Science Simulations
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 … 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 … 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, … 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 … 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 … 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 … 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 … 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 … 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 … more
* You have to wear gloves when handling mercury. Torricelli’s Experiment The first person to measure the magnitude of air pressure is Italian scientist Torricelli. He was filled with mercury (Hg) in a glass tube with … more
This simulation supports both pinch zoom and mouse scrolling. We recommend using the Chrome browser. (to get more processing speed) Imaginary number An imaginary number consists of a number that becomes negative if you square itself. … more
