Car Physics

            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 turning the weight of the car goes to the opposite side unloading the inside tires. The article explains says that inertia acting through the center of gravity causes this and these effects are proportional to the height of the vehicle, which is why racecars are usually low to the ground. To be a good race car driver it is very important too first understand weight distribution. .
             The second part of the article explained some basic calculations used in motor sports. The first equations is distance = velocityXtime. This equation is used to find any of the previous variables. The next equations uses acceleration measured in G's. The equation is Distance=half accelerationXtime squared. Understanding how to calculate these equations is essential for racing teams to determine what adjustments need to be made to the car to make it run faster, smoother, and move efficient. .
             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.

STAGE 2 PHYSICS THE PHYSICS OF CAR RACING INTRODUCTION Physics is the science of measurement. ... The only reason a car in neutral will not coast forever is that friction, an external force, gradually slows the car down. ... The second law: When a force is applied to a car, the change in motion is proportional to the force divided by the mass of the car. ... As long as the tires stay on the car, the ground pushing on them slows the car down. ... The rotational tendency of a car under braking is due to identical physics. ...

3. Automotive Physics Article Running in 2nd Gear?

Matthew Sill's article, Physics and the Automotive Industry, on the physics behind automobiles seemed lacking in major areas. ... Sill describes that as the car moves faster, the drag force increases, and because the drag force can not be easily reduced the cars, therefore, tend to max out at 200mph. ... I also think it would have been useful to the reader if he had mentioned some of the newer materials used in cars to make them lighter, as well as the older ones they replaced; in both the engine and the car body itself. ... Sill finds it necessary to input his own thoughts on the develop...

4. Car Safety

That is why car safety is so crucial. ... Airbags are a crucial part of car safety because it actually works on two laws of physics, Newton's 1st, 2nd and 3rd Laws of Motion. ... Without car safety, many lives would be lost, but more importantly, without physics, such applications would not exist. This is so because car safety is mainly dependant upon physics, especially Newton's Laws of Motion. Physics can be found in so many everyday uses yet it is rarely noticed but its applications and uses are broad, diverse and important. ...

7. Drift

Drifting is getting your car to slide sideways down a road. Then, using a car's momentum , to propel it around a turn, all the while maintaining control. ... There are two ways to do a drift: 1) Put the car into second gear, let the car rev up around the turn and then throw it in to gear at the right moment to pull out. 2) Pull the e-brake to cause the wheels to lock up whipping the rear of the car around a turn and then release to regain control coming out of the turn. ...
