Copy the problem below into a text editor or word processor.

• This form accepts only text so a text editor such as Notepad is fine.

• You might prefer for your own reasons to use a word processor (for example the formatting features might help you organize your answer and explanations), but note that formatting will be lost when you submit your work through the form.

• If you use a word processor avoid using special characters or symbols, which would require more of your time to create and will not be represented correctly by the form.

• As you will see within the first few assignments, there is an easily-learned keyboard-based shorthand that doesn't look quite as pretty as word-processor symbols, but which gets the job done much more efficiently.

You should enter your answers using the text editor or word processor. You will then copy-and-paste it into the box below, and submit.

A wad of paper is dropped from a second-story balcony and falls through still air to the ground.

• As it speeds up, what happens to the air resistance it encounters?

answer/question/discussion: ->->->->->->->->->->->-> :

As velocity increases, consequently, so does air resistance as the opposing force upward.

• What happens to the net force acting on it?

answer/question/discussion: ->->->->->->->->->->->-> :

As air resistance increases, net force acting downward decreases as a result.

#$&*

• What happens to its acceleration?

answer/question/discussion: ->->->->->->->->->->->-> :

a = net force / m ; thus, as net force decreases, so does the rate of acceleration decrease.

#$&*

• If it dropped from a much higher point, what would happen to the net force and the acceleration?

answer/question/discussion: ->->->->->->->->->->->-> :

Greater height has no different effect in this case. There is no change in net force, no change in acceleration. Air resistance at given instant depends on velocity of object.
