To find the spring constant (k), use Hooke's Law: k = F / x, where F is the force applied in Newtons (N) and x is the displacement in meters (m). Measure the force and displacement, then divide the force by the displacement to calculate the spring constant.
FAQs & Answers
- What is Hooke's Law? Hooke's Law states that the force exerted by a spring is directly proportional to the displacement from its equilibrium position, represented by the equation F = k * x, where F is the force, k is the spring constant, and x is the displacement.
- How can I measure the spring constant experimentally? To measure the spring constant experimentally, hang a known weight from the spring, measure the displacement from its resting position, and use the formula k = F / x, where F is the weight in Newtons and x is the displacement in meters.
- What units are used for spring constant? The spring constant (k) is measured in Newtons per meter (N/m), indicating how much force is needed to extend or compress the spring by one meter.
- Can spring constant vary? Yes, the spring constant can vary depending on the material and dimensions of the spring, as well as its previous usage. Springs can behave non-linearly after being overstretched or compressed beyond their elastic limit.
