Question

A. E = 0.5 x k x e^2 — calculation focus for energy store
B. This confuses elastic and plastic deformation and does not answer Elastic potential energy.
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: E = 0.5 x k x e^2 — calculation focus for energy store

Explanation

The correct option is E = 0.5 x k x e^2 — calculation focus for energy store. E = 0.5 x k x e^2 — calculation focus for energy store is correct because it matches the approved learning objective to describe elastic potential energy as energy stored in a stretched or compressed elastic object. This answer belongs to Elastic potential energy 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

Misunderstanding Elastic Potential Energy

Students often confuse elastic potential energy with the total energy of the object, not recognizing it as the energy stored specifically in a stretched or compressed elastic object.

Emphasize that elastic potential energy is only the energy stored due to deformation and is distinct from other forms of energy the object may possess.
