What is Torque?

This video introduces the concept of "torque" and shows how it can be calculated in many different situations. The video also shows how to use a simple grip strength challenge to experience torque! For more of my videos related to rotational motion SEE BELOW… What is Torque?

The linked video covers the definition of rotational inertia, how to find it experimentally, how to calculate it from different equations, and include 2 example problems. Below are also three videos that allow you to investigate the relationship between the torque exerted on a system and the system’s angular acceleration. This is the experiment I use to introduce my students to the concept of rotational inertia. The linked conclusion discussion explains how the concept of rotational inertia is related to the collected data. For a brief explanation of the lab purpose and procedure watch the first 4 minutes of the conclusion discussion video: https://youtu.be/Fh84QQIpLEw Angular Acceleration Lab (Data Set #1): 1kg total mass at a distance of 0.6m from the axis of rotation https://youtu.be/u6c29tnQCJo Angular Acceleration Lab (Data Set #2): 1kg total mass at a distance of 0.3m from the axis of rotation https://youtu.be/Gots5_IyliM Angular Acceleration Lab (Data Set #3): 0.5kg total mass at a distance of 0.6m from the axis of rotation https://youtu.be/WGW8SmDZ1q4 Angular Acceleration Conclusion Discussion (25 min): https://youtu.be/Fh84QQIpLEw Angular Momentum Introduction (15 min): https://youtu.be/mZAnKu_i7wY Translational and Angular Momentum Conservation (10 min): https://youtu.be/hMB0sbO0Lf4 Orbital Motion (Energy and Angular Momentum) (16 min): https://youtu.be/GVQLuQSVyBc Gravitational Potential Energy in Orbits (17 min): https://youtu.be/o0Fvj6Sf6DU Work Done on Rotating Systems (5 min): https://youtu.be/c4np4BLRk7E Rotational Kinetic Energy (12 min): https://youtu.be/Cg9mdfPN3UI Chapters: 0:00 Grip Strength Challenge 0:35 Student Attempts 1:01 Conclusion #1 (Distance Matters) 4:09 Conclusion #2 4:29 Torque Definition 7:30 Conclusion #3 (Torque and Angles) 8:48 Deriving the Torque Equation 11:28 Two Methods for Finding Torque
