What else can I help you with?
What if your mass is 75kg. You stand on a scale in an elevator that is about to go down. Starting from rest the elevator accelerates at 2.0ms squared for 2.0s then travels at a constant speed. What do?
While the elevator accelerates downward, you will experience a greater force than your actual weight, resulting in a higher reading on the scale. Once the elevator reaches a constant speed, the scale will show your actual weight, as the net force on you is then equal to your weight.
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 are the advantages and of spring balance?
Advantages: lighter, more compact, and easier to use. Weighing capacity tends to be bigger. Disadvantages: with repeated use, the spring in the scale can be permanently stretched. This tends to bring less accurate weights.
Does a scale show weight or mass?
It shows the weight, however, by convention we graduate the scale in mass units. The scale is assuming that you are standing on Earth. When you step on a scale the gravity pulls you down, which is called weight. Weight is based on the gravity force. Mass is the amount of stuff inside your body. Which won't change because of gravity. If you go to the moon your weight will be less because the moon has less gravity. Mass will stay the same. Unless you lose one your body parts while on the trip to the moon.
If your standing on a scale and push down on a sink next to you how does the reading on the scale chage?
The number will lower because you are lifting yourself up, thus causing the number on the scale to go down. The force of you pushing on the sink is the counter force to the gravitational force of your body. This means your putting force on the sink and going up. Hope I helped! ;)

What is one rule you should know when using a spring scale?
one very important spring scale rule is never go past the limit of newtons it can go up to.
Does a spring scale measure weight?
A spring scale is any device that uses the translation of a spring by force due to weight to discover the mass of an object. Let's translate that into easier words. A spring wants to hold its shape. But it is elastic, and if we apply a force to it, it changes shape. The amount of change in its shape will be proportional to the force applied to it. That's Hooke's law of elasticity. Nothing could be simpler. How does that apply? Jump with me and we'll see. By attaching a pointer or dial to a spring in a particular way, we can use the "coefficient of elasticity" of the spring to tell us how much gravity is pulling on something (which is force). We use that something to change the shape of the spring, and by indexing the movement of that spring, that is, setting up a scale or dial, we can use the device (after calibration) to give us a fairly accurate measure of the weight of an object. Most of us are familiar with the spring scale as the so-call "bathroom scale" which is kept secreted away in the water closet. It's a spring scale, and a useful device (though there seem to be more and more electronic interlopers). There are also small versions of the spring scale, too. We find them in home kitchens for weighing food or small objects, as well as in some fishing tackle boxes. Before the electronic age, these little scales were everywhere that there was commerce. Think of all the stuff that gets weighed from meat and produce at the store to the letters and packages at the mailing places. The spring scale used to do all that. And it did it pretty well, too. Links are provided to Wikipedia articles for further reading. A device used to determine the weight of an object (usually fairly light like 10 pounds or less). It uses a spring attached to a hook to work. The object to be weighed is hung from the hook, which compresses the spring. The amount that the spring is compressed is read on a scale that is graduated in pounds.

How does the elevator work?
Passenger elevators are big pulleys powered by a motor with 6-8 cables or more that pull the elevator cab or the counter weight letting the elevator go up or down.
What is the best travel scale for accurately measuring body weight on the go?
The best travel scale for accurately measuring body weight on the go is the Etekcity Digital Body Weight Bathroom Scale. It is compact, lightweight, and provides precise measurements, making it ideal for travel.
A laboratory equipment used for measuring the weight.?
A laboratory balance is used to measure the weight of substances accurately. It consists of a platform for the object to be weighed and the balance mechanism that registers the weight. The balances come in various types, such as analytical balances for precise measurements and top-loading balances for general weighing.
How do you figure axel weight on a semi truck?
Well, you either go to a CAT scale, which weighs each groups of axles separately, or, if you're on a scale which only shows gross weight, then you axle out. You drive onto the scale and stop with only your steer axle on the scale. Then you write down that weight, and pull forward until your drive and steer axles are both on the scale. Then you write down that weight, and subtract the weight of your steer axle to get the weight on your drive axles. Then you pull forward until all axles are on the scale. This will be your gross weight, and you subtract the weight you got when you had the drive and steer axles on the scale in order to get the weight on your trailer axles.
How can I accurately measure my body weight on-the-go with a portable scale?
To accurately measure your body weight on-the-go with a portable scale, make sure to place the scale on a flat, stable surface. Step on the scale with both feet and wait for the reading to stabilize. Ensure that the scale is calibrated properly and use it consistently at the same time each day for more accurate results.
Where can I find a weight chart for the suggested weight for my height?
Go to www.healthchecksystems.com/heightweightchart.htm for a height and weight chart that will help you figure out where you're at on the recommended scale.
How does elevators work?
Passenger elevators are big pulleys powered by a motor with 6-8 cables or more that pull the elevator cab or the counter weight letting the elevator go up or down.
