Mechanical Energy is described as

• A. The energy of electric charges
• B. Energy stored in the nucleus of an atom
• C. Energy carried by light
• D. Kinetic or potential energy associated with motion or position of an object

Answer: (D)

Mechanical energy is the energy tied to an object's motion and its position in a mechanical sense. It includes two parts: kinetic energy, which depends on speed (1/2 m v^2), and potential energy, which depends on height or deformation in a mechanical field (like gravity giving m g h or an stretched/compressed spring giving elastic potential energy). In a frictionless system, the total mechanical energy stays constant because energy simply shifts between kinetic and potential forms as the object moves. The other options describe different types of energy not tied to the motion or position of a macroscopic object in a mechanical sense: electrical energy relates to electric charges and fields, nuclear energy to forces within the atomic nucleus, and radiant energy to light and electromagnetic waves.
