## 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 a pulling force on … more

## Solar System

Solar System All the orb bodies that revolve around the sun and their space are called the solar system. The celestial bodies that make up the solar system include the eight planets revolving around the sun and the sun, the … more

## 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 … more

## Galilean Moons

* This simulation refered the link below for Jupiter’s satellite data. https://en.wikipedia.org/wiki/Galilean_satellite Galilean satellite Jupiter, the largest planet in the solar system, has many moons. Jupiter’s representative moons include Io, Europa, Ganymede, and Calisto. These four satellites are called Galileo … more

## Principle of Satellite

How cannonball become an artificial satellite? a. Imagine that a cannonball falls in a parabolic curve. The trajectory the cannonball draws is actually part of an elliptical orbit centered around the Earth. The center of the Earth corresponds to the … more

## Path of Satellite

From the perspective of an observer on Earth, the orbits of satellites with an orbiting period of less than 24 hours appear to move westward little by little with each turn. This phenomenon occurs because of the Earth’s rotation.
