'Significant figures' presentation slideshows

What is Physics??. The science of matter and energy and of interactions between the two. Physics is concerned with the description of nature – the description and explanation of natural phenomena in our physical world.

Pearson Prentice Hall Physical Science: Concepts in Action. Chapter 1 Science Skills. 1.1 What is Science?. Objectives 1. Describe how the process of science starts and ends. 2. Explain the relationship between science and technology.

Significant Figures & Scientific Notation. Physics. Significant Figures. Indicate accuracy of measurements Several rules for # of significant figures.. Non-zero digits are always significant. Any zeros between two significant digits are significant.

1. Basic Concepts. Chapter Outline. States of Matter Chemical and Physical Properties Chemical and Physical Changes Mixtures, Substances, Compounds, and Elements Measurements in Chemistry Units of Measurement. Chapter Outline. Use of Numbers

Chemistry 1 – McGill Chapter 3 Scientific Measurement. WARNING: Learn it now...it will be used all year in Chemistry!!!. 3.1 Qualitative measurements measurements that give results in a descriptive, non-numerical form. Examples:. He is tall. Electrons are tiny. Quantitative measurements

Physics for Scientists and Engineers. Introduction and Chapter 1. Physics. Fundamental Science concerned with the basic principles of the Universe foundation of other physical sciences Divided into five major areas Classical Mechanics Relativity Thermodynamics Electromagnetism Optics

 Physics - Ms. Kohler. Warm up: How many mL is 2.34 X10 -12 L?. Date: 7/31/2018 Unit 0: Inquiry Learning Goal:  Determine an appropriate method for data collection and reporting. Yes , you DO have a reflection today.  Physics - Ms. Kohler. Significant Figures.

Accuracy & Precision. Two important points in measurement. Accuracy and Precision At the conclusion of our time together, you should be able to:. Explain the difference between the accuracy and precision Give examples of accuracy and precision. Accuracy.

ORBITAL MOTION. Formulas. Aphelion, perihelion refer to farthest distance, and closest to the Sun. Apogee, perigee refer to farthest distance and closest to the Earth. (peri is the closest). Finding the semi major axis. This is the average distance from the orbiting body.

Unit 2:SCIENTIFIC MEASUREMENT. OBJECTIVES (Don’t Copy!) Convert Between Standard Notation to Scientific Notation Identify Significant Figures & Uncertainty in Measurements Perform Operations with Significant Figures Addition & Subtraction Multiplication & Division

Add to table of contents:. Sig. Fig. Examples Pg. 12 Significant Figures Pg. 13. Significant Figures. Writing numbers to reflect precision. Exact Numbers vs. Measurements. Sometimes you can determine an exact value for a quality of an object. Often by counting.

Significant Figures. What is a significant figure?. The precision of measurements are indicated based on the number of digits reported. Significant figures are the digits that are reported Approximate: weight, height—anything MEASURED; no measurement is perfect.

Measurements: . Every measurement has UNITS. Every measurement has UNCERTAINTY. Accuracy and Precision in Measurements. Accuracy: how close a measurement is to the accepted value. Precision: how close a series of measurements are to one another or how far out a measurement is taken.

Significant Figures. Used to report all precisely known numbers + one estimated digit. Rule #1. Every nonzero digit is significant Examples: 24 = 2 3.56 = 3 7 = 1. Rule #2. Zeros between non-zeros are significant Examples: 7003 = 4 40.9 = 3 . Rule #3.
