Physics Mid-Term Exam Questions CollegeKidPoet July 30, 2016 Abstract Follow all of the guidelines, such as the given number of sentences and showing all calculations (including correct metric units of measure), and make sure every answer you give is the correct answer (with included measurements if necessary). 1 Makayla is talking to Mia about the whether we ever landed on the Moon. Mia says,” I have a theory about that.” Using 3–4 complete sentences, what is wrong with Mia’s use of the term “theory” in this instance? There is a scientific theory in which it deals with a metaphysics and (somewhat) an astrological situation. Theories are used to create hypotheses on a given argument that’s used by and for the theory. In Mia’s case, she can say as many facts as possible about yet may not be able to furtherly detail about either the Moon’s nature and landing or even the Moon itself. Mia can even talk about, as an experiment, what the presence of man being on the Moon would be like to give a possible hypothesis that might actually be a fact. 1

2 Choose ONE of the scenarios below, then de- sign an experiment and describe a procedure to enable you to make an estimate of the av- erage speed. Your description should include the materials you would need and how you would use them to collect the data you need. 2.1 A baseball thrown from outfield to home plate It would be best if you were standing in the center of the outfield on the baseball field, but you can try it on different parts of the outfield as well if you want, and then just throw the towards home plate how you see the outfielders some- times do in a baseball game, which by the way, they have great aim most the time. Anyways, throwing the baseball from the outfield towards to the home plate seems sounds pretty simple thanks to the fact that you’ll be dealing with projectile motions since you can use a still, or initial, position, which is one of the best ways to find the absolute maximum height as well as the time it took to make it from the outfield to the home plate. 3 Give another example of a body moving with constant velocity under balanced forces. Spec- ify the cause of each force on the body and explain how these forces could be changed to affects the body motion. Kristi Yamaguchi and Scott Hamilton are two famous ice skaters who commonly move in a linear pathway, which indicates both the common and constant speed. So, after applying a little force, that will be equivalent, in terms of the magni- tude, to their own frictional force between the ice with themselves. 2

4 If a person weighs 500 N on Earth, what would she weigh on Jupiter, where the acceleration due to gravity is 26 m sec 2 ? Show all work leading to your answer. F = Mg On Earth: g = 9 . 81 m s 2 On Jupiter: g = 26 m s 2 Person’s weight on Jupiter: = 500 9 . 81 * 26 = (50 . 9683995923) * 26 = 1325 . 1783894 1325 . 18N 5 If a freely falling rock were equipped with a speedometer, by how much would its speed readings increase with each second IF it were on a planet where g = 20 m s 2 ? Show all work leading to your answer.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    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.
