Spring Scale Practice

Front

What is a spring scale?

Back

A spring scale is a device used to measure the weight or force exerted on an object, typically using a spring that stretches in response to the force.

Front

What unit is commonly used to measure weight in physics?

Back

The Newton (N) is the standard unit of force in the International System of Units (SI).

Front

How do you convert grams to Newtons?

Back

To convert grams to Newtons, divide the mass in grams by 1000 and multiply by the acceleration due to gravity (approximately 9.81 m/s²).

Front

What is the maximum weight a spring scale can measure if it is rated for 5 Newtons?

Back

The maximum weight is 5 Newtons, which is equivalent to approximately 500 grams.

Front

If an object weighs 2.4 N, what is its mass in grams?

Back

The mass is approximately 245 grams (2.4 N / 9.81 m/s² * 1000).

Front

What does it mean if a spring scale reads 0 N?

Back

A reading of 0 N indicates that there is no force acting on the scale, meaning the object is either not present or in a state of free fall.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object's mass. It is calculated as Weight = Mass × Gravity.

Front

How can you determine the weight of an object using a spring scale?

Back

Hang the object from the spring scale and read the measurement directly from the scale, which indicates the weight in Newtons.

Front

What is the formula for calculating weight?

Back

Weight (W) = Mass (m) × Acceleration due to gravity (g).

If a spring scale measures 1.9 N, what is the equivalent weight in grams?

Back

The equivalent weight is approximately 194 grams (1.9 N / 9.81 m/s² * 1000).
