Hello there, I was not sure if this belonged in the Classical Physics forum or the General Physics forum, so my apologies if it's in the wrong place. This topic is part physics and part linguistics. An acquaintance (someone who has never studied beyond basic high school physics) recently use the terms 'kinetic movement' and 'kinetic motion'. It sounded odd, and somewhat redundant. Kinematics is the study of motion, after all. It's kind of like saying 'big giant' or 'funny joker'. Not only that, but 'kinetic' used as an adjective for movement also sounds odd. It is the adjective form of the noun 'kinesis' which literally means motion/movement. The common use for kinetic is 'kinetic energy', or energy that is the result of motion, and not the other way around. I'm not an expert of either physics or the English language, so I was hoping someone on this forum would have some insightful words on the subject.
