When a person is in a lift, they can feel heavier or lighter depending on the direction the lift is moving.

Option 1: If the lift is going down steadily, the person may feel lighter. This is because the downward acceleration of the lift is counteracting the gravitational force, reducing the apparent weight.

Option 2: If the lift just begins to go up, the person may feel heavier. This is because there is an initial upward acceleration, which adds to the gravitational force, making the person feel more weight.

Option 3: If the lift is moving up steadily, the person should not feel any significant change in weight. There is no additional acceleration to affect the apparent weight.

Option 4: If the lift descends freely, without any control or braking, the person may feel lighter. This is due to the absence of an upward force to counteract the gravitational force, resulting in a decrease in perceived weight.

In this case, option 2 is correct. When the lift just begins to go up, there is an initial upward acceleration which makes a person feel heavier.
