equivalence principle
Read full descriptionHide 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.

Verdict
The clearest difference is in-app purchases: equivalence principle at none against Konv's 1. Konv's advantage is iOS requirement (14.0 vs 16.0). On price, ads and device support there is nothing between them.
