Question: Objects that move in a straight line with a constant speed—not speeding up or slowing down—have z…

(1 bookmark)

Objects that move in a straight line with a constant speed—not speeding up or slowing down—have zero acceleration. We call this kind of motion: Uniform Motion. We can identify uniform motion when the object travels equal distance intervals in equal times.

We can identify non-uniform motion, or accelerated motion, when the object travels equal distance intervals in unequal times. Finally, we have two types of non-uniform motion: motion with constant acceleration and motion with a non-constant (or changing) acceleration.

Activity 1

Today you will analyze the motion of a cart traveling along an inclined track. You will begin by doing a thought experiment, predicting the motion of your object. Discuss your ideas among your group…it is okay to disagree!

Sketch an acceleration-versus-time graph for an object, starting with some initial speed, traveling on a flat track. Remember, this sketch is a prediction; what do you think it would look like? Then sketch a velocity-versus-time graph for the same case.

1. Explain the shape of your acceleration graph.

2. Explain the shape of your velocity graph

Sketch an acceleration-versus-time graph and a velocity-versus-time graph for an object, starting with some initial speed, traveling down an inclined track.

3. Explain the shape of your acceleration graph.

4. Explain the shape of your velocity graph

Activity 2

Now, using a track, cart meter stick and stopwatches, you will make some measurements to determine if a cart traveling down a ramp follows uniform or non-uniform motion.

First, mark a start point and end point on your track that is at least 1.5m long.

5. How many time/distance data points, between start and end, will be necessary to determine whether the cart is traveling with uniform or non-uniform motion? Explain your choice. Note: you may want to look at Questions 8 & 9 to help inform your choice.

6. Now, outline your measurement plan (procedure) to make this determination of uniform or non-uniform motion. You procedure should include clear instructions, such that anyone could reproduce you experiment exactly.

7. Create a data table and record your data in the space below.

8. Now you will need to use your data to calculate velocities and accelerations. Recall that we have discussed average velocity as vavg = Δx/Δt as well as vavg = (vi + vf)/2. We also discussed average acceleration as aavg = Δv/Δt. Using these equations, calculate the instantaneous velocity of your cart at each distance/time data point and the average acceleration between each pair of distance/time data points. When you have completed your calculations, organize your results into a table with four columns: time, position, velocity, and average acceleration.

9. Now you will graph your results. Plotting [1] a graph of position (y-axis) vs. time (x-axis); [2] a graph of velocity (y-axis) vs. time (x-axis); and [3] a graph of acceleration (y-axis) vs. time (x-axis). Be sure to fully label your graphs. This may be done on a computer or on graph paper. Attach your graphs to the back of this packet.

10. Based on your data and results, answer the lab questions: does a cart traveling down a ramp follow uniform or non-uniform motion? If it follows non-uniform motion, is the acceleration constant or non-constant? Support your answer with evidence from your experiment.

11. Are you confident in your answer to question 10? Explain why or why not.

12. Now, compare your answer (and resulting graphs) to the prediction sketches you made in Activity 1. Do your predictions match your results? If not, which do you believe (prediction or results) and why?

13. Finally, take some time to evaluate your procedure. Do you think it was an effective procedure? Were there any problems with it? How would you change/improve upon the procedure if you were to repeat this experiment?

1. Let us re-examine the frequency table in question 1 as a summary of observed probabilities.
2. Construct a probability table for the data in question 1. The probabilities reflect the observed relative frequencies of occurrence. The body of the table will show the joint probability of each combination of gender and type of purchase. Include row totals showing the probability of purchase type and the column totals showing the probability of gender. Round probabilities to 2 decimals.
3. Suppose that gender and type of purchase was independent for each possible combination. Construct an idealized probability table that we should have observed if these factors were independent. The row and column totals should remain the same as in a) but the body of the table will change somewhat. Round probabilities to 2 decimals.
4. The table in a) is simply a summary of approximately 1,000 purchases. If HomeStyle were to look at another sample of 1,000 purchases it would get a somewhat different table. Do you think the tables in a) and b) are sufficiently different from each other that you would conclude that the purchasing behavior of females, males and “unknown” are different from each other? For now we are just looking for your opinion. You don’t have the knowledge yet to properly say whether they ae different.
5. Comparing large tables with small differences may hide patterns. If you really want to see differences between purchasing patterns of females, males and unknowns, calculate P{Bed&Bath | female}, P{Bed & Bath | male} and P{ Bed&Bath | unknown}. Repeat this for the other categories. Summarize these conditional probabilities in a table. Use 2 decimals.
6. Does knowing the customer’s gender give you any insight with respect to what the customer is more or less likely to buy?
