In this video, I explain and demonstrate several special tests used in the diagnosis of posteroinferior labral tears of the shoulder joint. More specifically, we cover the rationale, interpretation of results, and psychometric properties...

We predict and measure the force of tension acting on a pulley while the system is at rest and accelerating.

Learn about Elastic, Inelastic and Perfectly Inelastic collisions via a demonstration

The equations for the harmonic frequencies of open and closed pipe wind instruments are derived. An animation of a longitudinal standing wave pattern in a closed pipe is shown. Displacement and pressure nodes and antinodes are shown.

Before you can start learning about Forces and Newton’s Laws of Motion, you need to understand inertia and mass. This video defines both and more specifically inertial mass.

In this video, we explore the clinical anatomy of high ankle sprains in addition to the diagnosis using special tests, the clinical presentation, and basics of treatment.

When standing waves are allowed at 15, 30, and 45 hertz on a string, then we should not see a standing wave pattern at 22 hertz. Yet, we do in this demonstration. This explains why.

Reflection with and without inversion caused by fixed and free ends are demonstrated. Standing wave patterns at 5 different frequencies are demonstrated. A standing wave animation is shown to understand to how standing wave patterns are...

What is the angular acceleration of a compact disc that turns through 3.25 revolutions while it uniformly slows to a stop in 2.27 seconds?

All the examples from my video Understanding Uniformly Accelerated Motion.

Projectile motion is composed of a horizontal and a vertical component. This video shows that via a side-by-side video demonstration and also builds the velocity and acceleration vector diagram.

How far does a piece of gum stuck to the outside of a 67 cm diameter wheel travel while the wheel rotates through 149°? A conversion from revolutions to degrees is performed.

Know when and how to use the “Impulse Approximation”.

Bo teaches us about beat frequency. You get to hear what beats sound like, see the constructive and destructive interference wave forms, and learn a practical application of beats while tuning a guitar.

Demonstrating that Circular Motion, when viewed from the side, is Simple Harmonic Motion.

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

Frequency, f, is defined and related to Period, T. Two demonstrations are shown and frequency solved for.

A water rocket in slow motion is used to demonstrate conservation of linear <a href='https://www.flippingphysics.com/conservation-of-momentum-demonstration.html' target='_blank' rel='nofollow'>momentum.</a>https://www.flippingphysics.com/conservation-of-momentum-demonstration.html' target='_blank' rel='nofollow'>momentum. This is an AP Physics 1 topic.

Two equal mass eggs are placed at either end in an egg carton of negligible mass. The egg carton is initially rotated about its middle. If the egg carton is now rotated about one end, what is the final moment of inertia of the eggs...

In this video, I explain the plantar reflex. More specifically, we discuss the reflex arc and how to determine whether or not the reflex is present/normal or abnormal in both adults and in infants.

In this video, I explain the corneal reflex. More specifically, we discuss the reflex arc and how to determine whether or not the reflex is present/normal or abnormal.

A record player is plugged in, uniformly accelerates to 45 revolutions per minute, and then is unplugged. The record player (a) takes 0.85 seconds to get up to speed, (b) spends 3.37 seconds at 45 rpms, and then (c) takes 2.32 seconds to...

A perfectly inelastic collision is demonstrated and analyzed.

Demonstrating, measuring and showing Impulse is Area Under the Force vs. Time Curve
