CloudLabs Vectors vs equivalence principle

In this free practice the users will find squares and a Cartesian plane where they can freely draw one or more vectors, in addition to performing operations such as addition and subtraction of vectors, through the graphical methods of parallelogram and head-tail.

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.
