Unit 1
Energy, work, and power
Lesson 1 - Intro
Reading and Questions
Here is the handout that we will be using for the duration of the unit, along with some other resources: Energy, Work, and Power - Student Notes
Next, we will watch the attached videos together in class to introduce the topic. Please answer the questions in the Student Notes as we go!
Part 2 - Sources of Electrical Power
For this lesson, we will be working through pages 6-7 in your Student Notes. We will be working on infographics and presentations that will explain different methods of electricity generation. The reading on the right will help, but your groups will also need to do some independent research.
Homework: complete your presentations and be ready to present by the next lesson.
Reading and Practice:
Questions:
What makes a research source reliable and trustworthy? What are some red flags when we are doing research on the internet?
Guidance: 1 lesson for presentation prep, 1 lesson for student presentations.
Lesson 2
Forces and Mass vs. Weight
In lesson 4, we will investigate the difference between mass and weight, and use digital sensors to collect data that we can use to compare these two important physical properties.
The investigation instructions are on pages 8-9 in the Student Notes.
Lesson 3
Free Body diagrams and Newton's Laws of Motion
In lesson 5, we will consider free-body diagrams, visual representations of Newton's Laws of Motion that tell us the direction and magnitude of an object's acceleration by adding up all of the forces acting on it.
Turn to pages 10-16 in your Student Notes to begin! Homework: Reading and practice.
Reading and Practice Questions:
Additional resource: Free-body diagram simulator.
Lessons 4-5
Kinetic and Gravitational Potential Energy
In lesson 6, we will investigate the conversion of kinetic to potential energy and vice versa. Please open your Student Notes to pages 17-28 for the equations required to handle KE and GPE, and for instructions on the Energy Skate Park activity to the right.

Lesson 6
Power
In this lesson, we will investigate the relationship between power, energy, and time, and students will finally answer the question they've all been asking themselves: how powerful am I really? Batman? Thor? Wonder Woman? Merely Deadpool? 🤔
Page 29-31 in Student Notes
Reading and Practice:
Some food for thought: Batteries are often rated by kilowatt-hours. What is a kilowatt-hour? How many kW-hrs does this sweet Porsche have? What is horsepower and why...WHY???...do we still use it?
NOTE: There will be a short quiz on lessons 5-7
Revision Resources
So, one thing about physics: you really can't spend too much time working on physics problems. So, here are some revision and practice resources.
All of the reading has practice problems. Open up the reading for any section and click on the "View Practice" button.
Unit 1 - Energy, Work, and Poweer.pptxCombo PPT
Ms. Medley's PPT is a combination of Mr. Van Loh student packet, Kognity book information, and additional slides and videos for further clarification.
