So if the first car’s mass is lighter than the second car will accelerate faster. Analyze Results: I reject my hypothesis that if the first car has less mass then the second car will have a greater acceleration. My data shows that as the first car gains mass the second car will accelerate more‚ for example: when the mass of the first car is at 0 grams it accelerates
