Physics
How to use?
Tools that simulate physical phenomena: adjust the parameters and watch the system respond in real time, with integrated animations and charts.
Who is it for?
Students of physics, engineering, and related fields who want to understand phenomena beyond solving equations.
How to use them?
Select a tool, adjust the values using the available controls, and explore the system's response. The Fundamentals section explains the physics and equations behind each simulation.
