Physics 101 contains over 75 equations and over a dozen simulations and tools covering the most important aspects of physics. Simulate a circuit, or launch a projectile, or work with the most common force diagram situations, and more. Whether you are a teacher wanting to augment your lessons or a student wanting better grasp of the material, Physics 101 is your go-to solution.

Physics is more than just a numerical answer — it is about understanding the rich nature behind the equations. Each formula explains its purpose and lists out an explanation for each of the variables used. Since Physics 101 lets you calculate values on the fly you can start to uncover the subtle and nuanced nature of the equations as you manipulate values in the formulas and simulations.

An amazing app for class

As a physics teacher who has been teaching for over a decade this app has everything you need for such an unbeatable price.

I can very quickly check student work that would otherwise slow me down. I also love projecting features such as the projectile simulator to make quick points with a class.

I do worry students can use this to zip through their work, but like anything, if they use it as a tool to understand then they'll be fine.

A must have for any students!

I cant say eneough about how useful this app is. I've been using it for a long time now and I recommend it to as many people as I can. If you are a highschool or college student who has to take any physics at all then you will really thank yourself for getting Physics 101. It has saved me more time than I can imagine.

Perfect for Physics

This app perfectly helps with both understanding the mathematical anc conceptual concepts of Physics! Anybody struggling in Physics will improve so much simply by using this app!

Definitely worth the price.
