Spring Scale Flashcard

Front

What is the purpose of zeroing the scale before using a spring scale?

Back

To measure weight accurately.

Front

How does a spring scale work?

Back

By stretching a spring.

Front

What is the unit of measurement typically used with a spring scale?

Back

Newtons (N) or pounds (lbs).

Front

What physical principle does a spring scale operate on?

Back

Hooke's Law, which states that the force exerted by a spring is proportional to its extension.

Front

What is the relationship between mass and weight?

Back

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

Front

How can you convert mass to weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g), where g is approximately 9.81 m/s² on Earth.

Front

What is the significance of the spring constant in a spring scale?

Back

The spring constant (k) determines how much the spring stretches under a given load.

Front

What happens if a spring scale is not zeroed before use?

Back

It will give inaccurate weight measurements.

Front

What is the maximum weight a spring scale can measure called?

Back

The scale's capacity or maximum load.

Front

What is the difference between a spring scale and a digital scale?

Back

A spring scale uses a mechanical spring to measure weight, while a digital scale uses electronic sensors.
