The discussion revolves around the concept of inertia in relation to mass and velocity. The original poster presents a scenario with specific values for velocity and mass, seeking to determine inertia. There is confusion regarding the relationship between inertia and momentum, as well as the appropriate calculations to use.
The conversation is ongoing, with participants providing guidance on the need for clarity in the problem statement. The original poster has indicated a shift in understanding, realizing that the question was about ordering masses based on inertia rather than calculating it directly.
There is mention of a template that should be filled out for homework submissions, and the original poster acknowledges a misunderstanding of the question's requirements. The discussion reflects confusion around the definitions and applications of inertia and momentum.
Note that you need to fill out the entire template and show what you've tried in order to solve the problem, or at least explain your understanding of it so far. Helpers are not permitted to offer any guidance otherwise.Megan1000 said:Homework Statement
v=2m/s
m=10kg
find the inertia
at first i did 2m/s times by 10kg which is 20 but i also did 2 divided by 10 =0.2 and 10 divided by 2= 5 but I'm unsure which method is correct.gneill said:Hi Megan1000,

Can you explain what you mean by "inertia"? Is it a term that is defined in your course notes or course textbook? Perhaps you meant "momentum"?
so what should i use instead then?scottdave said:Inertia is this property, which is talked about, but rarely used in calculations (except when referring to Moment of Inertia, for objects which rotate).
Being that inertia is resistance to change in motion, the closest thing to inertia, is the mass of the object.
If you meant something different, then please clarify the problem statement.
