[QUOTE="Saltydawg, post: 158325, member: 2944"] Ok next its important to understand exactly what force, power, work, torque and horsepower are and how they relate to each other. I thought I was gonna have to type out a long explanation but I found a really cool site that walks through them in everyday language instead of the lingo used in engineering school and by scientists. [url=http://www.howstuffworks.com/fpte.htm]http://www.howstuffworks.com/fpte.htm[/url] This site takes you step by step through pretty much all the forces used in figuring out how fast something will move and how much power you need to do it. There are a few other concerns in drag racing that don't apply to other objects but the basic math is all the same. Horsepower is a measure of how much work can be done over a given period of time. An engine makes torque but Torque alone does not express how much work can really be done because it does not adress the speed that work is done. Horsepower addresses both the ammount of torque that is being applied and how fast its being applied. Horsepower is a measure of work actually done. It does not measure potential. A higher horsepower engine will ALWAYS do more work. It might not always be practical but that is another matter :). [/QUOTE]
