HP and Weight, this might be a little confusing Options

[celicarocker]

this whole theory is going off something i remember someone saying before. not sure of the exact numbers, but it was something like "every 125lbs you take out adds 4hp" or something like that. anyway, the point is there is a direct correlation between weight and HP.

now onto my main point. people talk stuff like "car A will beat car B becuase they both have the same HP, but car A is lighter" so if car B was reduced to the weight of car A, it would be faster? like if car A is 1900lbs and 150hp, and car B is 2700lbs and 150hp, wouldnt they both be the same speed? its like that old trick question "which would fall faster, a pound of bricks or a pound of feathers" where they'd both fall the same speed. so wouldnt a 1900lb car with 150hp go as fast as a 2700lb car with 150hp?

does anybody get what im trying to say?

there is a huge difference from somethign falling as apposed to somethign needed to be able to pull it.... like think you tring to pull its like think try pulling a beg of briks with ur hands and then try pulling a bag of feathers... which one will u be able to pull faster?

If they both weigh 1 pound, and given a constant kinetic/static friction coefficient, it'll be just as much work. Work = F.s (where F = Force = mass*acceleration, s = distance).
