## What is Motion Physics Gallery?

Motion Physics Gallery is a collection of interactive physics simulations. The app interface and learning explanations are in Japanese.

Change height, gravity, mass, speed, angle, wavelength, focal length or voltage, then tap GO. Run A and B together to observe how changing one condition affects the result while keeping the other conditions shared.

11 INTERACTIVE EXHIBITS
- Motion under gravity: falling, upward throws, horizontal and angled launches, and air resistance.
- Pendulum: length, gravity, amplitude and period.
- Collisions: mass, velocity and motion before and after a collision.
- Levers: the fulcrum, lever arms and balance of forces.
- Buoyancy: object and liquid density, floating and sinking.
- Wave superposition: two waves and their combined wave.
- Standing waves: string length, frequency, nodes and antinodes.
- Doppler effect: a moving sound source and changes in observed pitch.
- Reflection and refraction: angle of incidence, refractive index and total internal reflection.
- Lenses: converging and diverging lenses, focus, images and two-lens setups.
- Electric circuits: voltage, resistance, current and bulb brightness.

CHANGE, RUN AND COMPARE
- Compare A and B with one selected condition changed.
- Start synchronized animations with GO.
- Adjust sliders. Selected experiments also let you drag objects or controls directly in the experiment area.
- Observe motion using time-spaced images, vectors and scales.
- In Motion under Gravity, switch between 2D and a 3D view that you can rotate and zoom.
- In Doppler Effect, compare the source tone with the observed tone.
- Animated tutorials demonstrate how to use the experiments.

Each exhibit uses a simplified educational model, with its assumptions explained in the app. The models do not reproduce every real-world effect of friction, shape or the environment.

The experiments run on your device and can be used offline. No account registration or ads.
