Wayne, you misunderstand what horsepower is. It is the rate at which you can do work, "work" defined as applying a force through a distance. That force may be causing acceleration (F=ma), it may be overcoming friction (aerodynamic or rolling resistance), or it can be lifting weight against gravity.

After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
