Miscellaneous
1. Scientists use Newton s law of universal gravitation to send probes from Earth to Mars. Which statement best explains why this works? A. Earth and Mars have about the same mass so the probe can transfer between gravity forces easily. B. Natural laws operate the same way on Mars as they do on Earth so the scientists can predict gravity forces in between the two planets. C. There is no gravity force in the space between Earth and Mars so the scientists can easily predict the probe s path. D. As the probe leaves Earth the gravitational force decreased quickly so that Mars gravity can be more easily felt by the probe, drawing it in.

2. Which example shows how scientific knowledge builds as new evidence is gathered? A. Newton improved many early ideas about motion when he developed his three laws. B. Modern scientists use Newton s laws of motion without re-testing them each time. C. High school physics students do a lab that illustrates Newton s laws of motion. D. Hypotheses become theories and theories eventually become laws after enough evidence is collected.

5. Swimmers rely on science and technology more and more to advance in their sport. Newton s 3rd Law of Motion effectively describes how the force applied by a swimmer on the water is equaled by the force of the water on the swimmer. How can this knowledge be found? A. Observations by physicists as well as swimmers give the evidence that swim coaches use. B. Observations by physicists give the evidence, otherwise swim coaches would not know this. C. This knowledge is intuitive to anyone who goes near the water. D. Swimmers can learn this through watching tapes of themselves.

6. Based on his observations, Aristotle taught that objects stopped moving because it was natural for them to do so. Many hundreds of years later, Newton made other observations and explained motion in terms of forces acting on objects. Which statement best explains how modern scientists view Aristotle s and Newton s ideas? A. Aristotle was correct because almost everything that moves stops without any help from outside forces. B. Newton was correct because he had better ways to make measurements to explain what he observed happening. C. Newton is more correct because scientific knowledge builds on past knowledge as new information is learned. D. Neither is correct by today s standards because we now have access to technology to make very precise measurements.
