<h1>Rigidbody #1: Linear Forces</h1>
<section>
<p>
In this first installment of my 2D rigidbody tutorial, we are going to explore linear forces and how we can begin to simulate them in real time on a computer. As you'll come to see, 2D forces are quite easy to understand and implement if you have some basic knowledge of 2D maths. On top of that, they really add a lot of life into what would otherwise be a static 2D scene. Without further ado, let's jump in.
