Science Simulations
Movement on the pulley Two objects are connected by a string on a fixed, frictionless pulley and are moving together. In this case, the mass of the string and pulley is ignored. Since tension \(T\) and … more
Waves in spring When the left end of the spring vibrates, the vibration is transmitted to the other end. A spring can vibrate horizontally or vertically. Fixed-end reflection When a wave reflects off a fixed-end, the … more
About this app… This app can measure the length of a specific pattern that appears in an image (e.g., double slit pattern). You can upload and analyze images you have taken yourself. An object that can … more
What is the main frequency of the sound around us? Please allow the simulation to request microphone access. If you have set up the microphone or refreshed the webpage screen, touch anywhere on the screen once. … more
Range X min X max Y min V max This app is a web-based software that analyzes the motion of objects recorded in video frame by frame. This program analyzes the movement of objects captured on … more
Charging and discharging of capacitors A capacitor is a component that stores electrical energy in the form of an electric field. Assemble the capacitor and resistor on the breadboard, as shown below. When you press the … more
Kinetic theory model Gas particles are constantly moving in all directions. However, we cannot observe these gases because they are very small. The “Kinetic theory model” can replace these invisible gas particles with beads and make … more
This simulation shows the surrounding sounds as waveforms. Please turn off the silent mode on your mobile device to allow microphone detection. For PC, please allow permission to use the microphone. No voice data is stored … more
You can measure the voltages between 0 and 3.3V with micro:bit. Connect a 4.5V battery or USB power source to the micro:bit (3V batteries cannot be used). Do not measure excessively high voltages. It can damage … more
Color and Eye Recognition Visible light has various colors. Light has a different color depending on the wavelength (or frequency). So, how do people perceive color? Cone cells in the eye’s retina recognize color. There are … more
Boiling point and properties of substances All water boils at 100°C when heated, even if it has a different mass. In this way, the same kind of substance has the same boiling point regardless of quantity. … more
Magnetism of matter Materials can be divided into three types: ferromagnetic, paramagnetic, and diamagnetic, depending on how they react to an external magnetic field. Ferromagnetic In ferromagnetic materials, each atom acts like a magnet. In ferromagnetic … more
