James King Phy1 W/Lab NOV17 Mr. Robert Hill Module 1 Homework: 1. The first step in the scientific method according to Paul Hewitt is to identify a question. In this scenario our question is whether or not a iron plate that has a hole cut in the center will get larger or smaller when the plate is heated and expansion occurs. The second step is to formulate a hypothesis regarding the proposed question. The third step is try and predict the outcome or outcomes of the hypothesis. The fourth step is to test the hypothesis through various experiments and to document the findings. The fifth step involves combining all the information you have gathered i.e. your hypothesis, your predications, your experiments, and the findings. All these combine to create a explanation of the entire process and the outcomes. 2. When we compare Aristotle’s ideas regarding motion to those of Galileo, and Newton, we see there are many differences. According to Paul Hewitt in his textbook Conceptual Physics, Aristotle believed “that a moving object must be propelled by a steady force”. Aristotle believed that nothing could move without a steady force acting upon it. Therefore, in the absence of a steady force acting upon it, an object was in its natural state of rest. Galileo came along and completely disagreed with Aristotle’s ideas about motion. Galileo looked at it from a different perspective. Galileo believed that something could continue moving if there was nothing

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
