## What is Newtonium?

Newtonium is a powerful tool to solve physics problems. For those of you, who are having difficulties understanding and solving classical mechanics problems, this app is a huge help.It will calculate all forces exerted on a body and simulate the resulting motion in two dimensions, with three degrees of freedom.

Use objects, structures and tools to build your model. You can set physical properties, like mass, velocity, size, position and many more. The app will calculate and show you all the forces on each object. To see the forces in action, just run the simulation. Even during the simulation all forces can be shown and all properties will be updated. You can specify final conditions, to stop the simulation automatically, when these conditions are met.

From the very small like the motion of particles to the very big like the moon going around the earth, if you can draw the model, Newtonium can calculate the forces.

Features:
- create, load and save your models
- change gravitation, friction, resistance or behavior during collisions
- specify real world physical properties of all objects
- use tools like springs, struts, and pulleys
- units are converted automatically
- set initial and final conditions
- forces and velocities are displayed as arrows for each object
- forces are described in detail
- use the simulator to animate your model
- display diagrams for objects in motion
- verify conservation of energy or momentum

## Key features

- Build and simulate 2D physics models
- Set physical properties for objects
- Visualize forces and velocities
- Adjust gravity, friction, and resistance
- Specify initial and final conditions
- Animate models and display diagrams

### 2/5 — Cannot! figure it out

*2026-02-23*

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.

### 5/5 — POWERFUL TOOL

*2023-02-23*

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.

### 1/5 — Help

*2018-08-10*

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

### 4/5 — Very good app... I have a few requests!

*2017-02-10*

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!

### 5/5 — Useful and fun

*2017-01-12*

I can make any experiment in physics using this app. this activity is not only informative, but also very fun

### 5/5 — Helpful in solving classical mechanics problems

*2017-01-10*

What I love the most about this app is its accuracy. Even complicated tasks are solved fast and I can be sure that data is precise

### 4/5 — It is the better tool!

*2017-01-09*

Very useful app. I think this app can solve different physics problem. If you study physic in University or school, this app can be very important and helpful for you.

### 5/5 — Worth trying

*2017-01-09*

Amazing app. Helpful for those who are interested in solving mechanics problems

### 4/5 — 👍🏻

*2017-01-06*

Thanks for providing such a good app for free

## Frequently asked questions about Newtonium

### 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.
