Induction Exam TODAY!
Homework: Prepare to quickly go through the next unit on more mechanics. Feel free to work ahead.
Watch the following video on universal gravitation. If you remember how to use the formula for the force of gravity, skip the first 3:27, and focus on the calculation of gravitational field. As you're watching this video, relate it to what you know about electric fields and Gauss's Law.
If you'd like to get ahead, watch this brief video about potential energy versus position graphs. We'll use a physical analogy of a hill as a model of how to think about these types of problems. This discussion will help you solve the last problem in the required set below.

Today, if you haven't watched the homework video, start there. Then, we'll watch a brief video about potential energy versus position graphs. We'll use a physical analogy of a hill as a model of how to think about these types of problems. This discussion will help you solve the last problem in the required set below.
Homework: Finish gravitational field problems above. Watch the following video on Kepler's Laws:

Today, you'll work on the following AP problems to check your understanding of orbits and Kepler's Laws.
If you're wondering why 1994M3 part d has two correct answers that seem totally different, check out this article:
Homework: Watch the following two videos - they're the same problem with two different methods which are both useful:
Method 1: small mass dm, constant applied force, finite distance y
Method 2: whole mass remaining, changing applied force, force constant for very small distance dx
📕 2: M 3/23, 📒 4: T 3/24, 📘 7: T 3/24 - heavy rope
