No rulers. No protractors. No guessing.
Stop sketching force arrows by hand. Describe your physics scenario in plain English and the AI draws a labeled free body diagram — vectors, angles, and components included.
Describe Your Physics Scenario
Write what's happening: a block on a ramp, a pulley system, a beam under load. Include details like angles, surfaces, and connections. The AI reads the physics, not just keywords.
AI Draws the Force Diagram
Within 30 seconds, the AI identifies all forces — gravity, normal, friction, tension, applied — and draws them as properly directed vectors with labels. No manual placement needed.

One Tool for Every Physics Problem
Students · Engineers · Instructors
Whether you're solving homework at midnight or preparing lecture slides for Monday, this free body diagram maker handles the drawing so you can focus on the physics.
Students
AP Physics to graduate mechanics
You understand the forces — you just can't draw them neatly. Describe your problem and get a labeled free body diagram you can include in homework, lab reports, or exam prep notes.
- Handles inclined planes, pulleys, circular motion, and more
- Labeled vectors with proper direction and notation
- Free credits on sign-up — no payment needed
Engineers
Statics, dynamics, and structural analysis
Generate clear force diagrams for beams, trusses, and mechanical systems. Export as SVG to annotate in your CAD workflow or include directly in technical reports.
- Supports beam reactions, distributed loads, and moment diagrams
- SVG export for integration with engineering documentation
- Consistent style across multiple figures in the same report
Instructors
Teach forces, not drawing tools
Create custom free body diagrams that match your lecture scenarios — not generic textbook images. Generate a new diagram for each class in under a minute.
- Match the diagram to your problem set — not the other way around
- High-contrast output readable on projectors and printed worksheets
- Generate variations of the same scenario for quizzes and exams

What Makes This Free Body Diagram Maker Different
Not a Generic Drawing Tool
Most diagram tools give you shapes and arrows to drag around. This one reads your physics scenario and draws the forces for you.
Identifies All Acting Forces
Gravity, Normal, Friction, Tension, Applied
Describe a block on a ramp and the AI draws gravity straight down, normal force perpendicular to the surface, and friction opposing motion — each as a labeled vector with correct direction.

How Students and Teachers Use It
Feedback from physics students, engineering majors, and instructors who stopped drawing force diagrams by hand.
Marcus Thompson
AP Physics Student, Thomas Jefferson High SchoolI used to spend 10 minutes drawing one free body diagram for homework. Now I describe the problem and get a clean labeled diagram in seconds. My physics grade went up a full letter.
Dr. Elena Vasquez
Physics Lecturer, University of Texas at AustinI generate custom free body diagrams for each lecture instead of reusing the same textbook images. Students engage more when the diagram matches exactly what we're discussing.
James Chen
Mechanical Engineering Junior, Georgia TechFor statics homework, I need 10-15 free body diagrams per problem set. This tool cut my diagram-drawing time from an hour to five minutes. I can focus on solving instead of sketching.
