Lesson 4.2 - Universal Gravitation

 Lesson 4.2 - Universal Gravitation

In this lesson, we look at Newton's understanding about how gravity worked.  We start out by looking at how Newton got to that point by looking at Kepler's Laws of Planetary motion.  Don't worry about those though.  We will not be applying them to anything, we just need to know them.  We then look at Newton's Law of Universal Gravitation and how it applies in various scenarios.  You finish off the lesson by applying universal gravitation to planetary motion to show how we can predict the motion of planets and celestial objects using universal gravitation. When you are done going through the examples, you can work on Assignment 4.2.

Here is the link to the lab activity that we will be doing for this app.

Physics 30 Afternoon Block - Unit 3

 You are to begin Unit 3 at home over the next couple of days. Print off the notes for unit 3, located here. I have narrated the first couple of lessons in Unit 3 and recorded myself solving the examples in the notes.  I will link the powerpoint here.  I recommend that you download the powerpoint and play it from powerpoint.  Do not simply preview it from the google drive folder. The narrations might not play properly then.  Here is what you need to finish and what slides to go through.  This is for both groups, alpha and omega.

Friday, May 7

        Lesson 3.1 - Work - slides 1-12 - Assignment 3.1

        Lesson 3.2 - Power - slides 13-20 - Assignment 3.2

Monday, May 10

        Lesson 3.3 - Kinetic Energy - slides 21-32 - Assignment 3.3

        Lesson 3.4 - Potential Energy - slides 33-40 - Assignment 3.4

As well, the alpha group - make sure to prepare for your Unit 1 Exam on Tuesday, May 11. Good luck with your finals and if you have any questions about physics, make sure to email me.
