Download PHY 105 Exam #1 Study Guide: Fundamentals of Physics by Dr. Jay Ansher - Prof. Jay Ansher and more Study notes Physics in PDF only on Docsity! Fundamentals of Physics - PHY 105 Exam #1 Study Guide Section 09 - Dr. Jay Ansher You should use this as a study guide for the material we covered in class, what was in the book and on the homework, and what concepts you should expect to see on the first exam. The exam will be multiple choice, most of the questions asking you to use algebra and formulas to calculate a number. I will provide a cheat sheet of formulas for you to use on the exam. Otherwise, it will be closed book and closed notes. If you can answer the questions here in a general conceptual sense, you should have little trouble picking the right formula and little trouble using it. You should also consider using the end-of-chapter features and sample problems in the book to help you study. Nature of Science What are the characteristics of a good scientific theory? What might cause a scientific theory to be changed or abandoned? What are some historical examples of the combination of observation, and a theoretical model? Why are measurement and mathematics important in physics? Motion and Kinematics What is mass? What is inertia? What is the definition of velocity? How is it related to distance and time? What is the definition of acceleration? How is it related to velocity, distance, and time? How is it related to force? What is the difference between instantaneous and average velocity? What is the difference between instantaneous and average acceleration? How are graphs of position, velocity, acceleration and time related? What does this equation express? v = v0 + at What does this equation express? x = x0 + v0t + 1/2 a t2 What does this equation express? y = 1/2 g t2 Falling and Projectile Motion What is the acceleration due to gravity? How do mass, size, shape, etc. of an object affect this acceleration? What is the range formula and how is it used? What examples can you think of where projectile motion is used in sports? Using Forces and Newton’s Laws What are Newton's 3 Laws? How are they used? What is Newton's 3rd Law? How is it applied to static situations? What is meant by the "net" or "total" force in one direction or dimension? How do Normal, Frictional, Tension forces, and Weight work? How can Newton's laws be used to predict the motion of a system?
