Polygonal Wheel
Polygon Wheel Should the wheels always be round? All polygon wheels can roll smoothly. To do this, you need a suitable floor. How is the floor for the polygonal wheel to roll smoothly? The floor shown in the above simulation … more
CMYK Color Division by File Drop
When you upload an image file, the simulation divides the image into four primary colors (Cyan, Magenta, Yellow, Black) of the pigment. You can see the original colors by printing on transparent transparencies and then overlaying them. Please turn on … more
CMY Color Division by File Drop
When you upload an image file, the simulation divides the image into three primary colors (Cyan, Magenta, Yellow) of the pigment. You can see the original colors by printing on transparent transparencies and then overlaying them. three primary colors of … more
Particle Simulation of Thermal Conduction
About this simulation This simulation shows the particle’s temperature by its color.● Red means high temperature.● Blue means low temperature. We apply Hooke’s law between particles.(\(f=-kx\)) Thermal Conduction Conduction is a method of transfer of heat that occurs primarily in … more
Conduction
Conduction of Heat If a high-temperature object and a low-temperature object are attached to each other, the high-temperature object’s heat moves to the low heat by molecular motion. Examples of Conduction that can be seen around us Gold, silver, iron, … more
Microphone and Speaker
The simulation works by recognizing the surrounding sounds. Please turn off the silent mode on your mobile device for microphone detection. In the case of PC, please grant permission to use the microphone. Voice data is not stored on servers, … more
Three Primary Colors
* Touch the screen to move the colored circles. Three primary colors of light Red, green, and blue are called the three primary colors of light. You can create any color by adjusting the light of these three colors appropriately. … more
Root-Mean-Square Velocity of Gas Molecules (Vrms)
* The gas molecules in the above simulation are all of the same type, and the color of the molecules is for identification purposes only. Kinetic Molecular Theory of Gases ‘Kinetic Theory of Gases’ is a hypothesis to explain the … more
Rainbow by Raindrops
A rainbow is a natural phenomenon where the dispersion of light is most visible. As you know, We can see a rainbow after rain because the water droplets bend and disperse the light. For example, if we spray water on … more
Seismic Wave
Investigation inside the Earth The surest way to see what the Earth is like is to penetrate and see it yourself. However, there is a limit to penetration because the temperature and pressure rise as you enter the Earth. Therefore, … more
Real Size & Orbit of Earth and Moon
The photographs of the Earth and the moon close together that you can see on posters, etc., are designed to be easy to see. The moon’s apparent diameter is only about 0.5˚. This tells us that the Earth and the … more
