Optimal Puck Sliding Temperature

I tested three different temperatures of pucks . For the cold pucks, I froze two pucks for two hours at -14cF. For the two room temperature pucks, I kept the pucks at room temperature (22oF) for two hours. For the two hot pucks, I heated them in the oven until they reached 200oF. To test this I created a device that will release the puck at the same force every time. It has two wooden pegs and a bungee cord as a sling shot to release the puck. My sample size was six pucks (2 for each temperature). I tested each temperature three times with a total of nine trials. The cold pucks went the furthest and the fastest at (8.64 feet per second) with an average distance of 66’8” feet. Since the cold pucks have less friction between the rubber puck and the ice they were able to go faster than the hot and room temperature pucks. The hot pucks moved the slowest (6.48 feet per second) with an average distance of 35’9” feet. Lastly, the room temperature pucks were in the middle at (7.15 feet per second) with an average distance of 49’6” feet . My investigative question looked at whether temperature affects the distance and speed pucks travel on the ice. My results clearly show that temperature does affect both distance and speed and the colder the puck the further it travels. Therefore, I accept my hypothesis because when I heated the pucks, they slowed down due to an increase in friction. Implications of my investigation could be applied to other rubber objects such as winter car tires or airplane tires.
