Describe your setup on the left to generate your own free body diagram
Stop sketching force arrows by hand. Describe your physics scenario in plain English and the AI draws a labeled free body diagram β vectors, angles, and components included.
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.
Within 30 seconds, the AI identifies all forces β gravity, normal, friction, tension, applied β and draws them as properly directed vectors with labels. No manual placement needed.
Export as high-resolution PNG for homework, lab reports, or presentations. Paid plans include SVG vector export for editing in Figma or Illustrator.
Students Β· Engineers Β· 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.
AP Physics to graduate mechanics
You understand the forces β 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.
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.
Teach forces, not drawing tools
Create custom free body diagrams that match your lecture scenarios β not generic textbook images. Generate a new diagram for each class in under a minute.
Real physics scenarios
Every diagram below was generated from a text description. Click any example to load the prompt and try it yourself.
Weight, normal force, and kinetic friction on a 30Β° ramp
Two masses with weight and tension over a pulley
Tension forces in two cables at different angles
Apparent weight during acceleration
Weight, normal force, and friction on a banked road
Point load with reaction forces at supports
Most diagram tools give you shapes and arrows to drag around. This one reads your physics scenario and draws the forces for you.
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 β each as a labeled vector with correct direction.

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 TechFAQ
Describe any physics scenario. Get a labeled force diagram in 30 seconds. No credit card, no drawing skills, no commitment.
Correct Angles, Components, and Labels
Force vectors point in the physically correct direction. Weight always points down. Normal force is perpendicular to the contact surface. Friction opposes relative motion. No guessing required.
Inclined Planes, Pulleys, Beams, Circular Motion
From AP Physics homework to university statics: inclined planes, Atwood machines, banked curves, hanging objects, and beam loading. Describe the setup and the AI handles the rest.
Faster Than Drawing by Hand
Type a sentence about your physics problem. Click generate. Your labeled free body diagram is ready before you could have found a ruler and protractor.
If You Can Describe It, You Can Diagram It
You don't need drawing software. Write 'box on a 30-degree ramp with friction' and get a clean, labeled free body diagram ready for submission.
PNG for Homework, SVG for Editing
Download 4K PNG for homework, lab reports, and presentations. Export SVG to adjust labels, colors, or layout in Figma or Illustrator. All exports are 300 DPI print-ready.
For 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.

Sarah Lindqvist
PhD Candidate in Biomechanics, KTH StockholmI needed force diagrams of joint loading for my dissertation figures. The SVG export let me match our lab's publication style in Illustrator. Saved me a full day of redrawing.
Prof. Robert Nakamura
Civil Engineering Faculty, UC San DiegoI use it to generate beam free body diagrams with different loading conditions for each exam version. Takes 30 seconds per variation instead of redrawing in PowerPoint.
Aisha Patel
Undergraduate, Imperial College LondonMy hand-drawn free body diagrams always looked messy and got marked down. The AI-generated ones are clear, labeled, and my tutor actually complimented the quality.
