Imperial System
![Page 4: P H Y S I C S Chapter 0: Measurements in Physics Section 0B: Scientific Notation & SI Prefixes Objectives: 1)Convert numbers into scientific notation form](https://reader035.vdocument.in/reader035/viewer/2022062217/56649e5f5503460f94b59c59/html5/thumbnails/4.jpg)
SI System
Base-10 for easy conversion 1000 m = kilo-meter
How many meters in 3 kilometers? How many meters in 9 kilometers? How many kilometers in 6000 meters?

Common Units in Imperial
12 inches = 1 foot 5280 feet = 1 mile
How many feet in 3 miles? How many feet in 9 miles? How many miles is 31680 feet?

Scientific Notation
For very large or very small numbers
Large: Speed of light:
300,000,000 m/s
Small: Mass of a dust particle:
0.000000000753 kg
= 3 x 108 m/s
= 7.53 x 10-10 kg

Writing Scientific Notation
1. Put new decimal after first non-zero number
2. Count places decimal moves
Left = Positive
Right = Negative
3. Write in exponent form
3.00000000. m/s
8 PLACES TO LEFT (+)
3 x 108 m/s
![Page 8: P H Y S I C S Chapter 0: Measurements in Physics Section 0B: Scientific Notation & SI Prefixes Objectives: 1)Convert numbers into scientific notation form](https://reader035.vdocument.in/reader035/viewer/2022062217/56649e5f5503460f94b59c59/html5/thumbnails/8.jpg)
Writing Scientific Notation
6380000000. m/s
9 PLACES TO LEFT (+)
6.38 x 109 m/s
0.000000000753 kg
10 PLACES TO RIGHT (−)
7.53 x 10-10 kg
![Page 9: P H Y S I C S Chapter 0: Measurements in Physics Section 0B: Scientific Notation & SI Prefixes Objectives: 1)Convert numbers into scientific notation form](https://reader035.vdocument.in/reader035/viewer/2022062217/56649e5f5503460f94b59c59/html5/thumbnails/9.jpg)
Practice
Write the following in Scientific Notation:
1) 314,000,000,000
2) 986,000,000,000,000
3) 0.000 000 007 5
4) 0.000 000 02
= 3.14 x 1011
= 9.86 x 1014
= 7.5 x 10-9
= 2 x 10-8
