The Course Mechanics! Motion One/two dimensions (graphs) Newton’s Laws Work in addition to energy Momentum in addition to Collisions Rotational Motion in addition to Gravitation Vibrations in addition to Waves Sound The Course Behavior Sharpening pencils/ bathroom Attendance Opening Activities Story Problems on screen or in note packet collected on test days Homework Presentations – in front of class or posted on wiki Notebook Sections- collected on test days Lab Reports Tests 2 Take Home Assignments Unexcused absence = zero Review Test all multiple choice Make-up in addition to Late Work Learning to Read First Grade This course could be one of the most challenging experiences that you will ever have—except as long as first grade. Learning to Read Naming weird little squiggles. (now even Greek!) Differentiate between a b from a d from a p. Sounds as long as each letter even though some letters have multiple sounds, in addition to multiple letters have the same sound (capitals)

Learning to Read First Grade Then one day your teacher put some letters on the board: You tried out several combinations including Kuh-AAH-Tuh. Then suddenly someone shouted out in triumph, “It’s a small furry animal with a long skinny tail that says ‘meow.’” And your world was never the same again. When your car paused at an eight-sided red sign, you sounded out stop in addition to understood how the drivers knew what to do. Learning to Read Nature First Grade If this course works, you will become aware of a whole world you never noticed be as long as e. There are times when you will have to memorize what symbols mean. There will be times when you will confuse things that seem as much alike as b, d, in addition to p once did. And there will be times when you will look at a combination of events in addition to equations helplessly reciting Kuh-AAHTuh in total frustration. So, welcome to one of the most challenging ( in addition to rewarding) courses you have ever taken in your life. If you work at it in addition to let it happen, this experience will change your world view as long as ever. t=rF t=RC Measurements If someone offered to sell a bar of gold as long as $200, you would immediately ask, “How large is the bar” Even when there were st in addition to ard units of measure, they were not the same from time to time in addition to region to region. Later, several st in addition to ardized systems of measurement were developed.

Systems of Measurement Measurements The two dominant systems are the U.S. customary system, in addition to the metric system Thomas Jefferson advocated that the United States adopt the metric system, but his advice was not taken. It is used, however, by the scientific community. The United States is the only major country not to have made the change. Systems of Measurement Measurements The metric system has advantages over the U.S. customary system in addition to was the system chosen in 1960 by the General Conference on Weights in addition to Measures. The official version is known as Le Système International d’Unités in addition to is abbreviated SI. Length Defined in terms of a meter – the distance traveled by light in a vacuum during a given time Mass Defined in terms of kilogram, based on a specific cylinder kept at the International Bureau of St in addition to ards Time Defined in terms of the oscillation of radiation from a cesium atom A meter is about the same length as a mile. a yard a foot. an inch. 2

Systems of Measurement Measurements Even among the familiar units, converting from one unit to another is often a difficult task. For instance, to determine how many inches there are in a mile, we must make the following computation: Which expression correctly converts 60 mph to kilometers per hour x 2 The Metric System Measurements The metric system eliminates the confusion of having many different units in addition to the difficulty of converting from one unit to another. It does this by adopting a single st in addition to ard unit as long as each basic measurement in addition to a series of prefixes that make the unit larger or smaller by factors of 10. kilo = one thous in addition to ; 1 kilometer = 1000 meters The kilometer is about 5/8 mile, so a distance of 50 miles will appear as 80 kilometers. Speed limits appear as 100 kilometers per hour rather than 65 miles per hour.

The Metric System Measurements The Metric System Measurements Because all the prefixes are multiples of 10, conversions between units are done by moving the decimal point—that is, multiplying in addition to dividing by 10s. For instance, because milli means one-thous in addition to th, we can convert from meters to millimeters (mm) by multiplying by 1000. There are 5670 millimeters in 5.67 meters. A Metric Riddle Measurements What are 1012 boo, 103 pede, in addition to 1012 dactyl Answer: A picoboo (peek-a-boo), a millipede, in addition to a teradactyl (pterodactyl).

Significant Figures A significant figure is one that is reliably known In a measurement, the significant figures include the first estimated digit Write 3 to 4 numbers as long as your answers Physics Learning Read the Assigned Reading in addition to your class notes each night Read the story problem Use Solid conceptual underst in addition to ing: seeing a big picture Draw a picture or diagram of the situation Visualize what happens Identify principle list given Apply physics concept to different situations Choose equation (from assigned reading or summary at end of chapter) Could be two equations two unknowns, don’t be afraid to list multiple equations in addition to substitute givens Use prior knowledge Unit Conversions 365 days in a year Basic trigonometry Pythagorean theorem Algebra Physics Learning Successful physics learners: Use multiple approaches to attack problems Use prior knowledge Check to see if the answer is reasonable are the units correct as long as the quantity being found check order of magnitude are signs appropriate in addition to meaningful

Physics Learning Use multiple resources: notes, book, homework, opening activities, etc Work in groups to clarify concepts in addition to their relationships Go beyond symbolic manipulation: plugging in ’s isn’t physics! Do not memorize: learn when & why things work in addition to when they don’t Explicit problem solving strategies: carefully study Serway’s summaries Actively participate! Novice versus Expert Physics Learner Novices see physics problems as object related Experts see physics problems as concept based
