only if it equaled acceleration due to gravity (about 9.8 (m/s)/s)

Why does weight on an elevator change though you don't leave earths gravity?
If the elevator accelerates, the acceleration will provide an additional apparent force.
What are the two forces acting on a person as they move up and down in an elevator and when are these two forces equal and when are they not equal?
When the elevator is still the force of gravity due to your weight pressing downwards on the floor is equalled exactly by the floor pushing you upwards with the same force. When the elevator rises you feel a little heavier, and the elevator is pushing upwards with the same increased force. When the elevator descends you feel that you lose a little weight, and the floor pushes up at you with the equally reduced force, so you descend.
Is the apparent molecular weight of air at elevation same as at sea level?
The apparent molecular weight of a mixture of ideal gases depends on the concentrations of such gases in the Atmosphere. Below 100km altitude the gases in the atmosphere are very well mixed so that the concentration of all the gases does not vary (approximately) with altitude. Therefore the apparent molecular weight would not vary very much at an elevation and at sea level.
How does an object change with gravity?
An object with mass will be accelerated by a gravitational force.If the object were (relatively) stationary, but the gravitational force changed, then the apparent weight would change.
What is achimedes principle?
Archimedes principle states that any immersed body in a fluid will experience a buoyant force which is equal to the weight of fluid displaced by it and always acts upwards through the centroid of displaced volume. Note that if the object weight less than the wieght of water it displaces, it will float. If it is heavier than the weight of water it displaces, it will sink but its apparent weight in water will be its in-air weight minus the weight of the water it displaces.
Why does weight on an elevator change though you don't leave earths gravity?

In an elevator when is your apparent weight less than your real weight?
When the lift is accelerating downwards. See related question.
When going up in an elevator your weight reported by a scale increases?
Not really. It is not the fact of GOING UP that makes your apparent weight increase, but the fact that it is ACCELERATING UPWARD. For example, while the elevator goes up at a constant speed, your apparent weight will be the same as if it weren't moving.
What is apparent weight?
Apparent weight of an object is the weight of an object when the object is partially or totally immersed in a fluid{liquid/gas} normally apparent weight of an object is less than the real weight of an object due to an upward force {upthrust} which is produced by the pressure difference inside the fluids.
What the apparent weight if the lift moves downward with constant speed?
If you are in a lift (elevator) moving at constant speed, whether up or down, and you have no visual contact with the outside, then you don't know that the lift is moving, and no physical experiment can detect the motion. Your apparent weight is the same as when you're at 'rest'.
Elevator counter weight?
The suitable weight for an elevator counterweight is equal to the weight of the elevator itself. This ensures that the elevator moves smoothly and safely without any jerking or swaying. ESCON Elevators use high-quality counterweights that are perfectly balanced, ensuring a smooth and comfortable ride for every passenger.
How do you draw an elevator free body diagram?
Draw an arrow pointing upwards for the tension force and an arrow pointing downwards for the weight of the elevator which will be its mass times gravity (mg). Also, draw another arrow pointing downwards for any mass that may be inside the elevator (another mass times gravity arrow but for a separate weight) and add that value to that of the weight of the elevator. Depending on the direction that the elevator is moving (up or down) draw another arrow respectively and label it "a" for acceleration.
What is apparent weight how the apparent weight is different for different condition?
Apparent Weight is the weight of an Object in a SPECIFIC Gravitational condition, such as on Earth. The same object on the Moon would have a different (Lesser) Apparent Weight. The only constant is the Mass of the Object in both of those locations.
If the apparent weight of an object can be found by subtracting the buoyant force from the weight of the object what is the apparent weight of the floating object?
Zero.
You are standing on a scale in an elevator Suddenly you notice your weight decreases What do you conclude?
The elevator is accelerating downwards.
If I am in an elevator that is traveling upward at constant speed How does weight compare to your normal weight on the ground?
If the elevator's speed is constant (acceleration is zero), regardless of whether it's up or down,then your weight in it is the same as your normal weight on the ground.It should be easy to carry a bathroom scale onto an elevator with you some day and check it out.
What is the maximum weight on a dover elevator?
1200 pounds
