What is the formula of weight weightlessness?

Weightlessness occurs when an object is in free fall, experiencing no net force acting upon it. The formula for weight (W) is given by W = mg, where m is mass and g is the acceleration due to gravity. In a state of weightlessness, such as in orbit, the gravitational force is still present, but the object is falling at the same rate as its surroundings, resulting in no sensation of weight. Thus, while weight can be calculated, the experience of weightlessness means that the object does not exert a force against a supporting surface.
