fightdistrict on Instagram: "In an MIT physics lecture on free fall and weightlessness, Professor Walter Lewin demonstrated the idea in a striking and unforgettable way. He began by holding a stone and explaining that while standing still, his hand applied an upward normal force equal to the stone’s weight (mg), keeping it at rest. Then, to show what changes in free fall, he jumped off a table while still holding the stone. During the fall, both he and the stone accelerated downward together und

Explain Education on Instagram: "When an object is in free fall, gravity is the only force acting on it. Prof. Walter Lewin explains that weightlessness is not due to the absence of gravity, but because both the object and its surroundings are falling at the same rate. Since there is no supporting force (like the ground pushing up on you), you feel weightless even though gravity is still pulling you downward."

Detailed Explanation on Instagram: "Weightlessness during free fall occurs because you and the environment around you are both accelerating toward the ground at the same rate, which removes the normal supporting force your body is used to feeling. When you stand on the ground or sit in a chair your body feels weight because the surface pushes upward on you, creating the sensation of heaviness. During free fall there is no upward push because you are not resting on anything. Even though gravity i
