Question
What is the definition of extension in the context of elastic materials?
Answer
Extension is defined as the increase in length of an elastic object when a stretching force is applied. It is measured as the difference between the original length and the new length of the object.
Explanation
This question tests the student's understanding of the concept of extension, which is fundamental in the study of elasticity and Hooke's law. A clear definition demonstrates comprehension of how materials respond to forces.
Common mistake
Common Mistake in Elastic Potential Energy Calculations
Students often confuse extension in the elastic potential energy equation, using incorrect units such as centimeters instead of meters.
Always convert extension to meters before substituting into the elastic potential energy equation.
