APPLICATION

Application questions are the most challenging of the three types because they require you to take information from the passage and apply it in some way. Application items frequently require the following: • Use the results of an experiment to evaluate a new situation. • Re-evaluate an experiment in light of new information. • Predict how an author would respond to new information or argumentation. A physics student performed two sets of experiments designed –‘ ‡šƒ‹‡ –Š‡ ˆƒ…–‘”• –Šƒ– ‹ϐŽ—‡…‡ –Š‡ ‘–‹‘ ‘ˆ ˆƒŽŽ‹‰ ‘„Œ‡…–•Ǥ Experiment 1 A stone was dropped from a steep cliff while a camera, mounted on a tripod on the ground, took photographs at 0.1 second intervals. Back in the laboratory, the same procedure was repeated in the absence (nearly) of air inside a huge vacuum chamber. Exp rime t 2 The experiments were repeated (on the cliff and inside the vacuum chamber) using a stone and a cork with identical masses †”‘’’‡† ƒ– –Š‡ •ƒ‡ –‹‡Ǥ – –Š‡…Ž‹ˆˆǡ –Š‡ •–‘‡ Š‹– –Š‡ ‰”‘—† ϐ‹”•–Ǥ  the vacuum chamber, both objects hit the ground together. 5. If part of Experiment 1 were repeated on the moon, where the pull of gravity is one-sixth that of Earth, the stone’s downward speed would increase as it falls (i.e., it would accelerate) but the rate of increase in speed would only be one-sixth as great as on Earth. When the photos taken at 0.1-second intervals on the moon are compared to the photos taken on Earth, the series of moon pictures of the stone will be: A. closer together. B. farther apart. C. identical. D. closer at some times and farther apart at others.

STRATEGY ALERT Application items are often the last items in a set. If you ƒ”‡ Šƒ˜‹‰ –”‘—„Ž‡ ϐ‹‹•Š‹‰ the test, skip the Application items and move on to the next passage, circling back at the end of the test to work on these items. And don’t forget to guess if necessary.
