The correct answer is A because kinteic energy means movement, motion and the baseball is in catcher's glove is not moving is static, doesn't show motion
The right answer is A. a baseball in a catcher’s glove.
The other propositions all contain a verb testifying to the mobility of the subject.
Kinetic energy is the energy that a body possesses because of its movement. The kinetic energy of a body is equal to the work necessary to bring the body of rest to its movement. It can be deduced from this, in the context of Newtonian physics, that a variation of kinetic energy of a body for a certain duration is equal to the work of the external forces exerted on that body. This is the theorem of kinetic energy.
