Flowy14 vs equivalence principle

Flowy is a Flowcharting Programming Environment. It is an interpreter. It allows users to see how their programs execute, which helps form a greater understanding of software development. Flowy comes with prebuilt demos and a simple tutorial, executing those will demonstrate app's capabilities. User's imagination and creativity will take it further. Using Flowy, programmer assembles building blocks, connects data flow between them and executes the program. Flowy then visually executes blocks in logical sequence and animates results at run-time.

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.
