What it does and how to use it

A skill that teaches Claude Code to do scientific tasks well. It is packaged knowledge the model uses whenever it is relevant.

Install the skill (command above).
In Claude Code, describe what you need - the skill turns on by itself when the context fits.
No commands to memorize: you talk in plain language and the skill does the rest.

Install (Claude Code)

mkdir -p .claude/skills/physics-mechanics && curl -fsSL https://doutorai.pt/data/lib/skills__physics-mechanics.md -o .claude/skills/physics-mechanics/SKILL.md

Paste this command into the terminal, in your project folder, and the component installs automatically.

# SymPy Physics and Mechanics

This document covers SymPy's physics modules including classical mechanics, quantum mechanics, vector analysis, units, optics, continuum mechanics, and control systems.

## Vector Analysis

### Creating Reference Frames and Vectors

```python
from sympy.physics.vector import ReferenceFrame, dynamicsymbols

# Create reference frames
N = ReferenceFrame('N')  # Inertial frame
B = ReferenceFrame('B')  # Body frame

# Create vectors
v = 3*N.x + 4*N.y + 5*N.z

# Time-varying quantities
t = dynamicsymbols._t
x = dynamicsymbols('x')  # Function of time
v = x.diff(t) * N.
