Question
Give an example of a material that exhibits elastic deformation and explain why it is classified as such.
Answer
Rubber is an example of a material that exhibits elastic deformation because it can stretch when a force is applied and return to its original shape once the force is removed.
Explanation
This answer provides a specific example and explains the reversible nature of the deformation, demonstrating an understanding of the concept. The question tests the student's ability to apply their knowledge to real-world materials.
Common mistake
Confusing Elastic and Inelastic Deformation
Students often confuse elastic deformation with inelastic deformation, thinking that all deformations can be reversed.
Remember that elastic deformation is when the object returns to its original shape after the force is removed, while inelastic deformation does not fully reverse.
