EXPERIMENT:   Data Collection

 

 

Predictions:

 

  1. What's the fastest you think you can comfortably pitch in miles per hour?

 

  1. What are the reasons for your prediction?

 

  1. Would you call your prediction a guess, a hypothesis, or something in between? Explain why.

 

 

2. Collecting data on pitching speeds

 

Name                             

Distance (m)

t1(s)

t2 (s)

t(s)

Avg. t (s)

Avg. speed (m/s)

Avg. speed (miles/h)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

         

 

Compare your results to your predictions.  How well did you predict?

 

 

3. Calculations with computers and spreadsheets:

 

How do the average times and speeds calculated by your spreadsheet program compare to the manual calculations you made on the same data in Part 2? If they differ in any way try to explain why.

 

 

 

4. Measuring the motion of a bowling or other large ball:

 

What do you predict will happen to the distance the ball moves as a function of time? Will the ball move at a steady speed, speed up, or slow down after it leaves the bowler's hand? Why?

 

 

 

 

 

 

Time:

2-m Distance

Time:

4-m Distance

Time:

6-m Distance

Trial 1

 

 

 

Trial 2

 

 

 

Trial 3

 

 

 

Average time:

 

 

 

 

 

Graph your data for the distance your bowling ball traveled as a function of the rolling-time of the ball. This graphing should be done both by hand and on the computer. Don’t forget to discuss these in your conclusions.

 

 

  1. Compare the shape of the graphs you produced in Section 4 with the sketches shown in the lab manual. Would you say that the distance in­creases with time, t? Decreases with time? Is it a linear function of t? Is it proportional to t? Explain.

 

  1. How do the results compare with the prediction you made in Part 4? Were you surprised?

 

  1. What do you think would happen to the slope, m, of the graph if the ball had been rolled faster? Would it increase? Decrease? Stay the same?

 

5.  How the ball's distance varies with time:

 

A.    Compare the shape of the graphs you produced in Section 4 with the sketches shown above. Would you say that the distance in­creases with time, t? Decreases with time? Is it a linear function of t? Is it proportional to t? Explain.

 

B.     How do the results compare with the prediction you made in Part 4? Were you surprised?

 

C.     What do you think would happen to the slope, m, of the graph if the ball had been rolled faster? Would it increase? Decrease? Stay the same?

 

hi, i need help with an economics homework. Is all about calculating GDP and stuff. 

Tesla Motors

 

Psychology background is essential.....Must have excellent reviews....

 

 

I need help with this paper.. must follow outline of graph which I will attach. Need done by 9:30 PM Central time. Please follow instructions per proffessor  Thank you!!

 

Case scenerio.

 

Jane and John are brother and sister. They are also fraternal twins. Interestingly, even though they are siblings within the same family—and twins—they react quite differently to their environments. Jane is outgoing and never meets a stranger. She enjoys large gatherings of friends, participates in many extracurricular activities in school, and is a cheerleader and captain of her volleyball team. She loves to travel, meet new people, and experience different cultures. Her twin brother, John, is a quiet and studious young man. He loves to read, and he listens to classical music. His has a small, intimate circle of friends who share the same interests. He is not at all interested in sports. He is captain of his school’s chess team; in fact, his idea of the perfect sporting event is a chess competition. When it comes to travel, he would prefer to stay home—unless he is traveling to a chess competition.

 

 

In this assignment we will compare and contrast biological and behaviorist theories to better understand and demonstrate the differences between this brother and sister.

 

To prepare, review the readings for this week.

 

Submit by Day 7 a paper that includes the following elements:

 

  • Compare and contrast biological and behaviorist theories
  • An explanation of the strengths and limitations of each theory
  • Apply the behaviorist theory in explaining the differences in the siblings
  • Apply the biological theory in explaining the differences in the siblings
  • A brief discussion of which approach you think makes the most “sense” and why.
  • Graph included, must follow graft outline
