The physics of driving

A lot of people will be driving a lot of kilometres over the next few months, as Canadians rush frantically around the country to make the most of summer. Unfortunately, quite a few accidents will undoubtedly result, some of which could be prevented if people better understood the physical forces at work when they drive their cars. The most important thing to remember is that a car weighs a lot, which, as Isaac Newton pointed out, means that once it's moving in a certain direction, it will continue moving in that direction until quite a lot of force is applied to it. It has "inertia." Inertia means that your car ...

Future cars

Like many other small boys, I was fascinated by cars, not least because my oldest brother was a bit of a car guy and subscribed to cool magazines like Car and Driver and Motor Trend. Every so often, one of those magazine (or other cool magazines like Popular Science and Popular Mechanics) would run an article on the "Car of the Future." They featured way-out styling and things like (I swear I saw this more than once) small nuclear reactors as power sources. Yet, frankly, my car doesn't do anything that my brother's Studebaker didn't do. It goes, it stops, it burns gasoline, it plays music (albeit it via a CD player rather than an AM radio). I still have to steer ...

Car sound

One of my earliest childhood memories is of sitting in the front seat of my father's Studebaker, listening to the Beatles. Since those early days in Lubbock, Texas, I've listened to a great deal more music in many more cars. In the Studebaker, and in the '63 Plymouth that followed it, if you wanted to listen to music, you listened to AM Radio. But then in the early '70s we got the Toyota--and my brother installed an eight-track in it. We didn't know it then, but that was just one shot in a revolution that led to today, when most cars (including my own) have stereo systems far superior to the one in ...

Car care

I like my car a lot. But I have to admit, it doesn't look as good as it used to. And probably yours doesn't either. That's because the moment your car rolls out the factory door, its finish starts to deteriorate. It's not too surprising, since a car's surface is attacked by ultraviolet light, ozone, heat, acid rain, industrial fallout, squashed insects, bird droppings, tree sap, road salt, and even hard water. Of course, as I mentioned last week, the first step in fending off the damage from all these things is painting the car, but you want more than just color: you want a shiny, reflective coating that will ...

The science of tires

It happens to all of us sooner or later. We're in a hurry, we head off in our car--and discover we have a flat tire. This happened to me twice in December, and got me thinking about tires, which is unusual, because usually we don't think much about tires at all. After all, they're pretty simple devices, aren't they? They're just round rubber doughnuts pumped full of air, right? Wrong. The modern automobile tire is really as much a technological marvel as the car itself, a complicated device made of thousands of individual pieces created from dozens of materials. Of course, they weren't always so complicated. The first pneumatic tire, or "elastic bearing," patented in ...
