Newton is an awesome plugin for After Effects that simulates 2D physics. As someone who has worked with 3D programs such as Cinema 4D where simulating physics is very smoothly built in and advance, this plugin is a great crossover. Instead of key-framing a ball bouncing for example and trying to make it look as real as possible, Newton allows you to tweak real world physics properties of your objects and simulate real physics. It is great for having things that react to gravity such as objects falling. You can set objects as static and all objects will collide with each other automatically, which is very handy. The plugin has tons of possibilities, which I look forward to exploring, and I have been using some on my third project.
The program is $250 but you can get a free trial and try it for yourself. Here is the website, and here is where you can download it. I highly recommend you check it out.
