A car manufacturer is designing a new, lighter sports car. It has a mass of 1,000 kg. They ran 5 trials to see how a change in force could result in a change of acceleration. Examine the table below to answer the following questions. Table 1: Force and Acceleration Trials Trial Force (N) Mass (kg) Acceleration (m/s2) 1 2,000 1,000 2 4,000 1,000 4 3 8,000 1,000 8 4 12,000 1,000 12 5 1,000 16 Questions: 1a. What are the units of…force? mass? and acceleration? b. Identify the variables of this experiment: Control: , Independent:, Dependent: c. Analyze the data for Trial 2 and Trial 3. How many times greater is the force applied in Trial 3 (compared to 2)? and how many times greater is the acceleration in Trial 3? d. Analyze the data for Trial 2 and Trial 4. How big if the force applied in Trial 2 (compared to 4)? and How big is the acceleration in Trial 2 (compared to 4)? e. Big Idea! For the same object, what is the relationship between acceleration and force? Choose one. i. A big force causes a big acceleration. (direct relationship) ii. A big force causes a small acceleration. (indirect relationship) f. Based on what you have learned, fill in the missing data in Table 1. now
