Homework Help Overview

The discussion revolves around calculating the energy stored in a spring based on a force-extension graph, specifically when a force of 12N is applied, resulting in an extension of 80mm. The participants are exploring the relationship between force, extension, and energy in the context of spring mechanics.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the linear relationship in the force-extension graph and question what the area under the graph represents. There is uncertainty about the implications of this area in terms of energy.

Discussion Status

The discussion is active, with participants questioning and clarifying concepts related to the area under the graph and its relation to energy. Some guidance has been provided regarding the interpretation of the area as energy, but there is still uncertainty about the calculation process.

Contextual Notes

Participants express a lack of confidence in their understanding of the topic, indicating that the exam is imminent and that they are seeking clarification on fundamental concepts.

1. Calculate the energy stored in the spring when a forceo f 12N is applied (revision
a graph is given (force extension graph and when the force is 12N, the extension is 80mm)




2. f=kx



3. I do not know how to solve this problem and my exam is tomorrow!

In the graph of F against x, the force should vary linearly. What does the area under the graph give?
 
k, the spring constant?

No, the area under the graph would give the product of a force and a distance, which is what?

is it Newton Metres?
I genuinely am unsure on this topic to be honest

Yes Nm, which is also the same as Joule, which is energy. So what does the area give?

does it give the energy stored in joules?

so i have to calculate the area under the graph from 12N downward?
