Directions: It is important that you provide answers in your own words. Please focus only on information from the text/eBook to create your own solutions. Please do not use direct information from an outside source (especially copying and pasting from an “answer” website). Use of direct information from an outside source is against school policy. All answers will be checked for plagiarism. Instances of plagiarism can result in probation or possible dismissal from the school.

Grading: Please be sure to follow all guidelines (number of sentences/showing all calculations) and to provide the correct metric units of measure. All questions are 5 points. You MUST include units on all your answers.

For any math based questions you must show all your work and explain any numbers that are not clearly understood by the problem. There is a formula sheet for you to use at the end of the exam.

According to Ch.1, use at least two to three completed content related sentences to explain why physics is considered the basic science. Provide at least one example to explain how physics relates to other sciences.
You do work on something when you lift if against gravity. Explain how work relates to gravitational potential energy using at least two complete content related sentences. If the lifted object is released, describe the change in energy. Be sure to define all terms used in both questions.
In terms of momentum change, explain why it is best to “give” when catching a baseball. Provide at least TWO other examples of situations in which you want “give”.

According to Ch.3, write 4 to 5 sentences about what the early scientists from Aristotle to Galileo thought about the nature of motion.
Suppose you are on an airplane moving at high speed. If you flip a coin straight up it will land in your lap rather than a great distance behind you. Explain why this is true and include any laws that help prove your point. Your answer should be at least 3 to 4 complete content related sentences.
What is terminal speed? When a skydiver has reached terminal speed, what is the are resistance equal to? What is the skydiver’s acceleration? Be sure to use at least 3 to 4 complete content related sentences.
A force is a push or a pull. Newton’s third law further defines the meaning of force. Be sure to explain using at least 3 to 4 complete content related sentences.

Provide the time dilation equation found in Section 15.4 of the text. Explain each step of the derivation.
You sit at the outer rim of a Ferris wheel that rotates 2 revolutions per minute (RPM). What would your rotational speed be if you were instead clinging to a position halfway from the center to the outer rim? Be sure to provide at least 3 to 4 complete content related sentences and show any work needed to support your answer.
