Three people push on a door. We determine the net torque.

A 66.0 g ball is launched from a stationary Nerd-A-Pult on wheels. The total mass of the Nerd-A-Pult on wheels is 1,791 g. If the ball moves with a velocity of -351 i + 179 j cm/s right after launching, what is the velocity of the...

Deriving the position equation for an object in simple harmonic motion.

In this video, I explain and demonstrate the hip scour test. More specifically, we cover its rationale and interpretation of results.

In this video, I explain and demonstrate Craig’s test, a special test used in the assessment of femoral anteversion and retroversion, mostly in the pediatric population.

The concept of kinetic energy applied to a stationary, rotating wheel is used to define Moment of Inertia and derive Rotational Kinetic Energy. Moment of Inertia is demonstrated.

0.100 kg and 0.200 kg masses hang from either side of a frictionless #Pulley with a rotational inertia of 0.0137 kg·m^2 and radius of 0.0385 m. (a) What is the #AngularAcceleration of the pulley? (b) What is the #TensionForce in each...

In this video, we will explore several treatment options for plantar fasciitis including forms of self-manual therapy and stretches of the plantar fascia.

This video discusses the importance of students publicly communicating their learning experiences through various forms of demonstration, such as letters to parents, articles in community newspapers, or performances. It emphasizes the...

The relationship between wavelength and frequency is determined. The number of waves, wavelength, and wave speed at each standing wave frequency is determined. The wave speed is measured independent from the standing waves.

In this video, I explain and demonstrate a treatment for thoracic outlet syndrome (TOS), specifically for individuals who demonstrate a (+) Cyriax release test.

The wheel of a bike rotates exactly 3 times in 12.2 seconds. What is the average angular velocity of the wheel in (a) radians per second and (b) revolutions per minute?

Billy analyzes ABS brakes to show the difference between Rolling without Slipping and Rolling with Slipping. He also answers the question in the title of the video, but why would I write that in the description?

From a tuning fork, to a speaker in slow motion, this is a close look at what sound is. Both linear and spherical wave fronts are animated. The human audible range is demonstrated.

A cylindrical space station with a radius of 115 m is rotating at 0.292 rad/s. A ladder goes from the rim to the center. What is the magnitude of the centripetal acceleration at (1) the top of the ladder, (2) the middle of the ladder,...

The equation for the harmonic frequencies of stringed instruments is derived. Harmonic numbers and fundamental frequency are defined. A guitar is used to demonstrate harmonic numbers.

Mr. Fullerton of APlusPhysics.com makes a guest appearance as a floating head to help us learn about Elastic Potential Energy. Several examples of objects which store elastic potential energy are shown and one example of stored elastic...

In this video, I explain and demonstrate the Romberg and Sharpened Romberg test, two related balance tests that are used in the assessment of sensory organization of balance.

Humans are best for demonstrating Tangential Velocity and understanding that it is not the same as angular velocity.

Yes, water stays in the bucket. Would you like to know why? Watch the video and learn!

The Women of Standing Rock part 3/8: This video captures the intense standoff between Native American protesters and law enforcement during the North Treaty camp raid. It highlights the peaceful resistance of the protesters and their...

Standing longitudinal waves are demonstrated and compared to an animation to help with understanding what the heck is going on.
