Hooke's Law Describes the force exerted by a spring, proportional to its displacement from equilibrium. Spring Constant A measure of a spring's stiffness, denoted by 'k', in newtons per meter (N/m). Equilibrium Position The position where a spring is neither compressed nor stretched, and displacement is zero. Deformation The change in length of a spring from its equilibrium position, denoted by 'x'. Restoring Force The force exerted by a spring that acts to return it to its equilibrium position. Applied Force The external force applied to compress or stretch a spring. Action-Reaction Pair A pair of forces where one is the action and the other is the equal and opposite reaction. Variable Force A force that changes in magnitude or direction over time, such as spring force. Work Done by Spring Calculated as negative one half k x squared, representing energy stored or released. Magnitude The size or amount of a quantity, ignoring its direction. Compression The act of pressing a spring into a smaller length than its equilibrium position. Displacement The distance and direction from the equilibrium position to the current position. Cosine Theta A trigonometric function used to calculate work, based on the angle between force and displacement. Average Force The mean value of a variable force over a displacement, used in work calculations. Joules The unit of work or energy in the International System of Units (SI).
