Newton 3 Review and verdict 2026

2D physics simulator for After Effects. Realistic collisions, gravity, springs.

Our take

Understanding Newton 3.

Newton is a 2D physics engine for After Effects. Instead of animating each bounce and collision by hand, you give your layers physical properties (gravity, mass, bounce, friction) and Newton computes realistic motion: objects falling, stacking, colliding, type tumbling down. For a motion designer, it enables organic animations that would take ages to keyframe.

It's a one-time purchase (aescripts/Motionboutique) around $250, no subscription. It's pricey for a plugin, but a lasting investment if you use it regularly.

Who it's for: motion designers who do physics-based animation. If your projects don't include any, Newton will be useless to you. But the moment you need realistic motion with interactions between objects, it has no real equivalent in After Effects.

Practical uses

Animate bouncing balls or objectsRealistic physics.
Create organic oscillations and vibrations on text or shapes.
Simulate floating chains or waving flags.
Natural falling or collision effect without manual keyframing.

Pros and cons

What Newton 3 does especially well — and the limits to anticipate.

Pros

Professional, flexible physics simulation.
Saves huge time on physics keyframing.
Results auto-converted to AE keyframes (editable after).
Perpetual license (no subscription).
6 object and joint types offer advanced control.

Cons

High price for specialized plugin.
No free version; only a student discount is available.
Newton 3 no longer updated (Newton 4 recommended, paid upgrade).
Learning curve: understanding physics and constraints.
May be overkill for simple animations.

Newton 3: when it makes sense.

Newton 3 pays off for frequent physics animations; for occasional use, After Effects built-in effects suffice.

Keep if

You create complex animations with realistic physics (bounces, oscillations).. You want to avoid manual keyframing for physical movement.

Challenge if

You're new to animation and want to master basics first.. You mostly do simple graphic motion design.

Our verdict on Newton 3.

Why this verdict

Decent

Newton 3 is hard to replace short-term, no free tier to test before paying, clearly documented use cases.
