# [Springs Physics](https://antosser.github.io/springs/?100&1)

Springs is an  html web application to simulate physics objects.

Every dot is connected to every other dot with a spring. Every spring wants to get to it's initial length.

## Controls

### Mouse

- **Left Mouse Click** - create dot at mouse position

- **Right Mouse Click** - create static dot at mouse position

### Quick Objects

- **Q** - create **sqare**

- **W** - create a **10-sided regular polygon**

- **E** - create a **25-sided regular polygon**

- **R** - create a **50-sided regular polygon**

- **T** - create a **100-sided regular polygon**

- **Y** - create a **250-sided regular polygon**

**Warning!** Do **NOT** spawn in two objects at the same place. This will cause a division by zero = **crash**

### Options

- **D** - Toggle showing the **dots**. **On** by default

- **F** - Toggle  **filling** the object. **Off** by default

- **G** - Toggle **following** the object. **Off** by default

- **L** - Toggle drawing the **springs**. **On** by default. Note: Recomended toggeling off for huge objects as it slows down everything heavily

### Arrows

- **Arrow Up** - Create a **force up** for each object

- **Arrow Down** - Create a **force down** for each object

- **Arrow Left** - Create a **force left** for each object

- **Arrow Right** - Create a **force right** for each object

### GUI

You can change the spring strength or timescale using the scalers on the page or using the url and reloading

### Start the simulation

You can press **Space** to start the simulation
