Purpose: determine the relation between air resistance force and speed.
Theory: Use the data we recieve from drop the coffee filter to get the velocity
Apparatus: For this lab we drop five coffee filters, one at a time from a balcony inside a building. We recorder the fall from each filter and use logger pro to help plot the points to form a position vs time graph. Then we use excel by applying a mathematics model to recieve the velocity.
The y axis was use for the position, while the x axis is for the velocity. To get the air force we have add up the function of the shape and the speed. We were able to get the velocity from the position and time. The air resistance was the mass times gravity. We then graph the air resistance as the y axis and the velocity as the x axis. Their were uncertainties for both values.
Here is the equation we use.
Then we use excel.
Excel work the way wanted but there was a number that was way off from the others that concern us.
