Is the act of gaining mass considered a 'motion'?

In summary, the conversation discusses the concept of gaining mass and whether it can be considered a form of motion. The individual mentions the property of inertia and its role in motion, but it is determined that the question does not pertain to physics. Instead, it is suggested that the question pertains to social sciences or biology. The individual also brings up the idea of habits and its impact on weight and health, but it is noted that this is not a serious premise. Ultimately, the only relevant physics explanation is the relationship between calorie intake and weight gain.

say a guy is eating and gains mass
does this act of gaining or losing mass considered a motion?

i know mass has a property called 'inertia' (or is it the other way around where inertia has the property of mass?)
and inertia is the 'resistance' to motion or change in state of motion

but i don't think I'm talking about inertia here...

what sparked this question?...
its just that fat people tend to stay fat
and people that stay healthy tend to stay healthy
what I'm saying is habits, that people tend to continue to do what they've always been doing
aka
Newton's First Law:

"An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force."

thanks

Some people get fat because they don't move, or move enough.

what sparked this question?...
its just that fat people tend to stay fat
and people that stay healthy tend to stay healthy

But, in the end, everybody dies anyway.

Because that question isn't about physics. Look at the title at the top of the page. It says Physics Forums. Questions that are not about physics have a tendency to remain unanswered around here.

then what kind of question is this?

someone rephrase this: is the act of gaining mass considered a 'motion'? into a "physics" question please, because apparently I'm too stupid to be in this forum...

You are just trying to push an irrelevant analogy.
Newton's laws does not apply to people's habits.
But if you want to consider getting fat as a kind of motion, go ahead. What else is to it?

By the way, your premises are not really serious.
"people that stay healthy tend to stay healthy" ?

In order to gain mass, motion must be involved, otherwise objects with mass wouldn't come together to form a larger, more massive object.

Your original question is extremely confusing and involves things that don't fall under physics; IE people's eating habits and other behaviors. That is a social sciences/biology issue. There are many, many reasons people become and remain overweight. The only real physics explanation that applies here is that they don't burn more calories than they take in, which is what is required to lose weight.

The relationship between the original question and physics has been explained. Continuing to use a bad analogy is not going to take us anywhere we want to be.
 

FAQ: Is the act of gaining mass considered a 'motion'?

1. Is gaining mass considered a form of motion?

No, gaining mass is not considered a form of motion. Motion refers to the movement of an object from one place to another, while gaining mass refers to an increase in the amount of matter an object contains.

2. Can gaining muscle mass be considered a type of motion?

No, gaining muscle mass is not considered a type of motion. While it may involve physical movement and changes in the body, it is not the same as the motion of an object.

3. Is gaining weight considered a form of motion?

No, gaining weight is not considered a form of motion. Weight refers to the force of gravity on an object, while motion refers to the movement of an object.

4. Can gaining mass be compared to the motion of an object?

No, gaining mass cannot be directly compared to the motion of an object. While both involve changes in physical properties, they are distinct concepts with different definitions.

5. How does gaining mass affect an object's motion?

Gaining mass can affect an object's motion by changing its inertia, or resistance to changes in motion. A heavier object will have more inertia, making it more difficult to move or change its motion compared to a lighter object.
