Energy possessed by a body by virtue of its position or configuration is ______.
potential energy
nuclear energy
electromagnetic energy
kinetic energy
potential energy
Potential energy is the stored energy possessed by a body due to its position, state, or configuration. Common examples include gravitational potential energy (mgh) and elastic potential energy stored in a stretched or compressed spring (21тАЛkx2).

A wound-up spring in a toy car stores mechanical energy because of its coiled configuration; when released, it moves the car.
P for Position/Configuration тЖТ Potential Energy.
PE=mgh тАФ Gravitational Potential Energy
PE=21тАЛkx2 тАФ Elastic Potential Energy of a Spring
When work is done on a body against a conservative force (like gravity or a spring force) without producing any kinetic energy change, the energy is stored within the system as potential energy. This energy can later be converted back into kinetic energy when the configuration or position of the body changes.
Potential energy is relative to a chosen reference level (zero potential energy surface).
It is a scalar quantity measured in Joules (J).
Forces associated with potential energy are conservative forces (e.g., gravity, spring force).
Can be stored and later converted completely into useful mechanical work or kinetic energy.
Depends on the choice of reference frame (position coordinates).
Water stored behind a hydroelectric dam.
A stretched bow and arrow before release.
A pendulum at its highest point of swing.
Kinetic energy is the energy possessed by a body due to its motion (KE=21тАЛmv2).
Nuclear energy is stored within the nucleus of an atom due to strong nuclear forces.
A is correct тАФ Potential energy is the energy possessed by a body by virtue of its position or configuration.
Remember that conservative forces are negative gradients of potential energy: F=тИТdxdUтАЛ, a frequent concept in Indian engineering entrance exams like RRB, SSC, and JEE.
