WebSep 27, 2012 · Hooke's law describes a certain light spring of unstretched length 37.0 cm. When one end is attached to the top of a door frame and a 8.00-kg object is hung from the other end, the length of the spring is 40.5 cm. (a) Find its spring constant. (b) The load and the spring are taken down. WebWhen is Hooke's law positive? Whenever I use this law, I always take F = -k*x. Hooke’s law will give a positive value for the force whenever your displacement is negative. In other words, if you are compressing a spring, your value for force will be positive.

WebMy aim is to investigate Hooke’s law, using masses and springs. When weights are attached to one end of a spring it stretches. Hooke’s law states that the extension depends directly on the load, that is: Extension (E) is proportional to the load (M) added. So if this is true doubling the load should double the extension. WebHooke’s Law Equation The length of a spring always changes by the same amount when it is pushed or pulled. In the case of a linear spring being pushed or pulled in one direction, the …

WebThe work you do when stretching or compressing a spring a distance x from its equilibrium position therefore is W = ½kx 2. Problem: When a 4 kg mass is hung vertically on a certain light spring that obeys Hooke's law, the spring stretches 2.5 cm. If the 4 … WebThe spring force is called a restoring force because the force exerted by the spring is always in the opposite direction to the displacement. This is why there is a negative sign in the Hooke’s law equation. Pulling down on a spring stretches the spring downward, which …
