The area of force versus displacement graph is
Correct answer: D. Work done
- A. Young's modulus
- B. Spring constant
- C. Elasticity
- D. Work done
Explanation
The correct answer is Work done. The area under a force versus displacement graph represents the work done on an object, as work is calculated by integrating force over displacement. This is a key concept in mechanics, where the work-energy principle states that the work done by forces on an object results in a change in the object's kinetic energy. Young's modulus, the spring constant, and elasticity are related to material properties and mechanical characteristics, but they do not describe the area under the force-displacement curve.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
