Even in a state of weightlessness, gravity is still acting on you. For example, in orbit, an astronaut is still subject to Earth’s gravitational pull, but they are in freefall. This means that the astronaut is accelerating toward the Earth due to gravity, but because they are moving forward at a high enough speed (orbital velocity), they continuously fall around the Earth instead of directly toward it. This creates the sensation of floating or weightlessness.<\/li>\n\n\n\n
Normally, when standing on a surface, your body is exerting a downward force due to gravity (your weight), and the surface exerts an equal and opposite force upward, known as the normal force. This normal force is what you feel as your weight. However, during freefall or in orbit, there is no surface pushing up on you (no normal force), which causes the sensation of weightlessness, as there is nothing counteracting gravity that you can sense.<\/li>\n\n\n\n
Apparent weight refers to the sensation of weight that you feel. In situations like a roller coaster ride or freefall, although gravity still acts on you, there is no support force (normal force), so you feel weightless. Your apparent weight is effectively zero, even though the force of gravity is still present.<\/li>\n<\/ol>\n\n\n\n
