The negative sign in the equation F = -kx indicates the action of the restoring force in the string. The variables of the equation are F, which represents force, k, which is called the spring constant and measures how stiff and strong the spring is, and x, the distance the spring is stretched or compressed away from its equilibrium or rest position.The force exerted by a spring is called a restoring force; it always acts to restore the spring toward equilibrium. ","noIndex":0,"noFollow":0},"content":"Any physicist knows that if an object applies a force to a spring, then the spring applies an equal and opposite force to the object. T = 2 (m/k). Assume that the spring was un-stretched before the body was released. When a spring stays within its elastic limit and obeys Hookes law, the spring is called an ideal spring. the rotational analog of spring constant is known as rotational stiffness. [1] Sure, you say. The amount of mechanical energy stored and used by a spring then, is relative to the force and displacementthe harder a spring is pulled, the harder it pulls back. He's written about science for several websites including eHow UK and WiseGeek, mainly covering physics and astronomy. The larger the spring constant, the stiffer the spring and the more .
