Science Simulations
If you fill the Coriolis effect 100%, the actual wind on the surface of Earth will appear. High atmospheric pressure and low atmospheric pressure The cause of wind blowing is the difference in air pressure. A high-pressure system has higher … more
Sea and Land Breeze Sea and Land Breeze is a wind that changes its wind direction every day in coastal areas. During the day, a sea breeze blows from the sea to the land, and at night, a land breeze … more
In a potential energy measurement experiment, why should an object be lifted slowly at a constant velocity? When we apply a force to an object and move it in the direction of the force, we say that we have done … more
This simulation ignored the effects of friction. Simple harmonic oscillation In everyday life, we see a lot of movements that repeated the same oscillation. Like below, shaky or suspended objects are doing this oscillation. Clock pendulum An object suspended in … more
Conservation of Mechanical Energy If you look at the roller coasters, you can find something interesting. That’s right. There is no engine on the roller coaster. When we lift the roller coaster to the highest point, then the roller coaster … more
Foucault’s pendulum is a device invented by French scientist Leon Foucault to prove the Earth’s rotation in 1851. The fact that the Earth rotates has been known for a long time, but it is the first example that proves it … more
* Above simulation adjusted the amplitude and wavelength for easy observation. * For your understanding, the frequency modulation range of FM broadcasts is exaggerated. Radio frequency The audible frequency is commonly referred to as ‘sound.’ Sound’s frequency range is about … more
Kids have the know-how, but they can’t tell the principal. “How can you go so high?” Some principles are difficult to describe in words in the world, even if everyone knows. I think one of them is how to ride … more
* We assume an ideal transformer where the excitation current is “0”. Electric transformer A transformer is a device for simply changing the voltage of an alternating voltage (AC). Transformers make it easy to change the voltage of an AC … more
Definite integral In the 2D coordinate plane, a definite integral is a way to find the area of a graph. In a rectangle, the only simple way to get the area is the multiplication of width and height. If the … more
Kepler and Tycho Brahe There is an astronomer before talking about Kepler (Johannes Kepler 1571 ~ 1630). That’s Tycho Brahe. Tycho Brahe (1546-1601) is a famous Danish astronomer. With the development of astronomical equipment, he left a vast amount of … more
