HORTICULTURE DEVELOPMENT OF‐ FICER(HDO) -2015 The apparent weight of a person in a lift is affected by the lift's acceleration. - Upward acceleration Apparent weight > Actual weight (feeling heavier). - Downward acceleration Apparent weight Zero acceleration (steady motion) Apparent weight = Actual weight (feeling normal). - Free fall Apparent weight = 0 (feeling weightless).When the lift "just begins to go up," it has an upward acceleration.
One feels heavier in a lift when the lift— [A] is going down steadily [B] just begins to go up [C] is moving up steadily [D] descends freely
