Newton interprets 2D composition layers as rigid bodies interacting in a real environment. Newton provides many simulation controllers such as body properties (type, density, friction, bounciness, velocity, etc), global properties (gravity, solver), and allows the creation of joints between bodies. Once simulation is completed, animation is recreated in After Effects with standard keyframes.
