Question

A. The change in shape that is fully reversed when the force is removed — definition focus for elastic deformation
B. This confuses elastic and plastic deformation and does not answer Stretching and deformation.
C. This is too vague because it does not use the force or motion quantity named in the objective.
D. This reverses the physical cause and effect for Forces and elasticity.

Answer

The correct answer is: The change in shape that is fully reversed when the force is removed — definition focus for elastic deformation

Explanation

The correct option is The change in shape that is fully reversed when the force is removed — definition focus for elastic deformation. The change in shape that is fully reversed when the force is removed — definition focus for elastic deformation is correct because it matches the approved learning objective to define elastic deformation as deformation that is reversed when the force is removed. This answer belongs to Stretching and deformation within Forces and elasticity, so it must use precise AQA GCSE Physics forces and motion vocabulary. The other options are wrong because they either confuse elastic and plastic deformation, omit the required force or motion condition, or move away from the exact subtopic being tested.

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.
