Days of Thunder: Your Way, My Way
Physics → Forces → Friction
Cole's coach, Harry, talks to him about the importance of tires in a race. He states that they won't be able to finish a race with the way that Cole drives because he'll run down his tires too quickly. Harry suggests a deal with Cole: run 50 laps any way he likes, then run the laps Harry's way, and finally check the tires to see which tires experienced more damage. After the two runs, the tires with Harry's way of driving are in significantly better condition.
