## Video-based Motion Analysis (Free software that replaces Tracker & Motion Shot)

X min X max Y min Y max This program analyzes the movement of objects captured on video frame by frame. It may not work on Apple devices or in-app browsers./li> You can upload and analyze the video you shot … more

## Movement of an object suspended from a pulley

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 gravity $$g$$ act in … more

## Free Fall Motion Analysis

Why do light and heavy objects fall at the same time? The change in speed due to gravity is the same for all objects because the force and inertia acting on an object are proportional to the object’s mass. The … more

Newton’s cradle Newton’s cradle consists of five iron balls, each hanging on two threads to prevent the ball from spinning. Originally Newton’s cradle was created to demonstrate Newton’s third law. If you collide a ball from one side, the exact … more

## Boyle’s Law 2

Drag the standard weight and place it on top of the piston. You can download graph data. Boyle’s Law Doubling the pressure of a gas reduces the volume of the gas by 1/2, and increasing the pressure of a gas … more

## Mechanical Energy Conversion 2

Mechanical energy As the roller coaster descends from a high place, the height decreases, and the speed increases, so the potential energy decreases, and the kinetic energy increases. Therefore, potential energy is converted into kinetic energy while the roller coaster … more

## Moment of Inertia

This simulation assumes that there is rolling friction and no sliding friction. The cylinder and cube assumed the density of iron (7.874 g/cm³). Why does a rolling object go down slower than an object that slides down? In conclusion, the … more

## The charging and discharging characteristics of capacitor。

Switch up to start charging, and switch down to start discharging. The measured voltage is recorded automatically when charging or discharging starts. You can change the measuring point by moving the probe. For accurate measurement, operate the switch after fully … more
