📏 Ruler Measurement Experiment

Learn about measurement accuracy and instrument precision

1. Setup
📌 Experiment Information: A random line with a specific length has been generated. You need to measure this line multiple times with a ruler.

📏 Actual Line Length: - cm

⚙️ Instrument Precision (Ruler): ±0.1 cm (enter only one decimal place)

🎯 Objective: Understand how reading precision from a ruler affects measurement accuracy.
2. Measurement
🖱️ Controls:
• Drag the ruler (horizontally and vertically) to position it over the line
• Align the line with the ruler's zero mark and read the endpoint
• Press [Z] key to enable zoom (magnifying glass)
• In zoom mode, move the mouse over the ruler to magnify that section
