Double the stretch, and you need double the force. This linear relationship holds for most springs, elastic bands, and many elastic materials \u2014 as long as you stay within their <em>elastic limit<\/em>.<\/p>\n<p>The proportionality constant \\(k\\), called the spring constant or stiffness, tells you how hard a spring resists deformation. A stiff car suspension spring might have \\(k\\) in the hundreds of thousands of N\/m, while a soft toy spring can be just a few N\/m. Importantly, \\(k\\) depends on the material, the coil diameter, the wire thickness, and the number of coils \u2014 it is a property of the specific spring, not of the material alone.<\/p>\n<p>Note that the force in Hooke's law is a <em>restoring<\/em> force: it always points opposite to the displacement. In this calculator, a positive displacement means the spring is stretched, and the resulting positive force is the magnitude of the restoring pull. If you enter a negative displacement (compression), the force is negative, indicating the spring pushes back outward. If you want to explore the energy stored in a deformed spring, see the <a href=\"https:\/\/wpcalc.com\/en\/physics\/elastic-potential-energy-calculator\/\">elastic potential energy calculator<\/a>; for force in general, try the <a href=\"https:\/\/wpcalc.com\/en\/physics\/force-physics\/\">force calculator<\/a>.<\/p>\n<p>Because the formula is a simple proportion, you can use it in any consistent unit system. The calculator converts your inputs to SI units internally, so mixing, say, lbf with inches works correctly \u2014 no manual conversions needed.<\/p>\n<h2>Solving for Each Variable<\/h2>\n<ul>\n<li><strong>Find the force:<\/strong> \\( F = k \\cdot x \\). Multiply the stiffness by the displacement. This is what happens when you know the spring and how far it is deformed.<\/li>\n<li><strong>Find the spring constant:<\/strong> \\( k = F \/ x \\). Divide the applied force by the resulting deformation. This is a common way to measure an unknown spring's stiffness experimentally: hang a known weight and measure how far it stretches.<\/li>\n<li><strong>Find the displacement:<\/strong> \\( x = F \/ k \\). Divide the force by the stiffness. This tells you how far a spring will deform under a given load.<\/li>\n<\/ul>\n<h2>Assumptions, Limitations, and Practical Tips<\/h2>\n<ul>\n<li><strong>Elastic limit:<\/strong> Hooke's law only works while the deformation is reversible. Stretch a spring too far and it deforms permanently; the relationship stops being linear well before that point.<\/li>\n<li><strong>Massless, ideal spring:<\/strong> the model ignores the spring's own weight and internal friction (hysteresis). Real springs dissipate a little energy on each cycle.<\/li>\n<li><strong>Sign conventions:<\/strong> enter positive values for stretching and negative values for compressing. When solving for \\(k\\), the force and displacement must have the same sign \u2014 a stretching force with a negative displacement would imply a negative, physically impossible spring constant, and the calculator will warn you.<\/li>\n<li><strong>Zero inputs:<\/strong> a force or displacement of zero cannot determine \\(k\\) (any stiffness produces zero deformation under zero load), and a spring constant must be greater than zero.<\/li>\n<li><strong>Measuring k in practice:<\/strong> when testing a real spring, take several force\u2013displacement pairs and check that the ratio \\(F\/x\\) is constant \u2014 if it drifts, the spring is leaving its linear range.<\/li>\n<\/ul>\n<h2>Typical Spring Constants<\/h2>\n<table>\n<thead>\n<tr>\n<th>Spring \/ system<\/th>\n<th>Approximate k<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Ballpoint pen spring<\/td>\n<td>~50\u2013200 N\/m<\/td>\n<\/tr>\n<tr>\n<td>Car suspension spring<\/td>\n<td>~20,000\u2013100,000 N\/m<\/td>\n<\/tr>\n<tr>\n<td>Rubber band (small)<\/td>\n<td>~10\u2013100 N\/m<\/td>\n<\/tr>\n<tr>\n<td>Mattress coil<\/td>\n<td>~2,000\u201310,000 N\/m<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Hooke's law also underlies oscillation problems: a mass on a spring exchanges kinetic energy and <a href=\"https:\/\/wpcalc.com\/en\/physics\/elastic-potential-energy\/\">elastic potential energy<\/a>, a case you can analyze with the <a href=\"https:\/\/wpcalc.com\/en\/physics\/conservation-of-energy-calculator\/\">conservation of energy calculator<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Calculate spring force, spring constant, or displacement using Hooke's law (F = k\u00b7x).
