Which one is heavier and why?

  • Thread starter DrChem

In summary, weight is a measurement of the force of gravity on an object, typically measured in units of mass. The difference between weight and mass is that while weight can change depending on the strength of gravity, mass is constant. The object with a greater mass will be heavier because it has a greater amount of matter. Weight is affected by location and environment, as the strength of gravity can vary and factors such as air resistance can also play a role. To determine which object is heavier, you can compare their masses or use a scale to measure their weight.

you have a bag of cotton and an iron bar, each indicating a mass of 100 kg when measured on a weighing machine. in reality, one is heavier than the other. can you say which one is heavier and why?

Is there an atmosphere permeating the weighing machine?

"can you say which one is heavier and why? "

If I were using a NIST traceable weighing machine, I'd use the standard correction for the effect you're thinking of and neither would be heavier.
 

1. What is weight?

Weight is a measurement of the force of gravity on an object. It is typically measured in units of mass, such as kilograms or pounds.

2. What is the difference between weight and mass?

While weight is a measurement of the force of gravity on an object, mass is a measure of the amount of matter an object contains. Mass is constant and does not change, whereas weight can vary depending on the strength of gravity.

3. Which one is heavier and why?

The object with a greater mass will be heavier. This is because the greater mass will have a greater amount of matter, resulting in a greater force of gravity acting on it.

4. Is weight affected by the location or environment?

Yes, weight is affected by the location or environment. The strength of gravity can vary depending on the location, such as on different planets or at different altitudes. Additionally, factors such as air resistance can also affect weight.

5. How can I determine which object is heavier?

You can determine which object is heavier by comparing their masses. The object with the greater mass will be heavier. You can also use a scale to measure the weight of each object, as weight is a direct measurement of the force of gravity on an object.
