It arises <strong>only when interactions between parts of the system are considered<\/strong>. Therefore, <strong>option (e)<\/strong> \u2014 <em>interactions are included within the system<\/em> \u2014 is the correct choice.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To understand this better, consider that potential energy is not an inherent property of a single object but rather a property of a <strong>system of objects<\/strong> that interact via <strong>conservative forces<\/strong> such as gravity, spring (elastic) force, or electrostatic force. These interactions store energy in a potential form. For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A mass held above the ground has gravitational potential energy due to its interaction with Earth\u2019s gravitational field.<\/li>\n\n\n\n<li>A compressed spring has elastic potential energy due to the interaction between the spring\u2019s particles resisting deformation.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">When <strong>interactions are excluded<\/strong>, the potential energy concept breaks down because the system no longer stores energy due to configuration or position. Without considering interactions, we can only account for kinetic energy or thermal energy, not potential energy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Let\u2019s evaluate the other options:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>(a) &#8220;we consider only conservative forces&#8221;<\/strong> \u2013 Conservative forces like gravity are indeed associated with potential energy, but just considering them isn\u2019t enough; <strong>interactions<\/strong> must still be included.<\/li>\n\n\n\n<li><strong>(b) &#8220;the system is isolated&#8221;<\/strong> \u2013 Isolation prevents energy exchange with the surroundings but doesn\u2019t determine the presence of potential energy.<\/li>\n\n\n\n<li><strong>(c) &#8220;thermal energy can be neglected&#8221;<\/strong> \u2013 Neglecting thermal energy helps simplify analysis but does not cause potential energy to arise.<\/li>\n\n\n\n<li><strong>(d) &#8220;the work from external forces is zero&#8221;<\/strong> \u2013 This condition relates to conservation of energy, not the presence of potential energy.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In conclusion, <strong>potential energy exists when the internal interactions among the system&#8217;s components are taken into account<\/strong>, making option <strong>(e)<\/strong> the most accurate.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Potential energy arises when_____________. a. we consider only conservative forcesb. the system is isolatedc. thermal energy can be
