In this video Paul Andersen explains rotating object have angular momentum. The angular momentum of a point object is the product of the distant from the center of rotation and the linear momentum. The angular momentum of an extended...

In this video Paul Andersen begins by discriminating between translation and rotational motion. He then explains how a torque is the product of the lever arm and the force perpendicular. The lever arm must be perpendicular to the axis...

This video solves a physics problem that demonstrates how to calculate the net torque acting on a rigid body due to multiple applied forces. It covers the concept of torque, moment arm, and vector summation

Prepare for the AP Physics 1 Exam with this comprehensive review of the second half Unit 5! In this video, we cover torque, rotational inertia, rotational equilibrium, and the rotational forms of Newton’s laws. Learn key concepts,...

Dive into the strategies and tools Cro-Magnon used to hunt and gather food in a frigid, Ice Age Europe. This segment shows the use of sophisticated weapons like the spear-thrower and details the balanced diet that included meat, wild...

Torque basics explained, in this video we quickly learn what is torque and how it is used with worked examples and gears to illustrate the principle in under 2 minutes.

This problem is about the net torque on a cylinder with multiple radii.

This problem is about the equation for the net torque on an cylinder with two radii in static equilibrium.

These are my solutions to the Multiple Choice section of the Mechanics portion of the 1998 AP Physics C released exam. AP® is a registered trademark of the College Board, which was not involved in the production of, and does not...

Calculus based review of moment of inertia for a system of particles and a rigid object with shape, the derivation of rotational kinetic energy, derivations of the following moments of inertia: Uniform Thin Hoop about is Cylindrical...

This video explains the function of the kneecap, also known as the patella, and its role in providing leverage for the quadriceps muscles.

Review of the Rotational Dynamics topics covered in the AP Physics 1 curriculum.

You had a baby! Hooray! Now it's time to stop building ramps and pulleys and it's time to start building baby stuff. You love astronomy so you decide to make a mobile of the solar system. But in order to get everything to balance out, we...

Translational and Rotational motion are demonstrated and reviewed. Torque is introduced via the equation and several door opening demonstrations. Moment arm or lever arm is defined and illustrated.

More spinning things! Records, and wheels, and doors, and other fun things. The equations that govern this kind of motion are just like the ones we learned in kinematics, except they have different symbols. Lots of funky Greek letters in...
