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 SI base unit equivalence?1 J = 1 kg⋅m²⋅s⁻²
2. What is the work definition (force x distance)?1 J = 1 N⋅m
3. What is a Joule and how is it defined?A Joule is the SI unit of energy and work. It equals one kilogram‑meter squared per second squared (1 kg·m²·s⁻²). It is the work done when a force of one Newton moves an object one meter.
4. Why is the Joule named after James Prescott Joule?James Prescott Joule was an English physicist who proved that heat is a form of energy and that mechanical work can become heat. His experiments helped create the first law of thermodynamics, so the unit was named after him.

International System of Units (SI): The modern form of the metric system, providing a coherent system of measurement for science and industry.
Newton (N): The SI unit of force, defined as the force required to accelerate a mass of one kilogram at a rate of one meter per second squared.
Watt (W): The SI unit of power, defined as one joule per second (1 W = 1 J/s).
Thermodynamics: The branch of physics concerned with heat and its relation to other forms of energy and work.
