Finally the weather begins to warm up which mean it's time for flip flops! As I walked through the commons the other day wearing my flip flops, I noticed how slippery the tile floor was... luckily I did not fall! Then I thought about wearing flip flops in the winter and how often I would fall due to the slippery ice, not to mention my feet would be very cold. I came to understand just how important friction is in the winter because, without it, we would be sliding and falling all over the place. The soles of winter shoes, for example, tend to be very grippy and have lots of ridges in them. These ridges provide the shoes with a less likely chance to fall over on the ice because they create more friction. Also, there are snow tires many people buy for their cars during the winter because the roads get very icy and these tires provide more friction between the car wheels and the ices, which will prevent the car from potentially getting into an accident. Good thing car tires manufacturers as well as shoe companies took into consideration all the physics that goes into creating more friction because otherwise people would be falling and getting into car accidents more frequently. And on the bright side, we don't need to worry about this for a while since spring has finally arrived!
