9 Main Goal of the Class Upon successful completion of Physics 125 students will: (a) Sketch an accurate free-body diagram of external forces acting on a system, (b) Use Newton s three laws of motion to solve problems involving acceleration and force. (c) Use the Principle of Conservation of Mechanical Energy and the Work-Energy Theorem to solve energy-related problems.

10 Real Goal of the Class Learn to think critically. What does critical thinking mean? Example: we all have certain core beliefs. When you are confronted with strong evidence that your beliefs maybe wrong, do you double down on your beliefs, or do you change them?

11 Critical Thinking Drill A. White card B. Blue card C. Yellow card D. Red card Answer truthfully, don t show other student s your answer.

12 Critical Thinking Drill As the Space Shuttle orbits the Earth, the astronauts inside of the shuttle are able to float in space because A. since there is no gravity in space, they are in a zero gravity environment. B. they and the Space Shuttle are both in a state of free fall. C. they are above the Earth's atmosphere. D. none of the above.

13 Critical Thinking Drill Use the following facts to answer the questions. The space station orbits approximately 200 miles above the surface of the Earth. Isaac Newton stated that the force of gravity that causes the apple to fall to Earth is also the force that keeps the Moon orbiting around the Earth. If the force of gravity is the only force acting on a person, that person will feel weightless. As the space station orbits the Earth, its distance is a.) much closer than the Moon. b.) equal distance to the Moon. c.) much further than the Moon. d.) I don t know how far 200 miles is.

Isaac Newton stated that the force of gravity that causes the apple to fall to Earth is also the force that keeps the Moon orbiting around the Earth. If the force of gravity is the only force acting on a person, that person will feel weightless. Which of the following force keeps the Moon orbiting around the Earth? a.) Gravity. b.) Weak c.) Electromagnetic d.) Strong

Isaac Newton stated that the force of gravity that causes the apple to fall to Earth is also the force that keeps the Moon orbiting around the Earth. If the force of gravity is the only force acting on a person, that person will feel weightless. How far from the surface of the Earth does the force of gravity extend? a.) to the point where the atmosphere ends. c.) to the Moon. b.) infinitely far away from Earth. d.) None of the above.

16 Types of Motion Harmonic motion The type of motion determines the equation. materialworlds.com

17 Motion Laws and Theories Objects at rest remain.....objects in motion.... For every action there is an... Energy is neither....

18 Physics Terms Distance Speed/Velocity Acceleration Force Energy Work Momentum Ave GPA < 2.00 Physics 125 is Unique Biology Terms Mitosis Meiosis Leukocyte Dynein Adenosine triphosphate Ave GPA > 3.00

19 Warning Before Taking the Class A 4.0 GPA student may end up with a C grade in the class. A 2.0 GPA student may end up with an A grade in the class.

20 Best Way to Learn Physics Physics is best learned in small pieces over a span of time. Analogy is like weight lifting.

22 Levels of Knowledge (SLO) Level I: Knowledge/Comprehension Level II: Application/Analysis Level III: Synthesis/Evaluation Levels are complete toward the end of the class period. Levels are graded credit/no credit.

23 Levitation

24 Levitation Question: How does a David levitate? Level I answer: David walks onto street, puts his arms out to the side, and levitates.

25 Level II: Answer

26 Level III

27 Levels of Knowledge and the Exams No credits on Levels I and II are made up on the Exam. No credits on Level III is made up on the Final Exam.

28 Lab 14% 1. Printout the lab from the web page before you go to lab. 2. Complete the lab report before you leave that day s lab, unless you are given an extension.

29 Homework/Lecture Drills 10% Drills are done in class and turned in at the end of the class period. (Make sure to complete the drills, some of the drills will be the Levels!)

32 MacGyver Physics

33 You didn t score a single point today. How did you prepare for the exam? How Did You Prepare? I read a lot of physics books, took lots of notes during lecture, looked at a lot of sample problems. I really worked harder than my score indicates.

34 You did awful. How did you prepare for the tournament? How Did You Prepare? I read a lot of golf books, took lots of notes, watched other golfers on TV. I really worked harder than my score indicates.

35 Examples of How not Study Physics 1. Reading and taking notes on the reading. 2. Recopying the lecture notes so it looks neater. 3. Memorizing the solutions to problems. 4. Assuming you know something without checking it first. 5. Relying too much on equations.

36 Examples of How to Study Physics 1. Read the book, relate difficult concepts using analogies, metaphors, or similes. 2. Rank equations or concepts from most important to least -- Ranking Tasks 3. Analyze the similarities and difference between problems. 4. Relate problems to real life situations. 5. Don t get stuck on the math.

37 Improving Your Grade 1. Exercise 2. Eat a healthy diet 3. Sleep more hours 4. Avoid the comfort zone 5. Be Happy

38 Student Disability Physical Learning Cultural Socioeconomic

39 Cheating and Plagiarism This is not the class to cheat in. Reason is, the risk to reward is not worth it!

40 Lectures The lectures will be geared for the three major learning modalities. Visual Auditory Kinesthetic In addition, I want active learning to take place. (What is active learning?)

41 Planning Ahead Read the section on Unit Conversion. Level I Motion: Unit Conversion with some critical thinking involved.

42 Learning Goals 1. Understand the Scientific Method.

43 I. Physics Physics explains natural phenomena using fundamental laws and theories which can then be used to predict the results of future experiments.

44 Traxoline It is very important that you learn about Lecture should traxoline. Traxoline is a new form of zionter. It is montilled in Ceristanna. The never Ceristannians gristerlate look large like amounts of fevon and then brachter it to quasel traxoline. Traxoline may well be one of this! our most lukized snezlaus in the future because of our zionter lescelidge.

45 II. Scientific Method 1. Observe a Phenomena 2. Develop a Theory 3. Predict/Test Theory 4. Conclusion/Modify Theory

46 Simple Example Observation: 1, 2, 3, 4, 5, 6, Theory: Whole numbers increment by 1. Prediction: 7, 8, 9, 10, What if? Observation: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30 Modify theory

47 Simple Example X Y ? Extrapolated

48 Lab 1. Don t assume something is true. 2. Check the limits. 3. Vary the experimental parameters.

49 1. Observation Ground is flat.

50 2. Theory Ground is flat because Earth is flat. A theory can be tested; if not, it is a belief.

51 3. Prediction If a person sails to the end of the horizon, then he will fall off the Earth. Test Prediction: Someone sails to the end of the horizon.

52 Prediction Failed The ship traveled around the world and returned.

53 4. Modification Earth is round. Observed: Fact
