what does a scale measure

Are you able to help me? To help you differentiate the two, here are the scientific definitions for both weight and mass. And how does it convert Newtons into kilograms? As the person applies more force, the scale will respond by measuring the total normal force. However, you cannot use the same scale on any other planet to measure your mass, as you have to adjust the conversion of Newtons into kilograms according to the gravity of each planet. Does your mass change when you travel to the moon? When you step on the scale, a small electrical current runs up through your leg and across your pelvis, measuring the amount of resistance from body fat. Ask Question Asked 7 years, 5 months ago. The scale actually measures the size of the spring to calculate the force. So, how does it do it? How scales work. The force is not normally displayed on a scale label and instead the conversion of the force to mass is shown. The scales actually measure the force, which, if you remember your science class in high school, is measured in Newtons. On Earth if you have a mass of 98kg your weight is 98 x 9.81 Newtons. Scales measure the weight of material placed on the scale due to gravity producing a force on the mass of the material. And springs are used to measure force. However, the scale is not measuring our mass. Your email address will not be published. You will have reduced the total mass of material on the scales by 50% when you removed one of the coins. See my video on Hooke’s law to see this in action. Well, technically, it isn’t because kilogram or pounds are measuring units of mass. From your example one could infer that the scale calculates a person’s mass from the weight given to it. Although distance doesn’t seem that important in this case. Then should I confidently say that my mass is 90 Kg weighed on weighing machine? Isn’t the answer to the question, “What does a scale measure?” quite obvious? We are not using the scales to measure the mass directly. Thanks Professor Postal Scale vs Kitchen Scale: Which Is Better for Delivery Businesses? Di or iDmeasures an active, fast-paced disposition using adjectives such as dynamic, adventurous, and bold. The answer is not as obvious as you initially thought, right? For example, if the scale factor is 1:8 and the real measurement is … Scales measure how much something weighs—and they do it by measuring how much force exists between the object you're weighing and planet Earth. Also, if i get rid of my mass, will i float? It just measures the force, which is our weight. Inside a mechanical scale is a spring. See the section starting with the title “What do scales measure?”. This means that the scale is showing you a wrong measurement of your mass, as it fails to convert the weight into mass due to change in gravity. The reading on the scale may have been calibrated so that it converts this force into mass. A balance or scale is an instrument used to measure mass in the science laboratory. So do we get a value that is divided by acceleration due to gravity or we get a value on the scale that includes the value of g. Hi Meriam, The scale is calibrated, which means that a force is applied to it and then the scale is created to provide this reading in kg to give a mass reading. The spring measures the normal force on the scale. Powered by  - Designed with the Hueman theme. This means that our scale measures mass even when it uses the mechanism that calculates the force you exert, but later convert it into kilograms. 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. it was my very big confusion between weight and mass which is showing in scale. In digital scales, the modern technology is used to convert the difference in the size of the springs into the weight displayed on the screen. Hi Doug. With this in mind, a 1:1 (“one to one”) scale is the real world scale of everything, and the scale that we draw and 3D model in when using CAD and 3D programmes (…more on this below). Dear Professor, So a kg scale is calibrated to give out its readings in mass but a pound scale gives out its readings in force? You will suddenly see the scale reading increasing, indicating that your mass has increased. Thanks a million Professor for your examples and quick responses to queries. If the scale reads in kg, how do you convert it to Newtons if the kg reading is not mass. eval(ez_write_tag([[250,250],'yourweighingbuddy_com-large-leaderboard-2','ezslot_4',127,'0','0']));As mentioned above, the measuring unit for weight or force is Newton. Thank you for the explanation. What is it -my mass or weight? The interval scale is the third level of measurement and encompasses both nominal and ordinal scales. The way they measure force is through the fact that if you shorten the length of a spring, a force is required. Wyze Scale can measure the 12 body composition metrics below. I have a mass, so do i produce gravity? Learn how your comment data is processed. When you weigh yourself on scales the display is actually showing your mass in kg even though it is measuring your weight. We can convert a scale “weight” of kg (mass) to pounds (force) by multiplying by ~2.2. It is based on orders of magnitude, rather than a standard linear scale, so each mark on the decibel scale is the previous mark multiplied by a value. Active 7 years, 5 months ago.
