Things will fall from left to right

High or low, at any height

Grab a marble, make it metal

And perhaps a stress ball that's mellow yellow

Now drop them both and watch them go

Which one hits first? Oh no one knows!

So this is the problem, the dilemma for you

To find a way of predicting the fall of ball one and ball two

Drop them, record them, then tell me what do you find

About dropping two objects at the very same time?

Object The objective of this lab is to find a way of prediction the order in which several objects, when dropped at the same time, will hit the ground.

Methods

In order to find how fast something would hit the ground when dropped in the air, we first had to incorporate what different factors came in to play when something was free falling in the air. We hypothesized that air resistance was one of the main reasons why one object might fall faster than another object. In order to test this we decided to test out what we knew in several separate steps.

1. Obtained nine different types of balls

. Measured the circumference of each ball with a piece of string and then measured the string and wrote down the data.

. Measured each ball on a scale to determine the mass of each ball (in grams).

4. Using the formula that is typically used to find circumference ( r), we worked backward to find the radius of each ball.

5. Using the information found in step four we used the formulas 4 r to find Surface Area, 4 r / to find Volume and D = M/V to find density for each ball.

6. After all the information was recorded into a data chart we used a stop watch to record how long it took each ball to drop to the floor from meters off the ground.

7. After recording this information we then analyzed our findings to come up with a suitable reason for why each ball fell at the rate that it did.

Data and Analysis

Explanation

Our results showed us that although each object dropped has a different mass, surface area, volume and even density, the rate at which they all fall is initially at the same rate, of an average of about .7 seconds for every meters. Also by taking in account the different sizes of surface area for each object we were able to determine which ball would fall slightly (.05 seconds or less) faster than another. Our final conclusion was that the larger the surface area of an object, the more air resistance there was and the slower the ball would fall.

Conclusion and Reflection

We learned that objects will fall at the same rate, unless their surfaces areas are extremely different; and in the case of the waif ball if there are holes in the object it will create a greater air resistance on the object. For those attempting to do this lab in the future, we suggest that you measure and drop your objects more than once so that you are sure that your information is accurate.
