# Movements Simulation

## 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...

## 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...

## “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....

## 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...

## 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...

## 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...

## 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...

## F = ma (Newton’s law of motion)

Force changes the motion Consider the process of changing the movement by applying force to the cart. If the amount of force acting on the cart is doubled or tripled, the speed change is doubled or tripled. If the force...

## Parabolic motion (Monkey and Hunter)

Projectile Motion When you throw an object, the object falls with a certain curve. The object performs a parabolic motion. This is a motion on a two-dimensional plane, not a straight line. To understand this movement, it is necessary to...

## Conical pendulum

3 forces acting on a conical pendulum Gravity(=mg): The force the Earth pulls. Tension: The force applied to both ends of the thread. Tension is always directed to the center from both ends. Centripetal force(Fc): The force that maintains circular...

## Condition of Uniform Circular Motion

Even if the force works, the speed does not change? When an object moves linearly at a constant velocity, the force applied to the object is zero because there is no change in velocity. If so, is there a motion...

## Three Body Problem

* As the operation is repeated, the above simulation may expand the error due to the decimal operation’s limitation. * If your computer is outside of the limits that it can handle (overly large or small numbers), it may freeze....
