If Sir Isaac Newton could write an app, this is what he would create. Satisfy your demand for physics with this easy-to-use app, which is designed to simulate Newton's Universal Law of Gravitation and his three laws of motion. Enjoy hours of limitless physics at your fingertips.
>>Check out the built-in help section for a tutorial on how to use the app.
>>Note: this app uses fluent design elements, which are demanding on low-end hardware. If you experience lag, you are advised to go to Settings>Personalization>Colors and disable "transparency effects" under the heading "more options". After you change this setting, you may need to restart Fast Particle Engine.
>>This app works well with dark mode enabled. To switch to dark mode head to Settings>Personalization>Colors and click "dark" under "choose your default app mode".


History:
I was looking for apps for the TI-Nspire CX calculator, and I found some demo apps in assembly. The calculator warned me the app may not be compatible with the OS I had installed. I ignored the message, but the screen flickered and the particles became vertical lines: the app was unusable. I was not going to let an incompatible app stop me from enjoying particles, so I started working on what is now called Fast Particle Engine. It was a great learning experience for me. Now, 3 months later, I have uploaded it to the store so everyone can enjoy the particles from their favorite device.

Thank you for downloading!
