01: Introduction • Course Code, Credit, Pre-requisite, & Schedule • Course Description • Textbooks, References, & Supplies • Course Objectives • Instructor Information • Grading Policy & Evaluation Procedure • Classroom Policies • Topic List or Course Outline • Attendance – Max Allowed Absences = Number of hours per week times three (ex. 3 hours per week x 3 = 9 max allowed absences) • Tardiness – 2 tardiness = 1 absence • Academic Code of Honor – Will be given a warning, then be directed to the guidance office. Don’t do anything that you’ll be ashamed of in the future. – No Requirements (calcu, summary of concepts, pencil etc.) no Exam • Seating Arrangement – Alphabetical (This is to facilitate better monitoring of grades and attendance.) • Payment for stuff will be used in class – Photocopies of handouts, exams etc. handled by the class treasurer • Pre Lectures – Answer questions and problems before coming to class. – Will be checked randomly. Ticket for the attendance. • Physics Mastery Program – Required to bring all lecture materials – Schedule and participants will be posted on the website • Class Responsibilities Teaching Philosophy – Professors are standards and guides. – If you need any help, don’t hesitate to ASK. Mind reading is not one of my best talents. Walk, Run… Dance How Do I Study Physics? Preparation and hard work are key to any successful learning endeavor. But a major factor not often mentioned is organization. We will discuss several tips for learning physics principles in the following slides. Organization Gather Materials: • Textbook • Loose-leaf Notebook • Scientific Calculator • Hole-punch • Scissors • Protractor (angles) • Scotch Tape • Other Supplies NOTEBOOK Purchase a loose-leaf filler notebook with tabbed sections such as shown here: By organizing all problems, notes, and graded exams, you are always able to review. 1. HANDOUTS 4. EXAMS 2. NOTES 5. LABS 3. PROBLEMS 6. RESOURCES Hole Punch Timely Learning Timely learning is efficient learning. It is better to study an hour each day than to cram on weekends. After each lecture, use your next free period to reinforce your understanding. If you wait until the weekend, you must devote valuable time just rebuilding the information. Outside the Classroom Learning is rarely completed in class. To reinforce teaching, you must work problems on your own as soon after class as possible. Try first, seek help if necessary, review examples, work with others. Working problems is the primary way to learn. Complaints of Beginning Physics Students • Indi magaling teacher ko. • Ang kapal ng textbook! • Indi ako magaling s math. • Wala akong oras. • Dami kasing problema sa: bahay, nanay, tatay, tropa, bf, gf, ff, gff . . . • Sobra naman yung 5 oras na physics.. Dapat 1 oras lng..o di kaya 30 mins.. It’s Your Responsibility! As hard as it sounds, the ultimate responsibility for learning rests with you and no one else. Seek help if needed. Check out other books from the library. Review mathematics. Know when exams are scheduled. Go to consultation hours. Take Action; Never let things outside your control prevent you from achieving goals! Test Anxiety How many times have we heard: “I know the material, but I just can’t perform on tests!” The major way to deal with such fears is through practice and adequate preparation. It’s like shooting free-throws when a basketball game is on the line. You must practice foul shots until they become automatic during times of high pressure. Objectives: 01 • What is Physics? • The Scientific Method. • How Should I Study Physics? Testing the Mars Rover What is Physics? Physics is the science that investigates the fundamental concepts of matter, energy, and space, and the relationships among them. Physics is the most basic of the sciences, underpinning all other disciplines of science, medicine, and engineering. NASA Physicists are problem solvers, often meeting new challenges and developing new theories. Scientific Method Underlying all scientific investigation are the guiding principles of the Scientific Method. 1. Statement of problem. 2. Observation: data collection. 3. Hypothesis: proposed explanation 4. Experimental testing. 5. Acceptance or rejection of hypothesis. An Example of the Scientific Method Albert Einstein once said: “Example isn't another way to teach, it is the only way to teach.” Time t y In this example, we observe a falling object and attempt to predict the distance it will fall in a particular time. The mathematics is largely ignored here in order to just provide the basic steps in the process. Statement of Problem We need to be able to predict the time to fall for a vertical distance y. Time t y By stating the problem, we simply verbalize a need to know or to be able to predict some event. The problem might not be solvable. Observations To address the problem, we organize the data and several trial observations. We measure the time for several drops at different heights. y1 t1 y2 t2 y3 t3 Hypothesis By applying the mathematics and graphing techniques to the observed data, we note that the time of fall is proportional to the square of time, t2. The following equation is written and the constant k is determined from the data. Time t y y kt 2 k 4.9 m/s 2 The hypothesis is now a theory which can be tested. Experimental Testing The next step is for us (and for others) to test the hypothesis: If time t is given in seconds (s), the distance y in meters (m) is: y (4.9 m/s )t 2 2 Each time the distance is predicted correctly, the theory is reinforced. In order for a theory to be accepted, it must be consistent and repeatable by others. Accept or Reject Hypothesis Each time the distance is predicted correctly, the theory is accepted. It takes only one instance of proven failure to cause the hypothesis to be rejected! "No amount of experimentation can ever prove me right, one single experiment can prove me wrong." --- Albert Einstein.
