Magnetic field around magnet The space where the magnetic force of the magnet acts is called a ‘magnetic field.’ The direction of the magnetic field is determined in the direction indicated by the N pole of … more
Pendulum wave A ‘Pendulum wave’ is a collective wave-like phenomenon that appears when pendulums (weights) of different lengths are arranged side by side. Because each pendulum has a different period depending on its length, they oscillate … more
Scientific definitions of ‘up’ and ‘down’ We live on the surface of the Earth and are always under the influence of its gravity. When we let go of an object, it falls “down,” and when we … more
This simulation analyzes the sound around you and displays it as a spectrum. The simulation works by recognizing the surrounding sounds. In the case of PC, please grant permission to use the microphone. Voice data is … more
Doppler Effect By listening to the ambulance’s siren, we can tell if the ambulance is coming or going. When an ambulance approaches with a siren, the sound wave’s wavelength becomes shorter (higher note), and when it … more
Direction of the Lorentz force Conductors in which current flows in a magnetic field are forced to move. The direction of this force is perpendicular to the current and the magnetic field, respectively. More precisely, we … more
Range X min X max Y min Y 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
Conduction The ‘conduction’ of heat is how heat is transferred by moving particles that make up an object to neighboring particles. Heat can be transferred even if the particles do not move, mainly by vibration or … more
Convection in the room There are three ways to transfer the heat: conduction, convection, and radiation. Convection is the method by which heat is transferred by the direct movement of particles that make up a liquid … more
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
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
