Bars:<\/h3>\n<ol>\n<li><strong>Weight Hanger<\/strong>:\n<ul>\n<li>A bar or rod designed to hold weights securely.<\/li>\n<li>Often made of metal, lightweight, with hooks or clips to attach to the spring.<\/li>\n<li>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.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Slotted Weights<\/strong>:\n<ul>\n<li>Weights with holes or slots can easily be added or removed from the weight hanger.<\/li>\n<li>Common increments: 50 g, 100 g, 200 g, etc.<\/li>\n<li>It is made of metal, with accurate labeling for precise measurements.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Material<\/strong>:\n<ul>\n<li>The weight bar and weights are usually made of brass, steel, or aluminum for durability and precision.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Precision<\/strong>:\n<ul>\n<li>For experiments, precision is critical, so the weights should be standardized and calibrated.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<h3>Usage:<\/h3>\n<ul>\n<li>The weight hanger is attached to the bottom of the spring.<\/li>\n<li>Weights are incrementally added to the bar, measuring the extension of the spring after each addition.<\/li>\n<li>The force applied by the weights is calculated by multiplying the mass of the weights by gravity (<span class=\"katex\"><span
