Weightlessness, a sensation of floating freely without any gravitational pull, can occur in various scenarios. In the absence of gravity or when the gravitational force acting upon an object is negligible, a state of weightlessness can be experienced. This phenomenon can be observed in situations such as freefall, where an object is in motion and not in direct contact with any surface or when submerged in a fluid, as the buoyant force counteracts the gravitational pull. Additionally, individuals participating in spaceflight missions experience weightlessness due to the microgravity environment created by the Earth’s orbit.
