You may not think you need it but you have it regardless of what you think you need. Can you not understand that energy is inherently tied to objects in motion?

This is the same thing all over. If I have a temperature and a wind speed you have a wind chill factor. Wind chill is the rate of cooling relative to still air. You can't have a cold windy day without a wind chill factor. Just like energy of a moving object it is there and known.
