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: ->->->->->->->->->->->-> : ->->->->->->->->->->->-> :
The air resistance remains constant throughout the fall.
&&&&The force of air resistance increases as the object continues to fall.&&&&

• What happens to the net force acting on it?
answer/question/discussion: ->->->->->->->->->->->-> : ->->->->->->->->->->->-> :
The net force acting on it will decrease.
&&&&The net force will remain in the downward direction because of gravity but will decrease in magnitude because of air resistance.&&&&

• What happens to its acceleration?
answer/question/discussion: ->->->->->->->->->->->-> : ->->->->->->->->->->->-> :
The acceleration remains constant because of gravity.
The acceleration begins equal to that of gravity, but eventually decreases in magnitude due to air resistance.&&&&

• If it dropped from a much higher point, what would happen to the net force and the acceleration?
answer/question/discussion: ->->->->->->->->->->->-> : ->->->->->->->->->->->-> :
They would be the same as previously found.
The object would continue to accelerate but at a decreasing rate. The net force will then become closer and closer to zero. As the speed of the falling object increases the acceleration will eventually reach zero.
