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!
