\n
• F is the applied force (often the weight in Newtons),
\n
• x is the extension of the spring,
\n
• k is the spring constant (a property of the spring).

Key Components of a Hooke's Law Apparatus Weight Bars:

\n
1. Weight Hanger: \n
   \n
   • A bar or rod designed to hold weights securely.
   \n
   • Often made of metal, lightweight, with hooks or clips to attach to the spring.
   \n
   • It typically weighs a small, known amount (e.g., 50 g or 100 g), which is included in the total weight applied to the spring.
   \n
   \n
\n
2. Slotted Weights: \n
   \n
   • Weights with holes or slots can easily be added or removed from the weight hanger.
   \n
   • Common increments: 50 g, 100 g, 200 g, etc.
   \n
   • It is made of metal, with accurate labeling for precise measurements.
   \n

\n
3. Material: \n
   \n
   • The weight bar and weights are usually made of brass, steel, or aluminum for durability and precision.
   \n
   \n
\n
4. Precision: \n
   \n
   • For experiments, precision is critical, so the weights should be standardized and calibrated.

Usage:

\n
• The weight hanger is attached to the bottom of the spring.
\n
• Weights are incrementally added to the bar, measuring the extension of the spring after each addition.
\n
• The force applied by the weights is calculated by multiplying the mass of the weights by gravity ($F=mg$), where g≈9.8 m/s2g \approx 9.8 \, m/s^2g≈9.8m/s2.
