The best way to understand their relationship is through the <strong>Work-Energy Theorem<\/strong>, which states:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><em>The work done on an object is equal to the change in its energy.<\/em><\/p>\n<\/blockquote>\n\n\n\n<p>This is why the correct answer is <strong>(e): &#8220;The change in an object&#8217;s energy is the work done on that object.&#8221;<\/strong><\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Work Defined:<\/strong><\/h4>\n\n\n\n<p>In physics, <strong>work<\/strong> is done when a <strong>force<\/strong> is applied to an object and the object <strong>moves in the direction<\/strong> of that force. Mathematically, it is given by:W=F\u22c5d\u22c5cos\u2061(\u03b8)W = F \\cdot d \\cdot \\cos(\\theta)W=F\u22c5d\u22c5cos(\u03b8)<\/p>\n\n\n\n<p>Where:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>WWW is the work done,<\/li>\n\n\n\n<li>FFF is the force applied,<\/li>\n\n\n\n<li>ddd is the displacement,<\/li>\n\n\n\n<li>\u03b8\\theta\u03b8 is the angle between the force and displacement vectors.<\/li>\n<\/ul>\n\n\n\n<p>Work is measured in <strong>joules (J)<\/strong>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Energy Defined:<\/strong><\/h4>\n\n\n\n<p><strong>Energy<\/strong> is the capacity to do work. There are many forms of energy: kinetic, potential, thermal, chemical, etc. When work is done <strong>on<\/strong> an object, its energy changes. For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>When you lift a book, you do work against gravity, increasing its <strong>gravitational potential energy<\/strong>.<\/li>\n\n\n\n<li>When you push a sled, you do work to increase its <strong>kinetic energy<\/strong>.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Why the Other Options Are Incorrect:<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>(a)<\/strong>: While work and energy share the same unit (joules), they are not <em>exactly<\/em> the same. Energy is a broader concept; work is a process that transfers energy.<\/li>\n\n\n\n<li><strong>(b)<\/strong>: Energy is not &#8220;equivalent to the change in work&#8221;; rather, work causes a change in energy.<\/li>\n\n\n\n<li><strong>(c)<\/strong>: Energy and work are very much related, so this is false.<\/li>\n\n\n\n<li><strong>(d)<\/strong>: There&#8217;s no such equation involving mass and &#8220;work done squared.&#8221;<\/li>\n<\/ul>\n\n\n\n<p>In summary, <strong>work<\/strong> is a <strong>mechanism<\/strong> through which <strong>energy is transferred or transformed<\/strong>.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner4-542.jpeg\" alt=\"\" class=\"wp-image-227908\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following statements best describes the relationship between work and energy?
