Does a scale read more or less in an elevator that is accelerating upward?

It will increase! if the elevator is moving with a constant velocity, then there will be no change in the reading as no acc. will be caused. but if the body moves downwards wit a uniform acc. of say suppose x m/s^2, then the weight if the body will decrease by F=m x a(of the lift) as the two vectors will be in the opp direction, i.e. downwards. the opposite applies when the when the body acc. in an upward direction, the vectors will be in an same direction and it will result in the scale reading turing up more!
remmember, a sacle measures the upward force aka reaction force

Would the springs inside a bathroom scale be more compressed or less compressed if you weighed yourself in an elevator that moved upward at constant velocity?
While you're moving up or down at constant speed, the situation is exactly the same as standing on the ground. The scale reads your weight, and the springs are in the same condition as they are when the scale is on the floor of your bathroom. -- During the brief few seconds when you're accelerating downward ... starting down from an upper floor or stopping your ascent at an upper floor ... your weight temporarily seems to be decreased, and the springs are less compressed. -- During the brief few seconds when you're accelerating upward ... starting up from a low floor or stopping your descent at a low floor ... your weight temporarily seems to be increased, and the springs are more compressed.
Why do you weight less on the elevator?
You weigh less only while the elevator's upward speed is decreasing, or downward speed is increasing. In each case, the acceleration of the elevator is in a direction opposite to the acceleration of gravity. The result of that is that the total acceleration acting on you is less than usual, and your weight is less. Note that in a sealed container, such as a space ship or an elevator, there's no way for you to tell the difference between acceleration and a gravitational field.
When riding in an elevator why does a person appear to lose weight when accelerating downward?
Weight is felt by the body resisting the pull (acceleration) of gravity. Less acceleration means less pull thus less weight. The rate at which you are accelerating downward subtracts from the pull of gravity, thus your weight is less. If you fall, say from a cliff or tall building you accelerate downward at exactly the acceleration of gravity so you're completely weightless.
A ball is thrown upward and caught when it comes back down In the presence of air resistance the speed with which it is caught is?
less than the speed it had when thrown upward.
Why does a bubble grow and move faster as it ascends?
Atmospheric pressure at ground level is higher than at a greater altitude, therefore as the bubble rises the atmospheric pressure on it's surface decreases creating less of a squashing effect on the bubble, making it expand. The impetus for it's upward climb is that the warm air from your lungs is less dense and therefore is forced upwards by the cooler external air. As atmospheric pressure reduces at greater altitude the bubble becomes less dense, accelerating it's upward climb. The reduction in pressure decreases and the bubble continues to expand until it's molecular bonds become strained and the bubble bursts.

In an elevator when is your apparent weight less than your real weight?
When the lift is accelerating downwards. See related question.

Why do melts migrate upward?
Melts move upward because they are less dense than the solids.
Why did the chain-type bucket elevator replace the belt-type bucket elevator?
It was more reliable and required less maintenance.
What will the elevator be like in 10 years?
In aprox 10 years, the elevator will have evolved-like man did from chimp. It will move faster, have less breakdowns, cost less to install and be more electricity efficent. in conclusion, the elevator will be way more evolved in 10-15 yrs time
Do you have to pay to see the Eiffel tower?
No, but to climb on it, you do have to pay. The stairs are less expensive than the elevator, so I'd take them instead of the elevator.
A ball is thrown upward and caught when it comes back down In the presence of air resistance the speed with which it is caught is?
less than the speed it had when thrown upward.
What are areas of less dense warm air that can be forced upward?
Low pressure
What can you do to improve mpg Toyota hybrid?
Drive less aggressively, use the brakes less, keep steady speed without accelerating fast/frequently.
Why was the elevator invented?
because people needed to get to another floor of a building faster then usual. If you took the stairs it would have taken a long time. That is why Elisha Graves Otis invented the first elevator. Then soon after somebody improved it by making it an electrical elevator and that person was Werner Von Siemens. That is why they invented the elevator and the electrical elevator.
