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
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
What is the difference between a magnet and an electromagnet? Let’s assume there is a small container you can’t see inside. There is a magnetic field around this container that can attract iron. Then, can you … more
Magnetic Force The magnetic force acts between two magnetic objects. Gravity only pulls, but magnetic force also has the force to push, including pulling force. When the different poles of the magnet are close, they pull … more
Vacuum Jar A vacuum jar(or vacuum sealer, vacuum container) is a container that can remove air using a pump. Originally, vacuum jars were made as kitchen utensils to help meat soak in seasoning. Now, they are … more
This simulation allows you to measure speed as a function of fall height. You can measure the speed at two locations and change the ruler’s orientation. Free fall movement All objects on Earth are affected by … 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
This simulation … Applied a geocentric coordinate system. Air friction is ignored. Covers fall and orbital motion due to Earth’s gravity. (However, the same can be applied to other celestial bodies.) Gravity Objects with mass exert … more
The fluid in the beaker is water, and its density is assumed to be 1 g/mL. The volume of the object is assumed to be 100 mL. Buoyancy When we wear a life jacket, our bodies … more
It is an optical experiment simulator consisting of a slit laser, lenses, and mirrors of various shapes. You can experiment by dragging the tool you want. Slit lasers are rotatable. Try dragging the red icon behind … more
This simulation allows you to measure speed as a function of fall height. Free fall movement All objects on Earth are affected by gravity. If there were no friction with air, the speed of any object … more
Doppler effect Electromagnetic waves (or sound waves) come into contact with another object while traveling; part of the wave is absorbed or reflected. A moving ball likewise absorbs or reflects some of the incoming waves. If … more
