It always dissipates mechanical energy as heat, which cannot be recovered, unlike conservative forces.<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>Complete Answer:<\/strong> <\/p>\n\n\n\n<p>A force is called conservative if the work done by or against the force does not depend on the path taken but only on the initial and final positions. Also, for a conservative force, the net work done in a complete round trip (closed path) is zero.<\/p>\n\n\n\n<p>But in the case of friction, the work done depends on the path taken. The longer the path, the more work is needed to overcome friction. Also, when an object moves in a closed path and comes back to its starting point, friction still does work, and energy is lost as heat. This means that the work done by friction is not recovered.<\/p>\n\n\n\n<p>So, friction always opposes motion and causes loss of mechanical energy in the form of heat. This energy cannot be regained, which is a key feature of non-conservative forces.<\/p>\n\n\n\n<p>Therefore, friction is a non-conservative force because it depends on the path and leads to energy loss.<\/p>\n\n\n\n<p>Friction is not a conservative force, to be clear.&nbsp; A conservative force just depends on the position of the object; it is not affected by the path.&nbsp; Friction is non-conservative since the amount of work it does depends on directions.<\/p>\n\n\n\n<p>There is no potential energy associated with non-conservative forces since the energy is lost to the system and cannot be transformed into meaningful work later.\u00a0 This means that every potential energy has a conservative force attached to it.<\/p>\n\n\n\n<p class=\"has-text-align-center has-vivid-red-color has-text-color has-link-color has-medium-font-size wp-elements-896a73f978ab2ff6c446e129d82149f7\"><strong>Common Physics Doubts:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><tbody><tr><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/20-degrees-fahrenheit-to-celsius\/\"><strong>20 degrees Fahrenheit to Celsius<\/strong><\/a><\/td><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/similarities-and-differences-between-the-laboratory-thermometer-and-the-clinical-thermometer\/\"><strong>State similarities and differences between the laboratory thermometer and the clinical thermometer<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/what-is-the-basic-difference-between-the-terms-electron-gain-enthalpy-and-electronegativity-class-11-physics-cbse\/\"><strong>What is the basic difference between the terms electron gain enthalpy and electronegativity?<\/strong><\/a><\/td><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/unit-of-magnetic-pole-strength-in-the-m-k-s-system-class-11-physics-cbse\/\"><strong>What is the unit of magnetic pole strength in the M.K.S. system?<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/the-colour-of-the-earth-wire-is-generally\/\"><strong>The colour of the earth wire is generally<\/strong><\/a><\/td><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/what-is-the-speed-of-earths-rotation-and-revolution-class-11-physics-cbse\/\"><strong>What is the Speed of Earth\u2019s Rotation and Revolution?<\/strong><\/a><\/td><\/tr><\/tbody><\/table><\/figure>\n","protected":false},"excerpt":{"rendered":"Answer: No, friction is not a conservative force because the work it does depends on the path taken,&hellip;\n","protected":false},"author":83,"featured_media":3029,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"editor_notices":[],"footnotes":""},"categories":[7,4],"tags":[],"class_list":{"0":"post-3005","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-physics","8":"category-science"},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Is friction a conservative force?
