## What is Physics!?

Physics! is a physics calculator which allows you to find:

- Force, Mass and Acceleration

- Momentum, Mass and Velocity of a moving object

- Period and Frequency of a Pendulum

- Distance, Time and Gravity

- Pressure, Area and Force

- Potential Energy

- Kinetic Energy

- Velocity, Wavelength and Frequency for Waves 

The app uses SI units.

There is a pro version of the app which allows you to calculate everything in this version, as well as:

 - Universal Gravitation
 - Work, Force and Distance
 - Power, Work and Time
 - Rotational Inertia
 - And more.
 - Plus, you can create your own formulas with an intuitive interface.

The Pro version allows you to easily select different units for your calculations.

Also, check out Geometry! for all your geometry formula calculations.

## Key features

- Calculate force, mass, and acceleration
- Determine momentum and velocity
- Compute pendulum period and frequency
- Calculate distance, time, and gravity
- Find pressure, area, and force
- Calculate potential and kinetic energy
- Solve for wave velocity, wavelength, and frequency

### 5/5 — love it

*2019-10-16, version 3.1*

Love it😝😝😝😝

### 1/5 — Another paid app

*2016-08-22, version 3.0*

Another app you have to pay for in order to have personal custom

### 3/5 — Not a bad app

*2014-12-14, version 2.5.1*

Did what I needed it to do.

### 2/5 — I recommend Physics X

*2014-10-15, version 2.5.1*

If you are looking for quality content, I recommend the app Physics X, also on the app store

### 3/5 — Waves, graphing, theory

*2014-08-29, version 2.5.1*

needs
-amplitude
-temperature

needs
-3D graphing to measure spheres against cubes; and the like

needs
-principles in detail by name
-analysis of pi concept
-general relativety
-quantum mechanics
- dimensional analysis

If the full version had any of these additional measurements or theories it would be more worth purchasing

### 1/5 — Worst

*2014-04-11, version 2.5.1*

Equations aren't correct and f=ma is Newton's second law

### 1/5 — Um?

*2013-09-28, version 2.5.1*

Calculator for these equations isn't necessary. I thought it would've been a little more complex equations. Animations or plotting would be nice. Also, f=ma is newtons second law, not newtons first law, and this is only when mass is constant.

### 4/5 — Could use more equations

*2013-07-10, version 2.5.1*

Not sure if the pro version offers more equations, but this version a couple more advanced equations. Also I gave you my email but the ads still exist

### 1/5 — Silly

*2013-03-02, version 2.4.2*

This app is worthless. If you need an app to calculate F=ma then you need way more help than this app could provide (like a brain or a clue). That there's a "pro" version that lets you use English units is comical. Apps like this signal the coming of the apocalypse.

### 1/5 — Well, if algebra is physics I suppose this is OK'D

*2013-02-03, version 2.4*

More of a demonstration of how to write an app than an application per se.  Perhaps they should include a spelling checker so that "pendulum" could be spelled correctly.
