Just imagine you want to find out which forces have an impact on a bungee jumper. Or whether the amount of fun you have on a roller coaster differs depending on sitting in the first or the last car. Maybe you want to get to the bottom of the moon landing in 1969. Did it really take place or are the videos just fakes produced in a film studio somewhere on our planet as alleged by several obscure sources? These and other questions about kinematics can be answered easily with NewtonDV. The app analyses the movement of persons or objects in a video using mere physics. All you need is a given film sequence — or record your own video with NewtonDV. Range of functions: - Recording HD and slow-motion videos using the built-in iPad camera (up to 240 fps) - Importing videos from the photo library, Files app, iCloud Drive, or via AirDrop - Rotatable coordinate system for inclined planes or rotated recordings - Displaying measurement data in tables and diagrams - Drawing trend curves - Creating time strips and stroboscopic images - Displaying velocity and acceleration vectors with numerical values - Exporting tables and diagrams as png files - Exporting measurement data as csv files for further analysis in a spreadsheet program - Sharing tables and diagrams via email - Printing tables and diagrams - Light and dark mode

Welcher Stern gehört zu welchem Sternbild ? Haben Sie sich das auch schon einmal gefragt oder sind sogar Hobbyastronom? Dann ist diese App für Sie sehr hilfreich dieses zu erlernen ,im Himmel zu erkennen .Es bringt Spaß sich spielerisch durch ein Sternen und Sternbilder- Quiz durch zu klicken und sein Wissen zu überprüfen. Dabei werden Nord-und Südhimmel berücksichtigt. Die Sternensuchfunktion hilft dabei das Teleskop schneller einzustellen ,da gerade am Anfang das Alignment Schwierigkeiten bringen könnte. Es hilft auch dabei: - Sterne einem Sternbild zuzuordnen - deren Position über eine Karte zu bestimmen - zu erkennen welche Sterne auf dem Feld nicht von Bäumen oder Gegenständen verdeckt sind, um dies dem Teleskop mitzuteilen - festzustellen ob das Alignment(Ausrichten) vom Teleskop richtig arbeitet - das Teleskop sicherer per Star hopping über den Himmel zu bewegen. Die App ist auch Offline erreichbar, damit man auf dem Feld nicht abhängig vom Internet ist.
