The topic I chose to study for assignment two is the physics behind auto racing. The first article I found on the web was called The Physics of Racing. The first part talked about weight transfers in cars when attempting certain manoeuvres. The second article explained important formulas commonly used by pit technicians. The third article summarised speeds and horsepower. This article helped me to understand the basic physics needed in understanding car racing.
The first step in learning the physics behind car racing is weight transfer when braking, accelerating, and turning. When breaking the weight of the car moves to the front of the car causing over steering. Accelerating in a car moves the weight to the back inducing under steering. When tu
The third article that I read was on speed and horsepower, which are closely related. A car moving could theoretically keep going forever but many forces slow it down. The most influential force that slows down cars is called air resistance or drag. The second and third forces is internal and external friction caused by the force of the tires against the ground and the parts in the car rubbing against the drive train causing deceleration. There are complex formulas to figure out each type of resistance, which were given in the article. If interested check out the attached article. Racecars capable of going 200 miles per hour have at least 650 horsepower and over 350-horse power are used to just to overcome resistance. Understanding acceleration an
