Which Statements About Mass & Weight are True?

In summary, the conversation discusses the differences between mass and weight, and the relationship between the two on Earth and the moon. The general consensus is that mass and weight are not the same thing, with mass being a measure of an object's intrinsic property and weight being the force of gravity acting upon an object. It is also clear that the mass of an object will remain the same on Earth and the moon, but its weight will vary due to the difference in gravity. Additionally, it is noted that objects have weight even in a vacuum and more massive objects will weigh more than less massive objects.

The problem is that unless you show you have tried to answer these questions yourself, it's not likely that anyone is going to help. You can't just post questions with the expectation that the answers will be given to you.

I suggest that you study the differences between mass and weight and then try to answer the questions yourself. Post your answers and explain how you arrived at your conclusions.

Hint:

Force = mass * acceleration

badboyben03, use that answer at your own risk...

badboyben03:
First, please do not post the same question under different section.

Second, read "Read this first" posted at the head of the homework section. It doesn't help you to have someone do your homework for you. Show us what you have tried.

Third, these should be obvious if you know the definitions of "mass" and "weight". What are the definitions in your textbook?
 

1. What is the difference between mass and weight?

The main difference between mass and weight is that mass is a measurement of the amount of matter in an object, while weight is a measurement of the force of gravity on an object. Mass is measured in kilograms (kg), while weight is measured in newtons (N).

2. Are mass and weight interchangeable?

No, mass and weight are not interchangeable. Mass is an intrinsic property of an object and does not change depending on the location or environment, while weight can change based on the strength of gravity.

3. Can an object have zero mass but still have weight?

No, an object cannot have zero mass but still have weight. Weight is directly proportional to mass, so if an object has zero mass, it also has zero weight.

4. Is weight a reliable way to measure an object's mass?

No, weight is not a reliable way to measure an object's mass. Weight can be affected by the strength of gravity, while mass is a constant property of an object. In order to accurately measure an object's mass, a balance or scale should be used.

5. Do all objects have the same weight on Earth?

No, all objects do not have the same weight on Earth. Weight is affected by the strength of gravity, so objects with different masses will have different weights on Earth. However, all objects with the same mass will have the same weight on Earth.
