The correct answer is D) The energy a body possesses due to its position. Potential energy is the energy a body possesses due to its position or configuration within a force field, such as gravity. It is the energy a body has by virtue of its position, which can be converted to kinetic energy through movement. This is in contrast to kinetic energy, which is the energy a body possesses due to its motion. The other answer choices are incorrect because: A) Kinetic energy, not potential energy, is the energy a body possesses due to its motion. B) Potential energy is not measured in feet per second, but rather in units of energy like joules. C) Potential energy is not a measurement of total pressure.
