You are spending a weekend onboard the International Space Station and you’ve been asked to produce a video of a weightlessness demonstration. However, are you truly weightless? Prepare a response to this question in terms of mass, acceleration to gravity, and weight. Feel free to embellish your account of values but you will need to look up the accelerations due to gravity on Earth (surface) to support your account.
We are not ever truly weightless that sensation is the result of falling. Weight is the force of gravity exerted on an object. Mass is the measure of how much an object can resist velocity. Acceleration to gravity is the value assigned to an object that is free-falling towards earth. If you were to jump out of a plane and free fall that would create the feeling of weightless. Riding rollercoasters can give the feeling of weightlessness when it goes straight down that is part of the thrill. When in an elevator and it goes it gives the feeling of weightlessness even though the elevator still has the same weight as it goes up.
