4. Physics deals with measured quantities

5. Physics deals with measured quantities
Physicists use measuring instruments like rulers, clocks, and balances to assign a number value to physics “quantities”.

6. Physics deals with measured quantities
Physicists use measuring instruments like rulers, clocks, and balances to assign a number value to physics “quantities”.
Physicists classify measured quantities into two major categories according to whether or not a quantity may have a direction or not. What are these two physics quantity types?

87. Writing Large or Small Quantities
Example:
The wavelength of red light is very small. It can be written with all the zero placeholders in expanded form like this:
λ = m (expanded form) λ

88. Writing Large or Small Quantities
Example:
The wavelength of red light is very small. It can be written with all the zero placeholders in expanded form like this:
λ = m (expanded form)
too many digits for most calculators λ
