1. CHAPTER 1 + IN T R O DU C T I O N TO PHYSIC S

2. + S C IEN CE  systematized or organized body of knowledge based on observation, experimentation and study.  comes from the Latin word - knowledge or knowing Scientia

3. + BRANCHES OF SCIENCE  Social Science  Physical Science

4. + BIOLOGICAL SCIENCE ex . Biology , Botany , Zoology, Ornithology  deals with the study of living things

5. + SOCIAL S C IEN CE Ex . History , Economics , Political Science  Study of human behavior and societies

6. + PHYS I C AL SCIENCE  d e a l s with the s t u d y o f n o n- l i vi n g t h i n g s , t h eir composition, nature c h a r a cte r is ti c s, the changes They have undergone and The factors affecting these changes

7. + BRANCHES OF PHYSICAL SCIENCE  C he m i s t r y - the study of “matter”- i ts c o m po s iti o n, properties, structure and the changes it undergoes.

8. + BRANCHES OF PHYSICAL SCIENCE  P h y s ic s - the s ci e nce of m a tter a nd e n e r g y a nd the i r i n te r a cti o n with e a ch other.

9. + BRANCHES OF PHYSICAL SCIENCE Astronomy-  Study o f the u n i v e r s e a nd the heavenly bodies.

10. + BRANCHES OF PHYSICAL SCIENCE  Geology- deals with the composition of Earth materials, Earth structures, and Earth processes

11. + BRANCHES OF PHYSICAL SCIENCE  Meteorology- study of the atmosphere and how processes in the a t m o s p h e r e determines Earth’s weather and climate

15. What is MEASUREMENT? 15 Measurement

16. 16 Measurement Is an integral part of Physics… Measurement is defined as the act of measuring or giving the size of something ..

17. Have you ever wonder how measurement started? 17 How do they measure something?

18. Why do we need to be able to measure things? To make sense, all measurements need both . . . Any Ideas? Suppose we wanted to measure a 2 x 4 for building a house. Numbers by themselves don’t make sense. A board is 350 long . . . . A board is meters long . . . . Units by themselves don’t make sense. A Number and a Unit!

19. Measurement System Comparisons All Measurement systems have standards . Standards are exact quantities that everyone agrees to use as a basis of comparison. MEASUREMENT ENGLISH SI Units LENGTH Yard / Inch Meter / Centimeter MASS Ounce / Pound Gram / Kilogram VOLUME Quart Liter TEMPERATURE Fahrenheit Celsius / Kelvin TIME Second Second

20. Measurements are easily understood by all scientists Measurements are easier to convert than the English system Scientists use the SI System worldwide because: Why use the SI System? In the U.S. we use the English or Standard System, most of the rest of the world uses the Metric or SI System. The SI (International System of Units) system is the form of measurement typically used by scientists.

21. In the English system you have to remember so many numbers . . . 12 inches in a foot 3 feet in a yard 5,280 feet in a mile 16 ounces in a pound 4 quarts to a gallon The SI System is based on the number 10. In the SI System you only have to remember one number.

22. The SI System uses the following prefixes: This system works with any SI measurement. The UNIT becomes whichever type of measurement you are making. (mass, volume, or length) It is the same system regardless if you are measuring length, mass, or volume. Kilo 1000 Hecto 100 Deca 10 UNIT 1 Deci 1/10 Centi 1/100 Milli 1/1000

23. It works for all types of measurement. If your measuring . . . Volume then it is the liter (deci liter , hecto liter , etc.) The first part of the term indicates the amount, the second part indicates the type of measurement. centi gram Mass then it is the gram (centi gram , milli gram , etc.) Length then it is the meter (kilo meter , deca meter , etc.) kilo gram

24. To Measure or not To Measure Measurements help us describe the world and everything in it. 24 WHY Measure? Measurements can describe length, volume, weight, time, temperature, and countless other properties.

25. Things to Remember All measurements need a number and a unit ! Basic units of Measurement ( meter, liter, gram) How to convert metric units? Measurement describes almost everything MEASUREMENT means… the act of measuring or giving the size of something ..
