We use the inside of a pencil (graphite) to apply different "lengths of pencil" to the circuit. What relationship do you observe between length of graphite and deflection angle? Created by Brit Cruise.
How variation can be introduced into a species.
Every force in our particle system will be represented with a vector.
Using the "virtual ground" idea, we reexamine the inverting op-amp and find a solution much quicker. We apply the virtual ground method to a unity-gain buffer (amplifier with gain = 1). Created by Willy McAllister.

Visualize the Fourier expansion of a square wave. A square wave can be approximated by adding odd harmonics of a sine wave. Created by Sal Khan.
Visualizing, adding and breaking down vectors in 2 dimensions. Created by Sal Khan.
The history of visual telegraphs. Created by Brit Cruise.
Visual understanding of how centripetal acceleration relates to velocity and radius. Created by Sal Khan.
Voltage is a cornerstone concept in electricity. We create an intuitive mental image by comparing voltage to gravity. Created by Willy McAllister.
The output voltage is a fixed fraction of the input voltage. The ratio is determined by two resistors. Created by Willy McAllister.
Learn about the instruments we use to measure voltage and current. Created by David SantoPietro.
Sal introduces the notion of moving fluids and laminar flow. Then he uses the incompressibility of a liquid to show that the volume flow rate (flux) must remain constant. Sal then derives the equation of continuity in terms of the area and speed. Created by Sal Khan.
The formula for the volume of a sphere is V = 4/3 ??r??. See the formula used in an example where we are given the diameter of the sphere. Created by Sal Khan and Monterey Institute for Technology and Education.
