Step 1 · Read the article

Open the article and read it at the level above. Then answer the questions below in your own words.

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 theory of description?Quantum Chromodynamics (QCD)
2. What is the fundamental constituents?Quarks and gluons
3. Why do protons stay together in the nucleus?Even though protons repel each other because they have the same electric charge, the strong force pulls them together so tightly that the nucleus stays intact.
4. How do gluons help the strong force?Gluons are massless particles that carry color charge, and they act like messengers that keep quarks glued together inside protons and neutrons.

Quantum Chromodynamics (QCD): The theory describing the strong interaction between quarks and gluons.
Color Charge: A property of quarks and gluons analogous to electric charge, responsible for the strong force.
Color Confinement: The phenomenon where quarks and gluons are bound within hadrons and cannot be isolated.
Asymptotic Freedom: The property of the strong force becoming weaker at very short distances or high energies.
