a week beat one long one, which is the whole reason flashcards work.
What grade level are the physics formulas & si units flashcards for?
The Physics Formulas & SI Units deck is written for grades 9–12. Because the cards are plain term-and-answer pairs, they are also used outside that band — by adults revising science, and by teachers running them as a whole-class starter on a projector.
