# Mechanics Simulation

## Spring pendulum(horizontal)

This simulation ignored the effects of friction. Simple harmonic oscillation In everyday life, we see a lot of the movements that repeated same oscillation. Like below, shaky or suspended objects are doing…

## Spring scales

Spring scales The spring scale is a tool that measures the mass and gravity of an object using the spring’s elastic force. Gravity is proportional to the mass of the object, and…

## Force to move the pendulum

Tension by gravity In physics, tension is the force on a string connecting two objects. Generally, the tension is calculated from both ends toward the center.길이 $$l$$인 진자를 Let’s consider…

## “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…

## Period of Physical Pendulum

A pendulum that vibrates can be classified as ‘simple pendulum’ and ‘physical pendulum’. A simple pendulum is a case in which the angular motion of an object can be ignored, such as…

## Spring Pendulum(Vertical)

This simulation ignored the effects of friction. Simple harmonic oscillation In everyday life, we see a lot of the movements that repeated same oscillation. Like below, shaky or suspended objects are doing…

## Force on Inclined Plane

Gravity acts on all objects. Suppose an object is placed on an inclined plane. This object is subjected to a force that slips downward by gravity. If the slope is θ, then…

## Gravity Train

Like this simulation, if you drill a hole in the earth and throw it in, you can send it to the other side of the earth. This simulation ignores the effects of…

## 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…

## Moment of Inertia

This simulation assumes that there is rolling friction and no sliding friction. Why does a rolling object go down slower than an object that slides down? In conclusion, the rolling object wasted…

## Little Prince’s Trampoline

All the forces of the universe act as ‘pairs’. How can a squid move that without fins? People may think of rockets through squid. Squid moves by squirting water out of the…

## 3 Body Problem

* As the operation is repeated, the error may be expanded due to the limitation of the decimal operation. * If your computer is outside of the limits that it can handle…
