Multiplying and Dividing Scientific Notation As you already know, scientific notation (a form of exponential notation) is a concise way to express very small or very large numbers. Consider the speed of light, 300,000,000 m/sec. When writing this value it is very easy to "lose" one, or more, of the zeros. It is much faster and easier to write 3.0 × 108 m/sec or 3.0 E+8 … [Read more...] about Multiplying and Dividing Scientific Notation

## Base Quantities and Derived Quantities Definition, Units Examples

Base Quantities and Derived Quantities Definition, Units Examples Physical quantities are quantities that can be measured. Usually, a specific scientific instrument is used to measure a particular physical quantity. To describe a physical quantity we first define the unit in which the measurement is made. There are many systems of units but the most common system … [Read more...] about Base Quantities and Derived Quantities Definition, Units Examples

## Converting To and From Scientific Notation

Converting To and From Scientific Notation Converting To Scientific Notation To Change from Standard Form to Scientific Notation: Place the decimal point such that there is one non-zero digit to the left of the decimal point. Count the number of decimal places the decimal has "moved" from the original number. This will be the exponent of the 10. If the original … [Read more...] about Converting To and From Scientific Notation

## Correct Scientific Notation

Correct Scientific Notation Scientific Notation Scientific Notation is a way to express very small or very large numbers. Scientific Notation is most often used in "scientific" calculations where the analysis must be very precise. Scientific Notation consists of two parts*: a number between 1 and 10, such that 1≤n<10 and a power of 10. * A large … [Read more...] about Correct Scientific Notation
