Physics 100: Torque and Equilibrium of Rigid Bodies
What you'll learn
- How to calculate torque, center of mass, and solve equilibrium problems
Requirements
- Basic understanding of Forces, Vectors, and Newton's Laws
Description
This course covers torque, center of mass, rigid bodies in equilibrium, and the stability of objects. The course is a mix of lectures and problem solving tutorials. Students will learn to how to calculate torque, how to evaluate the center of mass of systems of particles and objects with uniform density. I will teach you how to approach problems and help you develop your own problem solving strategies to become a better problem solver.
Part 1: Torque
- What is torque?
- Understand how torque is different from forces
- Calculate torque using 3 different techniques (standard methods, force components, and moment arms)
- Several example problems to practice
Part 2: Center of Mass
- Learn how to find the center of mass of symmetric objects
- Calculating the center of mass of systems of particles in 1D, 2D, and 3D.
- Practice problems
Part 3: Static Equilibrium
- Conditions for Static Equilibrium
- Problem solving strategies
- Picking the right pivot location
- Several example problems to practice the problem solving techniques.
Part 4: Various Problem Section
- Practice solving Torque and center of mass problems and compare your answers to those of Physics Ninja
- Section contains conceptual questions and algebraic questions ranging from easy to very challenging.
If at any point you don't understand something in my videos please feel free to reach out. I'm always willing to help someone learn. Physics Ninja always has your back!
Happy Learning
Dr. E., Physics Ninja and Expert Physics and Math Teacher.

My name is Dr. E. I'm a physicist and I love teaching math and physics. I obtained my Ph.D. in physics and have been teaching physics now for over 15 years. I currently work as an engineer in mobile consumer electronics and am an adjunct physics faculty at Harper College in Chicago. I previously taught physics for the Princeton Review with a focus on MCAT physics and also trained new physics teachers. Visit my website to learn more about me.
I created these courses to make quality education more affordable. I tutor a lot of students and i know how expensive it can be to find a great, reliable tutor. All of my classes are a mix of lectures, where i review the basic theory and go over key concepts, and tutorials, where i show you how to solve problems and help you develop your own problem solving strategies. The classes contain several example problems for each topic and at the end i typically put together a series of problems ranging in difficulty for you to practice on your own. After you've tried to solve the problems on your own, come watch the videos and see how a Physics Ninja would solve the problem.
All of my courses are comprehensive which means they tend to be longer than other courses. I don't believe you can really learn physics with a 5-hour course covering a semesters worth of physics. To learn physics, you have to practice solving problems, all types of problems, conceptual and algebraic.
I'm committed to all of my students and reply to all emails and questions within 24 hours.
Happy learning!
