Sound is vibrating air. But how does the air start vibrating? Created by David SantoPietro.
In this video David gives an introductory explanation of what the quantum wavefunction is, how to use it, and where it comes from.
In this video David shows how to relate the angular displacement to the arc length, angular velocity to the speed, and angular acceleration to the tangential acceleration. Created by David SantoPietro.
Let's look at the properties of materials that cause a resistor to resist the flow of current. Created by David SantoPietro.
David explains how to solve problems where an object rolls without slipping. Created by David SantoPietro.
David explains the rotational kinematic formulas and does a couple sample problems using them. Created by David SantoPietro.
David explains what rotational kinetic energy is and how to calculate it. Created by David SantoPietro.
David explains moment of inertia and the rotational version of Newton's second law and shows how to solve an example problem. Created by David SantoPietro.
Explanation of the second law of thermodynamics.
What happens when there's only one hole? Created by David SantoPietro.
How to find the amplitude, period, frequency, and wavelength for a sound wave. Created by David SantoPietro.
In this video David explains what specific gravity means. He also shows how to calculate the value for specific gravity and use it to determine the percent of an object that will be submerged while floating.
How fast does sound actually travel? Created by David SantoPietro.
Find out why you can make music by blowing into empty bottles. Created by David SantoPietro.
Find out why a flute makes such specific notes. Created by David SantoPietro.
David explains how and why standing waves occur, and well as how to determine the wavelengths for a standing wave on a string. Created by David SantoPietro.
Thin film interference occurs when light waves reflecting off the top and bottom surfaces of a thin film interfere with one another. This type of interference is the reason that thin films, such as oil or soap bubbles, form colorful patterns. Created by David SantoPietro.
Let's work out a few details on how thin film interference works. Created by David SantoPietro.
Some examples of using the thin lens equation. Created by David SantoPietro.
