As the apple falls, air resistance acts on it, converting some of the kinetic energy into heat energy transferred to the surrounding air. Upon hitting the ground, the remaining kinetic energy is rapidly converted into sound energy (the impact sound) and heat energy due to the deformation and friction of the apple and the ground. Option C correctly shows the initial conversion from GPE to KE, followed by the dissipation of energy from KE into heat (to air and apple\/ground) and sound upon impact. While heat to air occurs *during* the fall and sound\/impact heat occurs *at the end*, option C provides the most plausible sequence among the choices, suggesting that the kinetic energy is the source from which heat to air, heat to apple, and sound energy arise.<br \/>\n<\/section>\n<section id=\"pyq-additional-information\">\nEnergy transformation during a fall is a classic example of the conservation of energy principle, where potential energy is converted into other forms. In realistic scenarios, dissipative forces like air resistance and the inelastic nature of collisions convert mechanical energy (potential and kinetic) into non-mechanical forms like heat and sound. The order in the options is not strictly temporal for the final dissipation forms, but C best represents the conversion path from potential to kinetic, and then the subsequent forms derived from kinetic energy.<br \/>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>The correct sequence of energy transfer that occurs when an apple falls to the ground is [amp_mcq option1=&#8221;Gravitational potential energy $\\to$ heat energy to air $\\to$ kinetic energy $\\to$ heat energy to ground and apple $\\to$ sound energy&#8221; option2=&#8221;Gravitational potential energy $\\to$ sound energy $\\to$ heat energy to air $\\to$ heat energy to ground and &#8230; <\/p>\n<p class=\"read-more-container\"><a title=\"The correct sequence of energy transfer that occurs when an apple fall\" class=\"read-more button\" href=\"https:\/\/exam.pscnotes.com\/mcq\/the-correct-sequence-of-energy-transfer-that-occurs-when-an-apple-fall\/#more-87640\">Detailed Solution<span class=\"screen-reader-text\">The correct sequence of energy transfer that occurs when an apple fall<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1093],"tags":[1119,1129,1128],"class_list":["post-87640","post","type-post","status-publish","format-standard","hentry","category-upsc-nda-1","tag-1119","tag-mechanics","tag-physics","no-featured-image-padding"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>The correct sequence of energy transfer that occurs when an apple fall<\/title>\n<meta name=\"description\" content=\"The correct answer is C) Gravitational potential energy $to$ kinetic energy $to$ heat energy to air $to$ heat energy to apple $to$ sound energy.
