Question

1.Hold a single coffee filter in your hand. Release it and watch it fall to the ground. Next, nest two filters and release them. Did two filters fall faster, slower, or at the same rate as one filter? What kind of mathematical relationship do you predict will exist between the velocity of fall and the number of filters?

2.If there was no air resistance, how would the rate of fall of a coffee filter compare to the rate of fall of a baseball?

3.Sketch a graph of the velocity vs. time for one falling coffee filter. (provide data so I can graph on the excel)

4.When the filter reaches terminal velocity, what is the net force acting upon it?

Explanation / Answer

PART A)

Rate of fall do not depends on mass or number of objects

rate of filter is always depends on gravity

which is same for both

PART 2)

again the rate will be same for filter and baseball so both will have same speed

PART 3)

At terminal speed the net force on the filter is always ZERO
