Understand the forces acting on an object on an incline by analyzing the forces on a “floating block”.

Determine the #Acceleration of a uniform, solid cylinder #RollingWithoutSlipping down an #Incline with incline angle θ. The rotational inertia of a uniform, solid cylinder about its long cylindrical axis is ½MR^2. Assume the cylinder...

The video explores distance-time graphs and how they can help us understand the motion of objects and calculate their speed. Using a specific example of a cyclist's journey, the video shows how to interpret the graph and calculate the...

Learn how to throw a changeup in this video, complete with the best changeup grip for nearly all pitchers. Get a heavy, sinking change-up by using this "modern" changeup grip, which is referred to by some as a discoball changeup because...

In this video I sing "Hänschen Klein". It is a little story about a boy who leaves his home to go find his luck in the world. Subtitles are available in three forms: German only, German with English direct translation, and German with...

We define and discuss how to draw Free Body Diagrams which are also called Force Diagrams. In addition we define the force normal and the force applied. Force of friction and center of mass are briefly discussed, however, a much more...

This video explains what a clinometer is, why it is used, and how to construct and use one. It also provides an example of how a clinometer can be used to measure the height of tall objects without actually measuring them.

10 trials to calculate the coefficient of static friction and how to calculate the uncertainty of this measurement.

In this video, students will learn about six simple machines: lever, inclined plane, wedge, wheel and axle, pulley, and screw. They will understand the basic principles of how these machines work and how they can make our lives easier by...

Resolve the force of gravity into its parallel and perpendicular components so you can sum the forces.

This is an introductory lesson about Uniformly Accelerated Motion or UAM. I show examples of 5 different objects experiencing UAM, some are even in slow motion. We also learn my simple way of remembering how to use the UAM equations.

A hollow sphere, solid sphere, and thin hoop are simultaneously released from rest at the top of an #incline. Which will reach the bottom first? Assume all objects are of uniform density. #RollingWithoutSlipping

Learn more about the six simple machines.

The free body diagram we first learn is not entirely accurate. All of the forces are not drawn from the center of mass of the object. Learn why we start this way and, when we get torque, what the free body diagrams will actually look...

Learn about and see examples of Translational Equilibrium.

This video explains the concept of friction, which is a force that exists between two objects that resists motion. The video discusses the two types of friction, static and kinetic, and explains how they work. It also explains how the...

This live-action video program is about the term Inclined plane. The program is designed to reinforce and support a student's comprehension and retention of the term Inclined Plane through use of video footage, photographs, diagrams...
