Movements Simulation
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 would increase by 9.8 … 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 ‘1’. General relativity General … more
Three Body Problem
x y Vx Vx * 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. * As the operation is … 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
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 indicates the speed. A … 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 adjusting the drag speed. … 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 data never stored on … more
Analysis of Free Fall Motion
* 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, the only force acting … more
Average velocity and instantaneous velocity
Record of movements The motion of an object can be more easily understood by graphing it. In the time-distance graph, the slope is equal to the velocity. The average velocity that an object has moved over a certain period of … more
Ticker Timer (Movement on the slope)
Ticker Timer It is a device to record an object’s movement by taking a spot on a paper tape at regular time intervals. A typical ticker timer is plugged into a household outlet. So the ticker cycle of the ticker … more
