It is called acceleration, while <strong>act and result of accelerating<\/strong> Yet the <strong>magnitude<\/strong> which refers to <strong>change of velocity in a unit of time<\/strong>. <\/p>\n<p>Notably <strong>speed up<\/strong> is the action that is developed to <strong>increase the<\/strong> <strong>speed<\/strong>.  Speed \u200b\u200bis called, on the other hand, the magnitude that reveals the distance traveled by a body in a time unit.<\/p>\n<p>In short, accelerating something (a car, for example) involves increasing its speed.  This is how it is achieved that what was accelerated moves faster, traveling more meters in less <strong>weather<\/strong>.  The accelerometer, in this framework, is the instrument that can measure acceleration.<\/p>\n<div id=\"attachment_81824\" style=\"width: 650px\" class=\"wp-caption alignnone\"><img decoding=\"async\" loading=\"lazy\" aria-describedby=\"caption-attachment-81824\" loading=\"lazy\" src=\"https:\/\/enorcerna.com\/wiki\/wp-content\/uploads\/2021\/10\/acelerometro.jpg\" alt=\"Acceleration\" width=\"640\" height=\"419\" class=\"size-full wp-image-81824\"  \/><\/p>\n<p id=\"caption-attachment-81824\" class=\"wp-caption-text\">An accelerometer is used to measure acceleration.<\/p>\n<\/div>\n<h2>How an accelerometer works<\/h2>\n<p>The accelerometer is also referred to as <strong>acceleration sensor<\/strong>.  This is because, precisely, it consists of a <strong>sensor<\/strong> which measures how much something is speeding up or slowing down.<\/p>\n<p>To fulfill its function, the accelerometer relies on the acceleration applied on a <strong>mass<\/strong> located in balance between springs.  This process generates vibrations in the dough.<\/p>\n<p>When vibrating, then, the mass compresses a <strong>piezoelectric material<\/strong> and there is a <strong>electric charge<\/strong>.  In this way, the <strong>vibration level<\/strong> generated by the <strong>displacement<\/strong>.<\/p>\n<p>In other words: the acceleration causes the mass to compress the piezoelectric material, producing an electrical charge that is proportional to the force exerted.  Since the load is proportional to the <strong>strength<\/strong> and the mass is constant, the charge in turn is proportional to the acceleration.<\/p>\n<div id=\"attachment_81825\" style=\"width: 650px\" class=\"wp-caption alignnone\"><img decoding=\"async\" loading=\"lazy\" aria-describedby=\"caption-attachment-81825\" loading=\"lazy\" src=\"https:\/\/enorcerna.com\/wiki\/wp-content\/uploads\/2021\/10\/velocidad.jpg\" alt=\"Car\" width=\"640\" height=\"414\" class=\"size-full wp-image-81825\"  \/><\/p>\n<p id=\"caption-attachment-81825\" class=\"wp-caption-text\">In a car, an accelerometer can provide information about the brakes or activate the airbag.<\/p>\n<\/div>\n<h2>Device uses<\/h2>\n<p>Typically, the accelerometer is used in heavy vehicles such as <strong>planes<\/strong> or <strong>trains<\/strong> and in different <strong>machines<\/strong>.  Its use is not so common in <strong>automobiles<\/strong>, although it can help to analyze how effective are the <strong>brakes<\/strong>, for instance.<\/p>\n<p>In modern cars, the accelerometer can be linked to the <strong>airbag<\/strong>.  A car that brakes sharply and abruptly registers a strong deceleration;  When the sensor detects this change, it can transmit the <strong>information<\/strong> to deploy the airbag almost immediately.<\/p>\n<p>On the other hand, an accelerometer, by monitoring the vibrations of a machine, can provide valuable data on the <strong>state<\/strong> of its rotating elements.  Another possibility is to carry out a structural test with the accelerometer to discover, from the vibrations, the safety conditions of a tank, a turbine or an engine.<\/p>\n<h2>The accelerometer on the phone<\/h2>\n<p>The <strong>smart phones<\/strong>, known in English as <strong>smartphones<\/strong>, have various sensors.  One of them is the accelerometer, which is used to measure the change in speed due to movement or due to <strong>gravity<\/strong>.<\/p>\n<p>With the accelerometer, the phone can <em>\"perceive\"<\/em> a modification of your orientation or your <strong>position<\/strong>.  Cell phones or mobiles usually have a <strong>three axis accelerometer<\/strong>, thus identifying the orientation of the equipment with respect to the earth's surface.<\/p>\n<p>It is important not to confuse the accelerometer with the <strong>gyroscope<\/strong>.  While the accelerometer measures acceleration, the gyroscope studies spatial orientation.  For this it resorts to a rotor (a disk that rotates freely), located on a rotating shaft that is installed in the center of a wheel.  On the phone, accelerometer and gyroscope complement each other.<\/p>\n<\/p><\/div>\n\n\n<div class=\"kk-star-ratings kksr-auto kksr-align-center kksr-valign-bottom\"\n    data-payload='{&quot;align&quot;:&quot;center&quot;,&quot;id&quot;:&quot;5629&quot;,&quot;slug&quot;:&quot;default&quot;,&quot;valign&quot;:&quot;bottom&quot;,&quot;ignore&quot;:&quot;&quot;,&quot;reference&quot;:&quot;auto&quot;,&quot;class&quot;:&quot;&quot;,&quot;count&quot;:&quot;0&quot;,&quot;legendonly&quot;:&quot;&quot;,&quot;readonly&quot;:&quot;&quot;,&quot;score&quot;:&quot;0&quot;,&quot;starsonly&quot;:&quot;&quot;,&quot;best&quot;:&quot;5&quot;,&quot;gap&quot;:&quot;4&quot;,&quot;greet&quot;:&quot;Rate this post&quot;,&quot;legend&quot;:&quot;0\\\/5 - (0 votes)&quot;,&quot;size&quot;:&quot;24&quot;,&quot;title&quot;:&quot;accelerometer&quot;,&quot;width&quot;:&quot;0&quot;,&quot;_legend&quot;:&quot;{score}\\\/{best} - ({count} {votes})&quot;,&quot;font_factor&quot;:&quot;1.25&quot;}'>\n            \n<div class=\"kksr-stars\">\n    \n<div class=\"kksr-stars-inactive\">\n            <div class=\"kksr-star\" data-star=\"1\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"2\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"3\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"4\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"5\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n    <\/div>\n    \n<div class=\"kksr-stars-active\" style=\"width: 0px;\">\n            <div class=\"kksr-star\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" style=\"padding-right: 4px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n    <\/div>\n<\/div>\n                \n\n<div class=\"kksr-legend\" style=\"font-size: 19.2px;\">\n            <span class=\"kksr-muted\">Rate this post<\/span>\n    <\/div>\n    <\/div>\n","protected":false},"excerpt":{"rendered":"<p>A accelerometer is a device that allows the measurement of acceleration.
