You can view the solar system simulation at this website:
This is a solar system simulation I programmed for an 8th grade science class project. Using the gravitational force equation and Newton's second law, it calculates where Mercury, Venus, Earth, and Mars will go. While forces on all individual planets can be calculated by this simulation, I only displayed Earth's information to save space.
Through this project, I learned Newton's three laws of physics and kinematics. Prior to completing this project I had not yet taken a physics class, so learning these skills was valuable as I later went on to work in robotics and study physics formally.
