Solar system making
Movement of the planets of the solar system The planets in the solar system receive gravity from the Sun and revolve around it due to this gravity. The following is a table of the orbital radius … more
Movements Simulation
Video motion analysis (Multi-flash photography, Stroboscope)
This app is Web-based software that converts video footage of an object’s motion into multi-flash photography. This program analyzes the movement of objects captured on video frame by frame. It may not work on Apple devices … more
Video Motion Analysis (Screen Pointing)
Range X min X max Y min V 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
Webcam Movement Analysis (on the table)
Try pushing an imaginary ball placed on the table with your finger. If your PC doesn’t have a camera, it won’t work. When the web browser asks for access to the camera, please allow it. (Personal … 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 … more
Gravity Simulator
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
Free Fall Experiment
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
General Relativity of Gravity
* After setting the small object’s mass, position, initial velocity, and initial direction of movement, turn on the ‘Run’ checkbox to start the simulation. * The gravitational constant of the celestial body were assumed to be … more
Three Body Problem
x y Vx Vy * The mass and gravitational constant of the celestial body were each assumed to be ‘1’. * You can edit the position and speed of each celestial body while not running. * … 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 … more
Graph of Constant Velocity Motion
The distance covered by an object moving at a constant speed increases proportionally with time. If the distance is plotted against time on a graph, it will result in a straight line with a slope that … more
“Free falling” or “Thrown to the horizontal direction”
How to use the simulation Drag the ball with your mouse to free fall it in the air. Drag your mouse on the cliff to observe the parabolic motion. You can change the horizontal speed by … more
