Apparent WeightlessnessA common misunderstanding among many people today is that astronauts experience weightlessness, particularly when doing reference to astronauts in space. Many believe that astronauts are weightless in space, which accounts for their ability to float and travel in space. However, physics has proven this claim to be inaccurate and astronauts only weigh about 10% less in space. According to Cutnell and Johnson, this state of "weightlessness" is not actually weightlessness and should in turn be referred to as apparent weightlessness [1]. In physics, the concepts that best describe apparent weightlessness are uniform circular motion, gravity, and applied force. According to Yale Scientific, without gravity, everything would cease to exist and because all matter would fly away. Gravity is everywhere and it is the strongest force in space and affects all matter. The Earth's gravitational pull is responsible for the Moon's orbit, and this gravitational force causes the planets to orbit the sun. Because the gravitational force relies on two masses, which can explain why objects float freely in space. The smaller the mass, the more left gravitational force is felt. The further the object is from the sun, the weaker its gravitational force. Say no to plagiarism. Get a tailor-made essay on “Why Violent Video Games Should Not Be Banned”? Get the original essay The weight of an object is equal to gravity and the force acting on the object. The “real weight”, which is determined by the equation W=m*g by a weighing machine or scale, the real weight is equal to the force exerted by the Earth on it. An example, when the stone is suspended by a spring balance, the weight is due to the normal contact force between the spring and the stone. If a stone was placed on a scale, the force of gravity or its weight acting downward is the force. The upward normal force exerted by any supported surface is called apparent weight, which depends on the motion of the object or person. Moreover, this further explains that a person in space would have almost the same weight as a person standing on the ground. Another example of weightless astronauts is a person inside an elevator, when the elevator is still the equation of weight equals mass. times gravity and equal to force (W=mg=N), when the elevator descends, mass times acceleration equals mass times gravity minus force (ma=mg-N), and when the elevator moves upward, mass times acceleration equals force minus mass times gravity (ma=N-mg), the weight stays the same. When the elevator is falling freely, the weight is zero because mass times gravity equals mass times gravity minus force (mg=mg-N). Therefore, the apparent weight depends on the movement, during free fall the person and the weighing machine fall with the weight. same acceleration. The astronauts remain in free fall, they exert no force and experience weightlessness. As mentioned above, weightlessness is experienced because the astronaut and the weighing machine are falling freely at the same acceleration, and motion contributes a large part of weightlessness.

Due to free fall, the astronaut has no force to support his body as he accelerates at the same rate as the.
