🟢 8: T 3/10🐭 - superposition of force
🟢 8: T 3/10🐭 - superposition of force
Today, we will learn about the principle of superposition by finishing the Coulomb's Law Presentation. Remember that force is a vector quantity.
With the time remaining, you may work on Coulomb's Law problems.
Homework: Finish these problems.
Optional Extra Practice: 📖 Coulomb's Law textbook problems #10, 11, 13, 14, 19, 67.
Optional Enrichment: Demonstrate your ability to apply an old concept to a new concept - superposition of electric force - by doing 📖 Mastering Physics "Ch 20 - superposition of electric force" textbook problems #17, 18, 56, 58, 61, 67, 68. In these problems, you will demonstrate your ability to quantify the force due to a configuration of multiple charges in space.
If you missed class or are looking for additional support on the principle of superposition, watch the following video:

problem solving
Homework: All of the above are due tonight at 10pm if electronic or at the beginning of next class for worksheets.
Optional Extra Practice: If you finish early, you may work on Electrostatics Lab from one of the previous posts. If you finish that, you can continue on to watch the video in the next post.
💚 8: Th 3/12 - electric field
💚 8: Th 3/12 - electric field
Today, we'll discover what a field is by looking a gravitational fields with which we are a little bit familiar. We'll discuss what an electric field looks like and how to represent it with electric field lines. Finally, we will learn how to characterize and quantify the strength of an electric field by expressing the force per Coulomb.
First, you will watch the following video at your own pace. Pause, rewind, re-watch, and take notes. Then, complete the 📄 Electric Field Worksheet (PH).
If you finish early, move on to the next lesson which is longer.
Homework: Finish the 📄 Electric Field Worksheet (PH) which will be collected at the beginning of next class.
