Virtual Lesson - Dec 1/2
Lesson 6.2 - Radioactivity and Half-Life
You will learn about the three different types of ionizing radiation. As well, you will learn to how to write a nuclear equation. The concept of half-life will be introduced as well as activity. The lesson will finish with an application of this understanding in a type of technology called radiometric dating. Watch the videos below to learn how to do the examples in the lesson and make sure you go through the powerpoint notes. When finished, you can work through Assignment 6.2
Lesson 6.3 - Nuclear Reactions
You will finish Unit 6 by looking at nuclear reactions and how they produce so much energy (hint: mass defect!). The two main types of reactions will be discussed - nuclear fission and nuclear fusion. There are no examples to go through with this lesson. When you are done going through the notes, work on Assignment 6.3 (and then you are FINALLY done the content in Physics 30!!!)

Virtual Lesson - Nov 27/30
Unit 6 Nuclear Physics Lesson 6.1 - Nuclear Structure and Forces
Today you will begin Unit 6 by looking at the structure of the nucleus of the atom and applying some of the concepts we have been learning throughout the course. The strong nuclear force will be introduced and you will learning how to figure out something called the mass defect and the binding energy, a direct correlation with Einstein's mass-energy equivalence. Make sure to read through the notes and copy down Example 1. When finished, work on Assignment 6.1

Virtual Lesson - Nov 25/26
Lesson 5.5 - Charges moving in a wire
Today you will finish off Unit 5 by looking at how magnetic fields affect charges confined to conductors. This is no different than what we have been examining before, just in a different context. Make sure you read through the notes and go through the powerpoint if you need to. There are some more diagrams and pictures in there if you need more visuals to understand. Copy down the examples and when completed, go through Assignment 5.5.

Virtual Lesson - Nov 23/24
Today you will look at magnetism and how it affects moving charges.
Lesson 5.3 - Magnetic Fields and Forces.
In this lesson, you will examine how magnetic fields are defined and how they produce a force on a charge moving through that magnetic field. This force is 3D in nature and we will learn how to determine the direction of vectors in 3D. This involves utilizing a tool used quite a bit in physics for understanding the third dimension. This tool is called the right hand rule.
Read through the notes and watch the videos below to learn how to do the examples. When you are finished, you can work on Assignment 5.3, which should be in your notes.
Lesson 5.4 - Magnetic Circular Motion.
In this lesson, we learn that because the magnetic force on a charge moving through a magnetic field is acting perpendicular to the direction of motion, this force will produce circular motion. This understanding will lead us into a type of technology called mass spectroscopy, when you can use this motion to help you determine the identity of unknown substances.
Read through the notes and watch the videos below to learn how to do the examples. When you are finished, you can work on Assignment 5.4, which should be in your notes.
Assignment 5.1
Hey everyone - it looks like assignment 5.1 was not in your notes. You could have looked at the powerpoint to find the assignment. I will post it here. Let me know if you have any questions about it. Have a good weekend everyone.

Virtual Lesson - Nov 19/20
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.
