Is this an AI image generator?

No. This is a deterministic physics diagram tool. It calculates positions and velocities from your inputs, then renders the diagram as SVG in the browser.

Does the tool use credits?

No. The tool does not call an image model or LLM. It runs locally in the browser and does not use image-generation credits.

How are the dots placed?

Dots are placed at equal time intervals using x(t) = x0 + v0t + 1/2 at^2. Equal spacing means constant speed, increasing spacing means speeding up, and decreasing spacing means slowing down.

How are velocity arrows drawn?

Velocity arrows use v(t) = v0 + at. The arrow direction follows the sign of velocity, and the arrow length is scaled relative to the largest velocity in the current diagram.

Can I download the diagram?

Yes. You can download the current motion diagram as SVG or PNG, and export the calculated motion table as CSV.

Should I use this instead of the Free Body Diagram Generator?

Use this page for position, velocity, acceleration, and dot diagrams. Use the Free Body Diagram Generator when you need force arrows such as weight, normal force, friction, tension, or applied force.

Motion Diagram Examples

Compare six common classroom cases: constant speed, acceleration, deceleration, leftward motion, vertical throw, and free fall.

Constant Speed

v₀ = 2 m/s, a = 0 m/s²

Speeding Up

v₀ = 0.8 m/s, a = 0.7 m/s²

Slowing Down

v₀ = 4 m/s, a = -0.55 m/s²

Thrown Upward

v₀ = 4.8 m/s, a = -1.2 m/s²

Moving Left

v₀ = -2 m/s, a = 0 m/s²

Dropped Object

v₀ = 0 m/s, a = -1.4 m/s²

What is a motion diagram physics maker?

A motion diagram physics maker builds a visual model of an object at equal time intervals. Each dot marks position at one snapshot in time. Dot spacing shows relative speed, velocity arrows show direction and speed, and the acceleration arrow shows how velocity changes.

Why this tool uses precise SVG rendering

Motion diagrams are physics models, so dot spacing and arrow direction should follow the motion values exactly.
The tool calculates position with x(t) = x0 + v0t + 1/2 at^2 and velocity with v(t) = v0 + at.
It renders a clean SVG in the browser instead of using an AI image model, so the same inputs always produce the same diagram.
SVG, PNG, and CSV export make the result useful for worksheets, slides, homework explanations, and lab notes.

What can you adjust?

Initial position, initial velocity, acceleration, time interval, and number of dots.
Presets for constant speed, speeding up, slowing down, moving left, and vertical throw examples.
Velocity arrows, acceleration arrow, and time labels can be shown or hidden.
CSV export includes every time, position, velocity, and acceleration value.

Motion diagram vs free body diagram

A motion diagram describes kinematics: where the object is, which way it moves, and whether velocity changes. A free body diagram describes dynamics: the forces acting on the object. They are connected, but they are not the same diagram.

When to use this tool

Explaining constant speed, speeding up, and slowing down motion.
Building classroom worksheets about position dots, velocity arrows, and acceleration direction.
Checking whether a written motion description matches a diagram.
Creating clean physics visuals without spending image-generation credits.
