Question 1:

What is a spring scale used for?

A) Measuring temperature
B) Weighing heavy objects
C) Determining the mass of an object
D) Measuring force or weight

Show Answer

Explanation: The correct answer is D) Measuring force or weight. A spring scale is a device used for measuring force or weight. It utilizes the principle of Hooke's Law, where the extension of a spring is proportional to the applied force, to provide a measurement of the force or weight being applied to it.

Question 2:

How does a spring scale work?

A) By measuring the elongation or compression of a spring
B) By utilizing a balance beam and weights
C) By measuring the density of an object
D) By measuring the temperature of an object

Show Answer

Explanation: The correct answer is A) By measuring the elongation or compression of a spring. A spring scale works by measuring the deformation of a spring due to the force applied to it. As the force increases, the spring elongates or compresses, and this change is translated into a weight or force measurement displayed on the scale.

Question 3:

What unit of measurement is commonly used by spring scales?

A) Pounds (lb)
B) Kilograms (kg)
C) Newtons (N)
D) Ounces (oz)

Show Answer

Explanation: The correct answer is C) Newtons (N). Spring scales commonly measure force or weight in Newtons (N). However, some spring scales may also provide measurements in other units such as pounds (lb) or kilograms (kg) for convenience or compatibility with different regions.

Question 4:

What is the main advantage of using a spring scale?

A) High accuracy and precision
B) Low cost and simplicity
C) Large weighing capacity
D) Digital display for easy reading

Show Answer

Explanation: The correct answer is B) Low cost and simplicity. One of the main advantages of using a spring scale is its low cost and simplicity. Spring scales are relatively inexpensive compared to other types of scales, and their simple design makes them easy to use without requiring complex calibration or power sources.

Question 5:

What should be done before using a spring scale for measurement?

A) Expose the scale to extreme temperatures
B) Calibrate the scale using known weights
C) Use excessive force to test the scale's capacity
D) Place the scale on an inclined surface

Show Answer

Explanation: The correct answer is B) Calibrate the scale using known weights. It is important to calibrate a spring scale using known weights before use. This helps ensure accurate and reliable measurements by adjusting the scale to account for any variations or deviations. Calibrating with known weights helps verify the accuracy of the spring scale and maintain its performance over time.
