Animation & Explanation by BIGS
Currently no longer available as an animation, but accessible here as a YouTube video in English, free of charge. Click on the image to start the video.
As a free animation, however, it is available here as a downloadable executable file for Windows Tragheitsprinzip_Flugzeug.exe.zip
Please note that some Windows settings may block the download. However, under the „More Information“ button and then the „Run Anyway“ button, you can allow the download.
Explanations for the Animation „Principle of Inertia“
Without Air Resistance
The package, as part of the airplane, has exactly the same speed as the airplane. When it is dropped from the airplane, it retains this horizontally directed speed according to the principle of inertia, assuming air resistance is neglected. Simultaneously, the force of gravity creates a parabolic trajectory, with the endpoint at impact located directly beneath the moving airplane.
With Air Resistance
The package, as part of the airplane, has exactly the same speed as the airplane. When it is dropped, air friction (air resistance) gradually reduces the horizontal velocity component on its way down while also extending the time it takes to reach the ground. Compared to the case without friction, the resulting parabolic trajectory is compressed, and the impact point will no longer be directly beneath the moving airplane. Instead, it will lie more or less ahead of the plane, depending on wind conditions.
