Question 3.1

Choose settings that cause the car to speed up. Take a picture of each of your graphs, using the camera icon next to each graph. Submit your position-time AND velocity-time graph below.

Question 3.2

Looking closely at the graphs you just created, if you HADN'T seen the car moving next to it, how would you know the car was getting faster? Be specific about what you're looking at on the position-time AND velocity-time graphs.

Question 3.3

Now choose different settings that cause the car to speed up (don't just change the numbers -- think about what the numbers mean and then change them accordingly to get the car to go in the opposite direction). Take a picture of each of your graphs, using the camera icon next to each graph. Submit your position-time AND velocity-time graph below.

Question 3.4

Looking closely at the graphs you just created, if you HADN'T seen the car moving next to it, how would you know the car was getting faster? Be specific about what you're looking at on the position-time AND velocity-time graphs. Are these different factors than what you identified in Q3.2?

Question 3.5

Using the simulation, give the car a negative acceleration value and any velocity value & watch its motion. Start the car, but stop its motion before it turns around (if it does). Does the car speed up or slow down?

Question 3.6

Now just change the sign of the velocity that you used in the previous question (Q3.5) -- if your original velocity was +6, now make it -6 or if it was originally -2 make it +2. Let the car go and stop it before it turns around! Now does the car speed up or slow down?

Question 3.7

Based on your observations, if a car has a negative acceleration what does that tell us about its motion?
