In this condition, a person does not feel their weight because there is no external force (like the ground or a chair) pushing against them. Let\u2019s analyze each scenario:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>While accelerating downward in an elevator<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>If the elevator is accelerating downward, you will feel lighter, but not completely weightless unless the elevator is in free fall (falling with the acceleration of gravity, 9.8 m\/s\u00b2). If the elevator were in complete free fall (which is rare), then you would experience weightlessness.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>While falling from a roof (Correct Answer)<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>When falling freely from a roof, both you and your surroundings are accelerating downward at the same rate due to gravity (9.8 m\/s\u00b2). There is no normal force acting on you, and you experience true weightlessness, similar to astronauts in orbit.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>While walking on the Moon<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>On the Moon, gravity is weaker than on Earth (about 1\/6th of Earth&#8217;s gravity), so you feel lighter, but you are still experiencing weight due to the Moon\u2019s gravitational pull. This is not true weightlessness.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>While parachuting from an airplane<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Before opening the parachute, you are in free fall and experience weightlessness. However, as soon as air resistance builds up, your descent slows, and you feel a force acting on you again. Once the parachute opens, you no longer feel weightless because air resistance provides a counteracting force.<\/li>\n<\/ul>\n\n\n\n<p>Thus, <strong>falling from a roof<\/strong> is the scenario where you truly experience weightlessness.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In which of the following cases would you feel weightless? while accelerating downward in an elevatorwhile falling from a roofwhile walking on the Moonwhile parachuting from an airplane The correct answer and explanation is : The correct answer is: while falling from a roof.
