Data Collected from Car Test Time in SecondsDistance in MetersSpeed in m/s 000 0.721 1.39 0.902 5.56 1.533 1.59 1.684 6.67 3.35 0.62 Total Distance: 7.22 meters Total Run Time: 5.79 seconds Average Speed Over 5 Meters: 1.52 meters/second

Data Analysis of Velocity From the start to meter 1, the velocity of the car is increasing because the slope increases.

Data Analysis of Velocity From meter 1 to meter 2, the velocity of the car is increasing because the slope is increasing compared to the slope from the start to meter 1.

Data Analysis of Velocity From meter 2 to meter 3, the velocity of the car is decreasing because the slope is decreasing compared to the slope from the meter 1 to meter 2.

Data Analysis of Velocity From meter 3 to meter 4, the velocity of the car is increasing because the slope is increasing compared to the slope from the meter 2 to meter 3.

Data Analysis of Velocity From meter 4 to meter 5, the velocity of the car is decreasing because the slope is decreasing compared to the slope from the meter 3 to meter 4.

Data Analysis of Speed From the start to meter 1, the speed of the car is increasing because the data point is higher than the previous data point.

From meter 1 to meter 2, the speed of the car is increasing because the data point is higher than the previous data point. Data Analysis of Speed

From meter 2 to meter 3, the speed of the car is decreasing because the data point is lower than the previous data point. Data Analysis of Speed

From meter 3 to meter 4, the speed of the car is increasing because the data point is higher than the previous data point. Data Analysis of Speed

From meter 4 to meter 5, the speed of the car is decreasing because the data point is lower than the previous data point. Data Analysis of Speed

Analysis of Forces at Each Meter Forces at Meter 0 There are no forces. At meter 0, the car is at zero speed.

Analysis of Forces at Each Meter Continued Forces at Meter 1 Forces are unbalanced in the forward direction. At meter 1, the car is speeding up. Force exerted by balloon on car. Force exerted by air on car. Force exerted by axle on straw. Force exerted by ground on wheels.

Analysis of Forces at Each Meter Continued Forces at Meter 2 Forces are unbalanced in the forward direction. At meter 2, the car is speeding up. Force exerted by balloon on car. Force exerted by air on car. Force exerted by axle on straw. Force exerted by ground on wheels.

Analysis of Forces at Each Meter Continued Forces at Meter 3 Forces are unbalanced in the forward direction. At meter 3, the car is speeding up. Force exerted by balloon on car. Force exerted by air on car. Force exerted by axle on straw. Force exerted by ground on wheels.

Analysis of Forces at Each Meter Continued Forces at Meter 4 Forces are balanced. At meter 4, the car is at constant speed. Force exerted by balloon on car. Force exerted by air on car. Force exerted by axle on straw. Force exerted by ground on wheels.

Analysis of Forces at Each Meter Continued Forces at Meter 5 Forces are unbalanced in the backward direction. At meter 5, the car is slowing down. Force exerted by air on car. Force exerted by axle on straw. Force exerted by ground on wheels.
