Hey Everyone,
Here is a breakdown of the lessons I want you to go through on your own at home on your day away from school. Remember that it is not a day off and you need to be responsible for going through the material and working through the assignments. You can have a look at the powerpoints if you want, but you should have notes that are filled in. All you need are the examples. I will link videos of me solving them below. Go through the videos and fill in the examples in your notes as you do. When you are done the examples, go ahead and try the assignments associated with that lesson. *Note - Some of these videos you might not be able to play in your browser unless you have the right plug in. They are all .mp4 video files. It is ok to download them and play them on VLC media player or any other such media player.
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.
Lesson 5.1 - Charges and Coulombs Law
We begin Unit 5 with a review somewhat of the electricity unit in Grade 9 science. This then leads to an examination of the forces acting on charges that would cause either an attractive or repulsive force. This is called Coulombs Law and we look at a couple of examples how to use the equation in different scenarios. When you get done going through the examples in the videos, work on Assignment 5.1
Lesson 5.2 - Electric Fields and Electric Potential Difference
In the second lesson of Unit 5, we look at electric fields and how to determine their strength. As well, we will also begin to look at energy in electricity, particularly electric potential difference, also known as voltage. There are a couple of examples that you can look at and when completed, work on Assignment 5.2.
If you have any questions at any time, feel free to email me. You can always ask in me class the next day as well. I will definitely take time to take up these questions in class.
