About

equivalence principle

Features
Read full description

This app represents the equivalence principle which states that gravitational and inertial forces are of a similar nature and often indistinguishable. Left rocket is moving up with constant acceleration a, and right rocket is on the some planet where the gravitational acceleration is g. If a is equal to g, the motion of a ball which is dropped in the left rocket is the same as the motion of a ball which is dropped in the right rocket; two balls experience the same constant acceleration motion. This is the simple demonstration of the equivalence principle. This app doesn't simulate the whole motion of a ball. Only falling motion is intended to show the equivalence principle.

About

Root Locus Plotter

Features
Read full description

Root Locus Plotter is an educational and engineering tool designed to help you visualize and analyze control systems through the Root Locus method. Whether you’re a student learning control theory or an engineer designing feedback systems, this app makes it easy to understand the dynamic behavior of transfer functions and how poles and zeros affect system stability. - Key Features Root Locus visualization: Instantly plot the root locus of any transfer function. Gain and stability analysis: Inspect how system poles move and identify stable or unstable regions. Step response: Visualize the step response with interactive charts and get the analytic expression for transient and steady-state behavior. Support for complex systems: Works with higher-order transfer functions. Compare before and after compensation: View the root locus and step response for both the original plant and the compensated system side by side. - Educational Use Ideal for students studying control systems, feedback theory, and dynamic response. The app provides a clear and intuitive way to connect mathematical analysis with visual intuition β€” a great aid for classroom learning, homework, and lab work. - Engineering Use Engineers and researchers can use Root Locus Plotter to quickly test transfer functions, prototype controller gains, and study how poles and zeros interact under varying parameters. - Get Started Simply enter your transfer function in a clean, intuitive interface, and explore how it behaves as system parameters change. Root Locus Plotter helps you make control theory visual, interactive, and understandable.
