Unformatted text preview: graph the data. Velocity vs. Distance: Place car approximately 20 cm away from speedometer and the top of the inclined track. Then let car go down and the speedometer will calculate and graph the data. Data: Distance vs. Time: D = .2529m/s t + 0.1226 m Corr. = 0.9990 D T 2 Velocity vs. Time V = 0.4105 m/s t – 0.01178 m/s Corr. = .9999 V T Distance vs. Velocity V = .9001 m/s D + 1.662 m/s Corr. = .9992 V D Conclusion: Acceleration = Final Velocity – Initial Velocity Time The meaning of the slope in the calculated equations is acceleration The y – intercept represents the initial distance or velocity depending on the relationship General Equations: Distance vs. Time: D = ½ A(m/s)T + D (m) Subscript i : initial Velocity vs. Time : Subscript f : final V = A(m/s)T + V (m/s) Distance vs. Velocity: V = 2A(m/s)T + V (m/s)...
