Weightnessless is a type related to gravitational force.
Explanation:
WEIGHTLESSNESS: If the gravitational force W of the power standing in the lift acts downwards and the reaction force R applied upwards, then both these forces will be in opposite direction, hence net force on the person, F = W - R downwards.
If the lift is stationary or moving with the same velocity up or down, then F = O and W = R
If the lift is moving upwards with the same acceleration, a, then F = ma where m is the mass of the person.
R = W + ma
In this case the virtual weight of the person is more than his actual weight mg.
