Question
What is extension in the context of stretching an object?
Answer
Extension is defined as the increase in length of an object when it is subjected to a stretching force. It is measured as the difference between the original length and the new length after the force is applied.
Explanation
This answer is strong because it clearly defines extension and explains how it is measured, which is essential for understanding the concept in physics. The question tests the student's ability to recall and articulate the definition of extension.
Common mistake
Misunderstanding Extension
Students often confuse extension with total length, thinking that extension is the final length of the object after stretching.
Extension should be defined as the increase in length from the original length, so students should practice calculating extension by subtracting the original length from the new length.
