Normal force (N) in an upward accelerating lift

The normal force acting on an object in an upward accelerating lift equals the weight (mg) plus the mass (m) times the acceleration (a) of the lift. N = mg + ma

Normal force (N) in a downward accelerating lift

The normal force acting on an object in a downward accelerating lift equals the weight (mg) minus the mass (m) times the acceleration (a) of the lift. N = mg - ma

Derivation of acceleration in a lift

By equating the normal force (N) in an upward and downward accelerating lift, we find that the acceleration (a) is equal to g/2, where g is the acceleration due to gravity.
