Spring Scale Flashcard

Front

What is a spring scale?

Back

A spring scale is a device used to measure weight by the distance a spring stretches or compresses under the load.

Front

How does a spring scale measure weight?

Back

A spring scale measures weight by stretching a spring; the amount of stretch is proportional to the weight of the object.

Front

What is the primary use of spring scales in commercial settings?

Back

Spring scales are primarily used in restaurants, cafeterias, and grocery stores to measure weight.

Front

What is the difference between weight and mass?

Back

Weight is the force exerted by gravity on an object, while mass is the amount of matter in an object, independent of gravity.

Front

What units are commonly used to measure weight with a spring scale?

Back

Common units include grams (g), kilograms (kg), and pounds (lbs).

Front

What is Hooke's Law?

Back

Hooke's Law states that the force exerted by a spring is directly proportional to the distance it is stretched or compressed.

Front

What factors can affect the accuracy of a spring scale?

Back

Factors include the calibration of the scale, the condition of the spring, and external environmental conditions.

Front

What is the relationship between force and weight?

Back

Weight is a specific type of force that results from the gravitational pull on an object's mass.

Front

How can you convert weight measured in pounds to kilograms?

Back

To convert pounds to kilograms, multiply the weight in pounds by 0.453592.

Front

What is the significance of zeroing a spring scale?

Back

Zeroing a spring scale ensures that it reads zero when no weight is applied, allowing for accurate measurements.
