In plain English: Kinetic describes something that is related to motion or energy of movement.
"The kinetic energy from his running footstep kicked up dust on the floor."
Usage: This adjective describes motion rather than the state of being fluid; use it to characterize moving objects or energy, not liquids themselves. Avoid confusing it with "kinetic" as a noun, which is incorrect usage.
The word kinetic comes from the Ancient Greek kinētikós, which literally meant "that puts things into motion." It entered English to describe anything related to movement or energy.
