3. SCIENTIFIC NOTATION

4. What’s the point?
In physics, we are dealing with measurements that look like this:
6,371,000 m (radius of the Earth)
And those numbers look a lot nicer if we write them like this (in scientific notation):
6.371 x10⁶
Radius of the Earth
Distance from the Earth to the moon
Big G

5. Scientific Notation Expresses numbers as a combination of 2 factors:
A number between 1 and 10
Only 1 digit before a decimal point
An exponent of 10
Negative exponents kick the decimal to the left
Positive exponents push the decimal to the right
