Inside the film
What it shows
Twice as fast means four times the energy. The film draws it on a photo of a swing: kinetic energy is greatest at the bottom, where the swing moves fastest, and because the energy grows with the square of the speed, doubling the speed quadruples it. Read the page five times, or ask it to show you.
The DuckyHelper part
In this film, it sees what is on the screen and draws on it. That is DuckyHelper on any screen: press one key in any app and ask.
- Press fn on a Mac, or Ctrl+Shift+Space on Windows and Linux, in any app.
- Ask your question out loud, the way you would ask a person next to you.
- Watch it explain on your screen or on the blackboard, then answer its question back.
