FUNDAMENTALS OF PHYSICS.pptx
- 1. FUNDAMENTAL OF PHYSICS Units, Physical quantities, measurement graphical presentations and Linear fitting of data
- 2. Physics is science concerning matter and energy, and their relationship with each other, it is experimental being studied by physicist by performing experiments to test various physical hypotheses. It could be affirming a discovery or disproving an outdated knowledge.
- 3. In Physics, we use these physical quantities in describing an object properties. These quantities are as follows: 1. Length- is a quantity that shows dimension,; how far, how long how thick and how high
- 4. 1. Length- is a quantity that shows dimension,; how far, how long, how thick and how high
- 5. 2. Mass- it tells us how much stuff there is in the object, how heavy it is.
- 6. 3.Electric current- it tells us how much electrons, tiny particles with negative charge are passing through per unit
- 7. 4. Temperature- it tells us how much energy was in the object.
- 8. 5. Amount of substance- it tells us how many particulates are in the object.
- 10. 7. Time- it tells us how much was change in an instance
- 11. We give credence to physical quantities by affixing them with these things. Can you see it? We use UNITS to define quantities. A unit is a quantity chosen as a standard so we can express how much was in an object, how far we are and so on.
- 14. TWO TYPES OF MEASUREMENT Pride itself foe consistency and easy to use. This system employs the base 10 computation so that it will be easier to convert between units Prides itself in a long history. The people back then has no standardized way of measuring, so they have to improvise. ENGLISH SYSTEM METRIC SYSTEM
- 15. The English or Imperial System is a unit system that was created in Great Britain that unified various standards of measurement across entire country. This system was developed by the creative minds of early natural philosophers and apothecaries or pharmacists.
- 17. The International or Metric System is a unit system designed to simplify the way things are measured, due to the inconsistency of the units used in the English System way before they were unified. Even Great Britain and the US adopted this system.
- 20. Scientific notation is a way of writing very large or very small numbers.
- 21. Conversion- adoption of value whose empiricism in its original form (dollar to peso) we convert units in one system to anther so that we can use them better
- 22. Mario wants carpet that is 18 feet long, but the vendor quotes all prices in inches. How many inches long does the carpet need to be?
- 23. Mario wants carpet that is 18 feet long, but the vendor quotes all prices in inches. How many inches long does the carpet need to be?
- 24. Convert 1.000 km to inches.
- 25. Convert 4.04 x 105 feet to centimeters
- 26. RULES AND GUIDELINES IN WRITING SCIENTIFIC NOTATION Scientific Notation is a way scientists compress extremely large or small numbers into manageable values widely understood by many. Although there are numbers that do not need such configurations, such as 125 or 0.12, scientific notation enables scientists to read and organize values that can help in their research. Writing numbers in scientific notation has two (2) advantages: 1.It saves space, especially when handling extremely large amounts of data using complicated formulae. 2.It allows for faster unit conversions. Guidelines on how to write in Scientific Notation. 1. Coefficient must be greater than or equal to one (1), but less than 10, for there must be only one (1) nonzero digit. Example: 1.23 × 1023 This is CORRECT. 12.3 × 1022 This is WRONG. 0.123 × 1024 This is also WRONG.
- 27. 2.The base is always 10. 3.Exponents in the scientific notation represent the number of digits the decimal point has crossed, and are either positive or negative only. a.The exponent is POSITIVE if the decimal point moves to the left. This means that the number has a large value (see Example a). b.The exponent is NEGATIVE if the decimal point moves to the right. This means that the number has a small value (see Example b). c.Although fractional exponents represent radical values, there is no radical notation in the scientific notation. Example A: a.1.23 × 1023 is 123,000,000,000,000,000,000,000 when expanded.
- 28. b.1.23 × 10−23 is 0.0000000000000000000000123 when expanded. Operations involving Scientific Notations are straightforward. This method utilizes the basic four (4) operations of Mathematics when handling decimal and exponent values.
- 29. LINEAR FITTING OF DATA
- 30. Definition of Terms a. Variables refer to a set of data gathered and observed over the experiment. There are several kinds of variables, each one influencing the other. A variable is a characteristic that can be measured and that can assume different values. Height, age, income, province or country of birth, grades obtained at school and type of housing are all examples of variables.
- 31. b.Axes are the projections of the Cartesian plane that denote and track changes within the observable period of the experiment or research.
- 32. i.The X-axis is the horizontal part of the Cartesian plane that usually represents the independent variable, ii.The Y-axis is the vertical part of the Cartesian plane that represents the dependent variable.
- 33. c. A Curve is a linear representation of the trend that the variables show. d. An Asymptote is a trend line that lies exactly close to one of the axes, but never touches it.
- 34. e.A Cusp is a singular point on a curve wherein a moving point starts to move backward. f.An Inflection Point is a point in a curve wherein the curvature changes.
