Talk:Mass

message: I made a change to the story about mass. it said for anyone who couldn't really get how you first put mass : "to put it simply, mass is how much stuff something has." after a little while, it said that my " violation " was unnecessary and I got blocked from making further edits. All i'm saying is that maybe people should check if the person or robot is doing it's job correctly.  — Preceding unsigned comment added by 70.114.188.53 (talk) 19:25, 13 October 2018 (UTC)

message: The image of a 2kg weight is labeled incorectly. The weight has a MASS of 2kg and a weight of about 19.62 N - this is important as mass and weight are two different concepts.  — Preceding unsigned comment added by Mikeymat (talk • contribs) 17:31, 31 March 2019 (UTC)

message: Hey guys, the redefinition of 1 kilogram has been done and Wikipedia has an article for this. Kindly update the page as it says that the redefinition is expected on may 20, 2019. Thanks. clickheretogototheuserpageofAggarwala2727 (talk) 07:16, 21 September 2019 (UTC)

message: New to this semi-protected articles so I hope I'm doing this correctly
I was hoping to add an illustrative example to the definitions section on energy-mass equivalence. 
Original paragraph:
Energy also has mass according to the principle of mass–energy equivalence. This equivalence is exemplified in a large number of physical processes including pair production, nuclear fusion, and the gravitational bending of light. Pair production and nuclear fusion are processes in which measurable amounts of mass are converted to energy, or vice versa. In the gravitational bending of light, photons of pure energy are shown to exhibit a behavior similar to passive gravitational mass.
Suggested change in context:
Energy also has mass according to the principle of mass–energy equivalence. This equivalence is exemplified in a large number of physical processes including pair production, nuclear fusion, and the gravitational bending of light. Pair production and nuclear fusion are processes in which measurable amounts of mass are converted to energy, or vice versa. In the gravitational bending of light, photons of pure energy are shown to exhibit a behavior similar to passive gravitational mass. The majority of the mass of a proton is from constituent quark, not simply the mass of its quarks.

thread_title:  In energy-mass equivalence definition suggest adding example of proton's mass being mostly gluon energy 

message: The first sentence in this section states: "In physical science, one may distinguish conceptually between at least seven different aspects of mass, or seven physical notions that involve the concept of mass.", which brings the expectation of 7 physical notations, while the following bullet points ("number of ways mass can be measured or operationally defined") are only 6 (six).
Either these two topics of "physical notions" and "ways of measurement / operational definition" are different from each other, or there is an unintentional distraction caused. If they are different, shouldn't those 7 physical notions be listed as well to avoid confusion? Can someone clarify it? --Mojtaba Mohammadi (talk) 11:58, 20 January 2022 (UTC)
