Homework Help Overview
The discussion revolves around understanding the behavior of an oscillating graph in the context of a mass-spring system, specifically examining why the graph appears to be decreasing. The subject area includes concepts from mechanics, particularly oscillations and Hooke's law.
Discussion Character
- Exploratory, Conceptual clarification, Mathematical reasoning
Approaches and Questions Raised
- Participants explore the relationship between velocity, displacement, and force in oscillatory motion. There are attempts to apply Hooke's law and questions about the implications of displacement on force.
Discussion Status
Participants have engaged in clarifying the relevant equations and concepts, particularly Hooke's law. There is an ongoing exploration of how these concepts relate to the observed behavior of the graph, with some guidance provided on plotting force versus time.
Contextual Notes
There is a mention of a potential typo in the equations presented, indicating a need for careful attention to detail in the mathematical expressions used in the discussion.

Welcome to the PF.
No, the answer is not E. Think in terms of forces. What is the Relevant Equation that relates the spring force on the mass to the displacement of the mass from the uncompressed position of the spring...?

Yep, good. So write out Hooke's law for this problem. If the graph shows the displacement versus time of the mass, can you plot the Force versus time on the same time axis? What is the force when the displacement is zero?

F= -kX
So
F= -(A)(T)
So thuis mean - and 0 so C?
So
F= -(A)(T)

Yep, good! That's why we have the section of the Homework Help Template that asks for the Relevant Equations. Often just by listing the equations that are involved, it makes figuring out the problem much easier. :-)

Actually, one small typo fix -- you correctly show F=-kx, but then you say F=-AT. It should be F=-A*0 = 0. But I think that's what you meant anyway.
