Suppose that a 50.0 kg woman were standing on a bathroom scale in this elevator car what would the scale read?

On the way up:
-Before the car started moving, it would read 490 newtons (110 pounds).
-When the car started moving up, the scale would read more, until the car achieved its normal upward speed.
-As long as the car maintained its steady normal speed, the scale would again read 490 newtons (110 pounds).
-As the car approached its destination level and began to slow down, the scale would read less, until the car stopped.
-When the car stopped, the scale reading would return to its normal 490 newtons (110 pounds).
On the way down:
-Before the car started moving, it would read 490 newtons (110 pounds).
-When the car started moving down, the scale would read less, until the car achieved its normal downward speed.
-As long as the car maintained its steady normal speed, the scale would again read 490 newtons (110 pounds).
-As the car approached its destination level and began to slow down, the scale would read more, until the car stopped.
-When the car stopped, the scale reading would return to its normal 490 newtons (110 pounds).

You are standing on a scale in an elevator Suddenly you notice your weight decreases What do you conclude?
The elevator is accelerating downwards.
What is the acceleration of an elevator if a student stands on bathroom scale in the elevator and the scales reads 836 newtons and the elevator is moving upward?
We have no way to calculate that, unless you also tell us either his mass, or else his weight on motionless ground, like when the scale is on the bathroom floor.
What is the weight in elevator with spring scale when it go up?
If the elevator is moving uniformly, the spring scale should record the same weight when it's going up as it does when it's standing still.If the elevator is accelerating (speeding up or slowing down), the spring scale will record a greater or lesser weight respectively.
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.
You weigh yourself when you are in a motionless elevator You weigh 100 lbs The elevator starts to move and you weigh 90lbs What is the acceleration of the elevator?
The elevator is accelerating downwards at g / 10 or ~3.2 ft/sec/sec (.98 m/sec/sec) note. the question shows that the weighing took place on a bathroom scale or a spring balance. If you used a beam balance or a steelyard you would always measure 100lbs.

What is the amount of gravity on the human body?
You can measure the amount of gravitational force being exerted on your body by standing on a bathroom scale and weighing yourself.

When standing on bathroom scale are you measure in mass or density?
Scales either measure mass, or weight - but they are callibrated to show mass (for example, kilograms).
What are the numbers on a bathroom scale?
The numbers on a bathroom scale represent the pounds that you weigh. Some scales are digital and do not have a dial that turns when you step on the scale.

What happens to the reading on the scale when the elevator stops moving?
after an initial acceleration period,the elevator continues to move up with a constant speed.
Are bathroom scales really accurate about a person s weight and if not then what can you use to measure your progress?
Bathroom scales are very accurate. The same scale will show the correct reading day after day, no matter what. There is no better way to measure progress than using a bathroom scale. If the scale reads "120" the first week and "120" the second week the weight standing on it is exactly the same both weeks. It will be correct every time it is used. Doctors scales, on the other hand are very bad because they get used so much (10 or twenty times Every day), so the doctors scale will not give the same number as your bathroom scale. Trust your scale what is says is what it is.
How do you check accuracy of bathroom scale?
There are many bathroom scales nowadays that are claiming to be accurate. Some of these bathroom scales have gone digital. One way to check that your bathroom scale is giving you accurate results is to calibrate it so that you will know that your bathroom scale is definitely accurate. Try weighing something that you know the exact weight of. For example, weigh 10kilos of sugar or flour on the bathroom scale and check if it gives the exact result of 10kilos. If it does, then it is definitely accurate. But it if it gives you far off result, then the bathroom scale isn't worth it.
