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 empirical basis?Physical laws are derived from empirical evidence and repeated experimental verification
2. What is the key discoverer?James Clerk Maxwell unified electricity and magnetism with his equations
3. Why are physical laws important for everyday life?Physical laws help us build machines, cars, phones, and even rockets. For example, the laws of thermodynamics let engineers make engines that run efficiently. Electromagnetism lets us send signals through wires and use computers.
4. How do scientists discover new physical laws?Scientists observe nature many times and repeat experiments. When they see the same pattern again, they write a rule that always works. Sometimes a new rule replaces an old one, like when Newton’s laws were updated by Einstein’s relativity.

Empirical Generalization: A statement based on observed facts and repeatable experiments.
Maxwell's Equations: A set of equations describing the behavior of electric and magnetic fields.
Quantum Mechanics: The physics of subatomic particles, governed by probability and discrete energy levels.
