SCIENTIFIC NOTATION

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

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
