Question
How can you determine the spring constant from a force-extension graph?
Answer
The spring constant can be determined by calculating the gradient of the linear section of a force-extension graph, where the gradient represents the ratio of force to extension.
Explanation
This answer is strong as it explains the method to find the spring constant using graphical analysis, which is a key skill in physics. The question assesses the student's ability to apply knowledge of graphs to real-world scenarios.
Common mistake
Misunderstanding Hooke's Law
Students often confuse the relationship in Hooke's Law, thinking that force and extension are not directly proportional beyond the limit of proportionality.
To fix this, students should practice identifying the limit of proportionality on force-extension graphs and understand that Hooke's Law applies only within this limit.
