what does a spring scale measure

A spring scale can not measure mass, only weight. A spring scale is a scale which measures weight by determining the deflection of a spring. Kitchen scales are available in balance or spring models. And springs are used to measure force. It usually has a pan, a hook and half the weight of the spring pulling on it. A spring scale measures the weight of an item by opposing the force of gravity through the force of an extended spring. How scales work. As you watch it, compare the teacher's solution to yours. This relationship is usually linear; i.e., if the load is doubled, the deformation is doubled. Small scales with sensitive springs can be used to measure differences of up to a gram or less, though these will break if heavy weights were attached to them. The spring scale simply measures the tension , the magnitude of the force exerted by the string. You may think a spring scale measures weight, and for most intents and purposes you can get away with pretending it does. 4. The simplest form of spring scale (a typical fish scale) is a spring hanging from a handle or hook with a ruler to measure the length of the spring. This is top of my head stuff but I hope it helps. a) Calculate how much a 70 kg person weigh a) if the elevator accelerates upward with a rate of +1.00 m/s2, b) if the elevator accelerates downward with a rate of -1.00 m/s2. When you step onto it, the springs inside the device are compressed, and move the circular dial with the weight inscriptions the amount proportional to the force your mass applies on the springs. So when you are using it to measure mass, you are actually measuring the force which the earth exerts on the mass. How does it work? What do you use a spring scale to measure? 3. Normally it will be a measure of force. The function of a spring scale is based on Hooke’s Law. Spring scales are designed to take advantage of Hooke's law to determine the size of the force stretching the spring by measuring the displacement. How does a spring scale measure weight? Spring or stress-gauge scales (the usual bathroom type) naturally measure weight and have a scale that effectively divides by some assumed value of g to give a value of mass. Hooke’s Law states that the force exerted on a spring is directly proportional to the distance it moves as a result of the force. Dictionary entry overview: What does spring scale mean? It consists of a spring fixed at one end with a hook to attach an object at the other. 1 Newton=100 Grams ; To Use a Spring Scale: First, make sure the indicator lines up with the top of the zero line. It needs to be calibrated perfectly to measure the force accurately. The student will demonstrate the ability to measure the force of gravity using a spring scale in Newton units and also determine the mass of each item using a balance scale. Spring scales, for example, measure weight using Hooke's law, which relates force (weight) to the stretching or compression of a spring made from a given material. there is no electronic form to submit.). This can be a bit confusing, but it's acceptable because (as explained above) weight and mass are connected … 2. Since a spring will naturally slacken after repeated stretching, the scale needs to be replaced after a while, since a slackened spring will give erroneous results. Part II, What does a spring scale measure? If you move them to another planet they'll be wildly inaccurate because the assumed g won't be applicable any more. To Use a Spring Scale: 1. The traditional scale consists of two plates or bowls suspended at equal distances from a fulcrum. Weight is a force (the force of gravity acting on a mass). A spring scale measures weight or force by hanging objects from its hook, making it an easy way for kids to see how weighing works. Watch What does a spring scale measure?

Prerequisite: Continue reading through section 5.6 down to but not including Example 5-6. That is what the reading on the scale indicates. If it does not, use the metal tab or the nut at the top of the spring scale to adjust it. (b) The resistance of the spring to deformation causes a force, F restore to be exerted back on whatever is pulling on the hook. Not all scales use springs, but all measure weight using mechanical components. Part II. In its simplest form, it is just a spring attached at one end and a pointer on a scale at the other. We hope you are enjoying ScienceStruck! The obvious answer is kilograms (or grams). First, make sure the indicator lines up with the top of the zero line. The unit of force on the scale will depend on the calibration of the spring balance.
