That action heats up your skin and provides immediate comfort. But if you look at the <strong>law of energy<\/strong> behind it, you\u2019ll discover a fundamental truth about our universe.<\/p>\n\n\n\n<p>When we rub our hands, we use mechanical energy to create friction, which generates heat. This heat doesn\u2019t appear out of thin air; you are converting mechanical energy into thermal energy.

At the bottom of the swing, its kinetic energy is at its peak.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"4How_do_you_define_law_of_conservation_of_energy_for_a_middle_school_student\"><\/span>4.How do you define law of conservation of energy for a middle school student?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ol start=\"4\" class=\"wp-block-list\">\n<li><\/li>\n<\/ol>\n\n\n\n<p>&nbsp;Ans- To <strong>define law of conservation of energy<\/strong> for younger students: &#8220;Think of energy like a set of building blocks.

In a <strong>law of conservation of energy lab<\/strong>, friction often turns kinetic energy into thermal energy (heat). This heat radiates into the environment, so while the machine might slow down, the energy still exists in the universe as heat.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"7How_to_calculate_potential_energy_in_a_conservation_problem\"><\/span>7.How to calculate potential energy in a conservation problem?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ol start=\"7\" class=\"wp-block-list\">\n<li><\/li>\n<\/ol>\n\n\n\n<p>&nbsp;Ans- To understand <strong>how to calculate potential energy<\/strong>, use the formula U = mgh.
