These 250 phlashcards cover the basic concepts of the New York State Physical
Setting: Physics Regents Core Guide. The underlined cards are word problems.
The answer key has the core reference for each question. Most are on p16 & 17,
the Standard 4 concepts, with some from p12 & 13, the process skills associated
with Standard 4. Significant figures are used throughout the answer key, with a
few exceptions. There are 22 cards at the end for extra Reference Table practice.
I hope they do help your students with reinforcement and review for the Regents
Physics course. Have phun!
