Science Simulations
Coriolis effect The French mathematician Coriolis first explained that the direction of fluid movement on the Earth’s surface is slightly warped. You can observe this effect in all spinning places like Earth. The Coriolis effect causes … more
The sensing part is slightly different depending on the frequency of sound. Move the slide bar to check. Cochlear Inside our ears, there is a sensory organ that senses sound. The overall shape resembles a snail … more
You can drag the screen to rotate it. Temperate cyclone (also known as Extra-tropical cyclone) The temperate zone is where the north’s cold air mass meets the south’s warm air mass. When two different chunks of … more
The air conditioner The air conditioner is based on ‘evaporative heat'(a phenomenon that absorbs the surrounding heat when the liquid evaporates). The indoor unit suddenly expands the compressed refrigerant through a narrow hole. Then, the refrigerant … more
Altitude-temperature data is based on ISA(International Standard Atmosphere). Values other than the data were obtained using spline interpolation. Altitude(km) Air Temperature(℃) 0 15 4 -11 8 -37 12 -56.5 20 -56.5 30 -46.5 40 -22 50 … more
What is Covalent Bond? The covalent bond is a bond formed by atoms. Each atom creates an electron pair and shares it. Because each other’s electrons are shared in pairs, the number of electrons involved in … more
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 … 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 … 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 … 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
