Step 1 · Read the article

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

https://smallwhale.org/articles/classical-mechanics

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 core principles?Newton's Laws of Motion and Universal Gravitation
2. What is the mathematical framework?Differential equations describing motion and forces
3. Why do planets orbit the Sun?Because of the law of universal gravitation, which pulls planets toward the Sun while their motion keeps them moving in a curved path.
4. How does a ball roll when you push it?When you push a ball, a force gives it a push, and the ball keeps moving because of inertia until friction slows it down.

Inertia: The tendency of an object to resist changes in its state of motion.
Momentum: A measure of an object's mass in motion, calculated as mass times velocity.
Conservation of Energy: The principle that energy cannot be created or destroyed, only transformed from one form to another.
Lagrangian Mechanics: A reformulation of classical mechanics using energy concepts (kinetic and potential) rather than forces.
