Alternatives. What could replace Newton 3?
No established substitute
No tool in the catalogue covers the same need as Newton 3. Rather than suggest an approximate match, here is the neighbourhood view.
Newton 3 (and successor Newton 4) is a 2D physics simulation engine for After Effects that makes layers behave like solid objects with gravity, collisions, friction, and springs. Applies realistic forces (bounces, oscillations) to text, shapes, and elements without manual keyframing.
