ENG 010: Problem Set # 1 The Scientific Method. Question 1 The first step of the scientific method involves: a. forming a hypothesis. b. making observations. c. performing an experiment. d. predicting the result of an experiment Answer: (b) Question 2 Outline the five steps of the scientific method. Question 3 If the results of an experiment turn out differently from what you expected, then: a. the experiment was a failure. b. you should rework your hypothesis c. you need to redo your experiment until you get the expected result. d. you didn't follow the scientific method. Answer (b) Question 4 hypothesis is a. obeyed under any circumstances. b. a theory that has been proved c. a tentative explanation for a natural phenomenon d. a description of a pattern or relationship in experimental data Answer (d) Question 5 Which Aristotelian ideas did Galileo (1) discredited with his “fabled” leaning tower of pisa experiment and (2) demolished with his inclined plane experiments. (REMINDER: The leaning tower experiment involved dropping stones of different masses from a high elevation. The inclined plane experiments involved two inclined planes separated by a horizontal floor. He had observed that the ball rolling down picked up the speed, the ball climbing up lost the speed and ball on the flat middle moved at a constant speed.). Answer.

(1) Objects of different masses reach the ground at different times. He discredited the notion that heavier objects fall to the ground faster. (2) No external force is required to maintain a uniform motion in straight line. In the absence of external forces or friction, the ball moving uniformly continues to move along the straight line path. Question 6.
