Curated by
ACT
As you headed up the mountain to enjoy your last ski trip, you may have noticed a sign reading: Hazard. Icy Roads Ahead, Put On Your Chains. Putting chains on car tires increases the resistance between the tires and the road allowing the car to "grip" the road. This resistance to sliding is called friction. In this experiment, you will be investigating how to increase and decrease the friction between two surfaces.
