## Introduction

{% embed url="<https://www.youtube.com/watch?v=qdxouJvvyw0>" %}

Toolkit for Physics is a collection of physics-focused APIs, components and tools providing stable easy-to-use solutions to common physics simulation needs.

All Toolkit features are designed to be lightweight, and modular and work alongside Unity's built-in tools and features, not replace them.

### Key Features

[Verlet Spring](/old-kb/toolkit-for-physics/physkit/core-features/intorduction.md)

Add dynamic physics-based motion to transforms and armature bones

[Ballistics](/old-kb/toolkit-for-physics/physkit/core-features/ballistics-tools.md)

Solve, predict and ray-cast ballistic (parabolic) trajectory

[Force Effects](/old-kb/toolkit-for-physics/physkit/core-features/force-effect-framework.md)

Create spherical gravity, tractor beams, wind fields and more

## Feature Comparison

Toolkit for Unity Physics can be purchased as a complete collection on the Unity Asset Store and is available to GitHub and Patreon Sponsors.

The Ballistics and Verlet modules are also available on the Unity Asset Store as stand-alone assets.
