Science Simulations
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
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 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
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
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
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
* 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
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
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
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
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
* Please refer to the text below for how to make a graph. Free fall motion If you hold the ball in your hand and release it, it will fall. In the absence of air resistance, … more
