This video explains the basic anatomy, physiology, and mechanics behind a heart attack, also known as a myocardial infarction. It discusses how the heart works, the role of the coronary arteries, and the symptoms and treatment of a heart...

The equation for the #AngularMomentum of a #PointParticle is built and visualized. Proof a point particle can have angular momentum is shown. The right-hand rule for angular momentum direction is shown.

We determine what data to collect to create a graph with rotational inertia as the slope of the best-fit line. Then we collect the data and determine the rotational inertia of an irregular shape.

For a pitcher to be his best, he needs to be honest and evaluate himself according to a higher standard. Learn the standard and a simple trick in this video.

A 0.300 kg mass rests on a 0.395 m long, 0.764 kg, uniform wooden plank supported by a string as shown in the figure. If the mass is 0.274 m from the wall and the angle between the string and the plank is 32.1°, (a) What is the force of...

Bunt defenses are critical in baseball. Don't let your team lose a game on a bunt play. Learn how to defend them in this five-video bunt defense playlist

Mark Brent’s coffee run takes a turn for the worse when he has a nasty encounter with Negative Nancy! This lesson will discover the importance of distance-time graphs and displacement-time graphs for representing motion.

Did you know that gears are all around you? You can find them in wind-up toys, bicycles, carousels, cars and trucks, cranes, drills, wind turbines, analog watches, and so forth! If you've looked closely at a moving bicycle, you have seen...

In a universe devoid of anything else, two identical spheres of mass, m, and radius, R, are released from rest when they have a distance between their centers of mass of X. Find the magnitude of the impulse delivered to each sphere until...

101955 Bennu is one of Earth’s closest planetary neighbors – an asteroid roughly the height of a skyscraper, and since late 2018, the place that NASA’s OSIRIS-REx mission has called home. When OSIRIS-REx arrived on...

Angular momentum is used to determine the acceleration of a pulley mass system. two alternate solutions are shown, and the acceleration is demonstrated. This is an AP Physics C: Mechanics topic.

A 5.3 g dart moving horizontally at 16.9 m/s collides with and sticks to a stationary Rotational Inertia Demonstrator a distance of 31.7 cm from the axis of rotation of the RID. What is the final angular velocity of the RID?

Lucy is the first mission to explore the Jupiter Trojans – two swarms of asteroids that share Jupiter’s orbit, leading and trailing the giant planet by sixty degrees. These primitive bodies are thought to be...

Weighted ball programs are popular both in-person and online, but at what age is it safe to start a velocity program in baseball? Are they likely to lead to injury in the near-term or longterm? What are the pros and cons?

Several demonstrations of #AngularMomentumConservation are shown using a rotating stool. The equations is also derived using Newton’s Second Law. Conservation of the direction of angular momentum is also demonstrated.

Learn how to throw harder in baseball and increase your pitching velocity with these five tips. Improve your mechanics and get easy to do drills.

Hand grenades are small bombs that function like firecrackers. They are filled with gunpowder or explosive filler and a fuse. Hand grenades are activated via a mechanical device rather than requiring a person to light them with a match....

A rope is wrapped around a bicycle wheel. The wheel is released from rest and allowed to descend without slipping as the rope unwinds from the wheel. While descending, does the center of the wheel move straight down, toward the left, or...

Three 20.0-gram masses are 9.4 cm from an axis of rotation and rotating at 152 revolutions per minute. What is the moment of inertia of the three-object system? The strings holding the masses are of negligible mass. Rotational Kinetic...
