Key Concepts

  • Time and Distance Calculations
  • Optimization of Pit Stop Timing
  • Probability and Risk Assessment
  • Exponential Decay (Tire Degradation)
  • Fuel Consumption Rates

Learning Objectives

  • Calculate the time gained or lost during different pit stop strategies (undercut, overcut).
  • Apply probabilistic thinking to assess the impact of safety cars and weather on race strategy.
  • Model tire degradation as an exponential decay function and predict optimal pit stop times.
  • Analyze fuel consumption rates and their effect on lap times and overall race strategy.

Educator Instructions

  • Introduction (5 mins)
    Begin by showing the video. Briefly discuss the importance of strategy in Formula One racing and how pit stops can significantly impact race outcomes. Introduce the concept of using mathematics to analyze and optimize these strategies.
  • Time and Distance Calculations (20 mins)
    Explain the concepts of undercut and overcut. Have students calculate time gained/lost based on lap time differences before and after pit stops. Example: Car A pits and gains 1.5 seconds per lap for 5 laps, while Car B loses 0.5 seconds per lap. Calculate the net time difference.
  • Probability and Risk Assessment (15 mins)
    Discuss how teams assess the probability of a safety car or changing weather conditions. Have students create a decision tree to analyze different pit stop options based on the likelihood of these events. Example: If a safety car is 30% likely, what is the expected time gain/loss for pitting vs. staying out?
  • Exponential Decay of Tire Performance (20 mins)
    Introduce the concept of exponential decay to model tire degradation. Provide a simplified formula for tire performance (e.g., Performance = Initial Performance * e^(-k*laps), where k is a degradation constant). Have students graph this function and determine the optimal number of laps before a pit stop, given a target performance level.
  • Fuel Consumption and Lap Time Optimization (15 mins)
    Discuss how fuel consumption affects lap times. Explain that carrying more fuel adds weight, which slows the car. Have students calculate the optimal fuel load to balance lap time performance with the risk of running out of fuel. Example: Each 10kg of fuel adds 0.3 seconds per lap. What is the minimum fuel needed to complete the race, considering a 2kg safety margin?

Interactive Exercises

  • Pit Stop Simulation
    Divide students into teams representing F1 race strategists. Provide them with race scenarios (track layout, tire degradation rates, weather forecasts). Have them make pit stop decisions and calculate the expected outcome. Compare the results and discuss the factors that led to success or failure.
  • Data Analysis of Historical Races
    Provide students with historical race data (lap times, pit stop times, weather conditions). Have them analyze the data to identify successful and unsuccessful pit stop strategies. Calculate average lap times and pit stop durations to determine the optimal strategy for different scenarios.

Discussion Questions

  • How does the track layout influence pit stop strategies?
  • What are the advantages and disadvantages of a one-stop vs. a two-stop strategy?
  • How do teams adapt their strategies in response to unexpected events like safety cars or changing weather?
  • How do you think pitstop strategy has changed in F1 over the years?
