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.

4. Physics - Extended Experimental Investigation

Introduction The question to be investigated throughout this Extended Experimental Investigation is, whether or not the friction effects the time/stopping distance of a vehicle (in this case, the vehicle being a car). No matter what we are doing, friction is always going to be a part of it – when we walk, when we drive or ride. If there was no friction, we wouldn't be able to drive/ride around and there'd be accidents everywhere. So, in short, Friction is incredibly important to us. There are 2 types of friction, Static and Kinetic. Static Friction is friction which prevents an object from m...

... four main functions of operation: intake, compression, combustion, and exhaust. These four factors are the most critical parts to a car engine, as they make the engine run, and allow the car to move. Gasoline links these four functions together, but is used only in combustion. A flammable liquid like gasoline produces an ... enormous force when ignited, and gives the car engine the power to propel itself. Compression makes the explosion all the more powerful, creating more pressure in the area of combustion. ... The charge is first sent to the distributor, which distributes the charge t...

The Opposition to Movement: Friction Have you ever tried sliding across a frozen pond? Then how about sliding across a soccer field? Notice any differences? Do you ever wonder why you can easily slide across ice, yet skid to a stop on grass? A force called friction is always at work that opposes movement in a certain direction. Friction is a force that is created when two surfaces come in contact and move across each other (Funk and Wagnalls). Many times friction is an overlooked force which has had greater impact on our lives than we would generally think. Without the force of friction our ev...

Experiment I VECTORS I. Objective To determine resultant vector using graphical method, analytical method and verify results using the force table. II. Conceptual Background Physical quantities are not limited to scalars and vectors. In general, there are tensors. Scalar is tensors of rank 0 and vector is tensor of rank 1. Quantities that generally represented by magnitude only are called scalars. Those that are represented by both magnitude and directions are called vectors. When we specify the mass of a book, it is sufficient to give a quantity referring to its magnitude, say 1 kg. Mass, the...

Although both cars were heading at ... and to the untrained person it may seem that driver A just had plain luck on his side however this is untrue.
