What does kinetic energy mean in Greek?

Kinetic energy does not have a Greek origin, its etymology is Greek-Latin.

The term "kinetic" comes from the Greek word "kinetikos," which means "moving" or "pertaining to motion." The term "energy" is derived from the Greek word "energeia," which means "activity" or "work."

So, "kinetic energy" literally means "energy of motion" or "energy associated with the movement of objects."
