This photo was taken by me from a rare 1729 edition of Isaac Newton's famous The Mathematical Principles of Natural Philosophy. This was the first edition of the book to be printed in English, based on a translation by Andrew Motte. Newton first published the book in 1687, in Latin. He died in 1727, just before the English translation was released.

What is a force?
What forces are acting on you?
A booklet of all of your Newton's Laws comic strips. (Warning: Large file!)
-watch and interact with this simulation demonstrating Newton's 2nd Law (worksheet) -- you can sign in using your school Google account; you may also be able to open the simulation without signing in by opening the simulation from this page
-Homework - complete all three web-based activities above, including the attached worksheet
-complete an online investigation of Newton's 2nd Law -- complete this at home
-differentiate between mass and weight
-Homework - draw a comic strip that illustrates each of Newton's 3 Laws of Motion; each of the laws should be clearly identified within the comic; draw it on a sheet of standard 8.5x11 paper, landscape-mode; it should take up most of the page; color it and put your name on it (and please make it fun or interesting!) -- other people will see your comic, so make something you are proud to show off - DUE: first class after weekend
-Do you have questions about Newton's 3 Laws? This online book provides a good explanation. And so does this website. [Connecting the First and Second Laws.]
-practice calculating the total force upon and acceleration of various objects
-use trigonometry to incorporate forces that are not aligned with our x and y axes
-calculate the acceleration of an object with unbalanced forces, including angled forces (key)
-discuss how to calculate the friction force (notes on friction; just read the first page)
-use this simulation to explore static and kinetic friction (access here, if needed; it's the first Interactive)
-quiz over using free-body diagrams and F=ma to work out the acceleration of a body or to work out unknown forces
-homework - complete this packet of problems (solve for all forces and find acceleration) - (answer key)
-test Newton's Second Law in the laboratory (lab instructions); we'll finish this next class
-finish the Second Law lab
-calculate the acceleration of a box sliding down a hill
-there might be time to work on the Circuits Project
-homework - complete the test review
-you will choose a consumer product that uses an electromagnet for "part 2" of the Circuits Project: Electromagnetism in the Real World; this portion of the project involves independent research on your product and the creation of a "digital display"; it, too, will be due 4/24-4/25
-list of students and their chosen products (1st pd) (7th pd)
-work on the Circuits Project (ideally, you'll be done with the circuits and using today to work on the Electromagnetism part of the project)
-use this form to submit your digital display link by Tuesday night for A day and Wednesday night for B day
-the Circuits Project is due; interviews will be conducted during class
-each student should review the Electromagnetism digital display of
one classmate and fill out this form; review the student that is two lines below
you on the list -->
-locate your classmate's digital displayhere (1st pd) andhere (7th pd)
-after reviewing your classmate's digital display, please view this powerpoint on
electromagnetic waves and complete this related notes sheet
-we begin out last unit of the year: Optics, Light and Modern Physics
Read about electricity generation and distribution!

Humanity's first photo of a black hole was released to the public on April 10, 2019. The image was captured by a collection of radio telescopes, scattered across the Earth. The data they collected took about two years of processing, resulting in this blurry yet magnificent image!
Spectroscopy is the branch of science concerned with the investigation and measurement of spectra produced when matter interacts with or emits EM radiation.
Astronomers are interested in the spectra of stars, as it allows them to determine the chemical composition of those stars. But other scientists also use spectra. Biochemists, for example, sometimes study the absorption spectra of compounds that are exposed to UV, visible and IR radiation.
Here is a bit about UV and visible spectroscopy from an Organic Chemistry textbook. It's complicated, but it shows you that certain phenomena are important in multiple branches of science.
