Questions and Answers

What is the first step to analyze the data collected from the experiment?

Determining the starting point on the position-time graph

Recording the results in a data table

Calculating the average of the trials (correct)

Plotting the averages on a velocity-time graph

How can you calculate the velocity of the car from the position-time graph?

Velocity = slope of the graph

Velocity = time x change in position

Velocity = change in position / time (correct)

Velocity = time / change in position

What does a flat line on a velocity-time graph indicate?

Acceleration

Variable velocity

Deceleration

Constant velocity (correct)
