In our most recent challenge, we were solving for the acceleration of a ball (or any object) at 4 seconds.
In order to do this, we first took our measurements for 0 seconds to 3 seconds every half second.
Thus our first table looked like this:
In order to find acceleration, we squared the time in order to form a linear line. This resulted in a graph resembling:
This graph is based on the following data:
As seen in the velocity vs time graph, our velocity is 11.52 cm/s^2 which in meters is .1152m/s^2
As The formula for velocity is v=1/2a
Thus we know that a= 2v
This means that a=2* (.1152)
A=.2304
When we tested our experiment, our data was that acceleration was .235 thus the percentage of difference is 1.01, meaning that we were within the 10 percent.
