Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the coherence and simplicity?Coherent derived units simplify scientific equations by eliminating arbitrary numerical conversion factors
2. Why do we use derived units like Newtons and Pascals?They give a consistent, worldwide way to measure force, pressure, energy, and more. This helps scientists and engineers share results without confusion.
3. How is a Newton defined?One Newton equals one kilogram times one meter divided by the square of a second (kg·m/s²). It is the unit for force.

SI Base Units: The seven fundamental units (meter, kilogram, second, ampere, kelvin, mole, candela) from which all other SI units are derived.
SI Derived Units: Units formed by combining SI base units via multiplication, division, and exponentiation to express physical quantities.
Coherent SI Derived Units: Derived units that are formed without any numerical factors other than unity, simplifying scientific equations.
Physical Quantity: A measurable property of a phenomenon, such as length, mass, time, or force.
