So I'm pretty much doing lab report on air resistance. I need help writing it out: introduction, theory, Appartus, procedure (needs formula), and conclusion.Please help Since the part 2 was cut off :Procedure:Part 21. With about 20 g of sand in the ballon blow up the balloon as big as possible (without braking it). Using a string looped around the ballon measure the circumference (C) of the ballon. Using formula: A= C2/4 pie calculate the area of the balloon 2. Drop the balloon and calculate the acceleration due to the air resistance as above three times.3. Let some air out and repeat steps 1 and 2 three times.4. Use your data to graph the acceleration due to the air resistance versus area.

Theory The affect of air resistance depends upon three things: the mass of the object, the size (area) of the object and the speed of the object. The more massive an object the less affect air resistance has. The more massive an object is the easier it is for the object to push air molecules out of the way. The less massive an object the harder it will be to push air molecules out of the way and the slower it will accelerate due to gravity. The larger the area the more air an object has to push out of the way and the more effect air resistance will have. The area we are considering is the cross section area of the object (the area you would see looking up at the object). A good example of this would be a parachute, which because of it large area will slow down the fall of a person. Lastly, the faster an object moves the more air it has to push out of the way, which means that there is more air resistance. When an object is dropped, it starts to accelerate due to gravity, but as it speeds up air resistance starts to increase (due to the increase in speed). The air resistance will increase until the push upwards equals the pull downwards due to gravity. At this point, the net acceleration of the object is zero and the speed remains constant called the terminal velocity. Apparatus: 1. Balloon 2. Sand 3. Meter Stick 4. Lab Stool 5. String 6. Computer with Interface Procedure: Part A 1) Measure the acceleration of the balloon when it is dropped using the computer to plot a graph of velocity . vs. time. The acceleration is the slope of the line. You will need to do this 3 times so you can take the average of the acceleration. 2) Measure the mass of the balloon in grams. 3) Using the acceleration due to gravity (9.8 m/s ) and the result of step 1 to calculate the acceleration of the balloon upwards due to air resistance by subtracting the measured acceleration from the acceleration due to gravity. Place about 20 g of sand in the balloon and repeat steps 1-3. Do this 4 times increasing the mass each time. 5) Use your data to Graph the acceleration due to air resistance versus mass. Part B 1) With about 20 g of sand in the balloon blow up the balloon as big as possible (without braking it). Using a string looped around the balloon measure the circumference (C) of the balloon.
