What are the advantages and disadvantages of using a spring scale to measure weight?

What are the advantages and disadvantages of using a spring scale to measure weight? For this lab in particular, a disadvantage is that some of these objects are not made to hook onto a spring scale, thus skewing the results. An advantage would be the accuracy of a spring scale, when used correctly.

What is the use of spring balance?

Main uses of spring balances are to weigh heavy loads such as trucks, storage silos, and material carried on a conveyor belt. They are also common in science education as basic accelerators. They are used when the accuracy afforded by other types of scales can be sacrificed for simplicity, cheapness, and robustness.

What is the accuracy of spring balance?

18.2. Because the characteristics of the spring are very susceptible to environmental changes, measurement accuracy is usually relatively poor. However, if compensation is made for the changes in spring characteristics, then a measurement inaccuracy less than ±0.2% is achievable.

What is the cost of spring balance?

Where are the sources of uncertainty when using a ruler and caliper?

3. What are the sources of uncertainty when using a ruler and caliper? The smallest graduations on a ruler is 0.1 cm and so taking the half least count in an uncertainty you get (+/-) 0.05cm. The smallest graduations on a caliper is .

Where does the force causing this vertical acceleration come?

A projectile is an object upon which the only force is gravity. Gravity acts to influence the vertical motion of the projectile, thus causing a vertical acceleration. The horizontal motion of the projectile is the result of the tendency of any object in motion to remain in motion at constant velocity.

What is the least count of a spring balance?

The least count can be determined by measuring a 1kg object and by counting the number of divisions that the needle is pointing upon when the weight is applied, which will be equal to 10 divisions. So we get the least count as 0.1kg per division or 100g per division.

Why do we calculate uncertainty?

Measurement uncertainty is critical to risk assessment and decision making. Organizations make decisions every day based on reports containing quantitative measurement data. If measurement results are not accurate, then decision risks increase. Selecting the wrong laboratory, could result in medical misdiagnosis.

Why is a caliper more precise than a ruler?

The caliper always give a more precise and accurate reading and you can use one more decimal place because of how exact the measurements are laid out. Accuracy is how close the measurement is to the true value, and because you can measure to a smaller measurement the readings are more exact.
