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 … more

Spring pendulum(horizontal)
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
Spring Pendulum(Vertical)
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
Gravity Train
Like this simulation, if you drill a hole in the earth and throw it in, you can send it to the other side of the earth. This simulation ignores the effects of friction. The earth is … more
Standing Waves in various situations
A standing wave occurs when incoming and reflected waves interfere with each other. It produces a wave pattern that appears to be stationary. Nodes are locations where particles of the medium appear to be at rest. … more
