Name ____________________

Look at the following two distance time graphs of a falling coffee filter and a falling book.

                        
     Graph 1                                                                 Graph 2

1.) Which graph is of a falling coffee filter? Why?

         b.) Which is of the falling book?  Why?

2.) What was the starting distance of the filter ____________ of the book _________________

Here are the same graphs only this time they show the end time of the fall.

                 
        Graph 3                                                              Graph 4

3.) What was the ending distance of the filter _________________ of the book _____________?

4.) What was the falling TIME for the filter______________ of the book ________________?

5.) What was the average velocity of the filter _____________ of the book ______________?

6.) Compare their average velocities.  Why are they the same or why are they different?

Here are the velocity time graphs for the coffee filter and the book

         Graph 5                                         Graph 6

7.) Which is the V vs. T graph of the coffee filter ___________ and the book ______________.

           b. Explain how you know the difference between the two

8.) What was the maximum velocity of the coffee filter_____________ the book ______

Look at the following screen shots for a V vs. T graph  of a falling object.  Calculate the slope of the line using the points provided (velocity is in meters/sec and time is in seconds)

9.) What is the slope of the line? ( show work)

10.) What is the know acceleration of gravity?

11.) Are these two numbers close?  Explain why or why not
