User reviews

Cannot! figure it out

I can exert considerable effort, hunting down functions and after that effort…I have a rectangle. I can’t figure out how to connect it to any pivot, other block or background to create a solid pendulum.
In short, it’s full of promise, but takes a genius to use.
How about a walkthrough or two? Thx.

POWERFUL TOOL

Thank you so much for this developer.

As a vr game designer, who does not code..

and has to quickly test physics based ideas (object bouncing off a another object via collision) and so many other physics based idea tests.

I can tell this list have been created by one developer, with that said… I appreciate all effort and detail you placed into this gem 💎

This is a powerful tool for vr design ideas here in the 2D planescape.

Help

For me this app does nothing. I was using the Autodesk Force-Effect family of apps which much to their detriment they discontinued. With this app I have been unable to put together even a simple fulcrum. Where are tutorials or a useful help file? VERY disappointed

Very good app... I have a few requests!

I like is app very much! I'm using it in my University physics course. There is a lot you can do with it to enhance your teaching!

I have a request. It will be nice to have the diagrams (x vs t, etc) a little bit smaller. It will be helpful if I can show simultaneously the simulation and the diagram so the students can see the actual motion and the diagram. It will be GREAT if multiple diagrams can be shown at the same time (x vs t, Vx vs t, a vs t) while running the simulation.

This is a great app and it has the potential to be even greater!

Love it!

FAQ

What is Newtonium?

Newtonium is a physics simulator designed to help users understand and solve classical mechanics problems. It calculates forces and simulates object motion in two dimensions, allowing for detailed analysis and visualization.

What kind of physics problems can Newtonium solve?

Newtonium is capable of solving problems related to classical mechanics, including the motion of particles, objects interacting with forces like gravity and friction, and collisions. It can handle scenarios from small-scale particle movement to large-scale celestial body interactions.

Can I create my own physics scenarios in Newtonium?

Yes, you can create, load, and save your own models within Newtonium. You can define objects with specific physical properties, add tools like springs and pulleys, and set conditions for the simulation.

How does Newtonium display forces and motion?

Forces and velocities are displayed as arrows for each object during the simulation. The app also provides detailed descriptions of forces and can animate your model to help visualize motion and verify principles like conservation of energy or momentum.

What devices is Newtonium available on?

Newtonium is available for iPhone, iPad, and iPod devices. It is designed for Apple's mobile operating system.

How much does Newtonium cost?

Newtonium is a paid application and costs $0.99. This one-time purchase grants you access to all its features for solving physics problems.

Is Newtonium suitable for young children?

Newtonium has an age rating of 4+, suggesting it is suitable for a broad audience. However, its complexity in simulating physics concepts may be more beneficial for older students or adults interested in mechanics.

How often is Newtonium updated?

The latest version of Newtonium, 1.3.8, was released on April 13, 2020. While the app has not been updated recently, it remains a functional tool for its intended purpose.
