My Research/Experiment

My Question

Which affects a cars top speed more, torque, horsepower, weight, or height?



My Hypothesis

My hypothesis is weight AND horsepower will affect the top speed the most.



Definition

Torque-The tendency of a force applied to an object to make it rotate about an axis, the magnitude of the torque is equal to the magnitude of the force multiplied by the distance from its point of application to an axis of rotation.



Horsepower-The power needed to lift 33,000 pounds one foot in one minute, which is actually about 1.5 times the power of a strong horse.

How?

My process to doing this will compare, calculate, and determine what affects the top speed the most. What I will do is compare each car's HP, Torque, Height, Weight, and Top Speed. This will help me show what is the most effective. After that I will see if there is relation between these statistics.

The Ferrari

Ferrari 430 Scuderia

Horsepower-510hp

Torque-347 lb-ft

Weight-2775lbs

Height-47.2

Top Speed- 198 MPH

The Lambo

2009 Lamborghini Murcielago Lp460

Horsepower- 630

Torque- 487 lb-ft

Weight- 3400 lbs

Height- 44.7"

Top Speed- 211 MPH

The Cobra

2009 Shelby Cobra GT500
Horsepower-500hp
Torque- 480lb-ft
Weight- 4000
Height- 54.5"
Top Speed- 155MPH

WATCH MY CAPZLE!!!!!

Conclusion I

What I've noticed is that if the car's horsepower is over 500 it will go at least 150Mph IF it has a reasonable weight. For example, the Cobra has 500hp and weighs 4000lbs and goes 155 Mph. The Lambo has 610hp and weighs 3700lbs, but goes 210Mph. Then the Ferrari has 510 hp, yet only weighs 2000 Lbs so it goes 196Mph. This shows that weight AND horsepower affect the car alot.
