In our class on 2/01/12 we experimented with Newtons law of motion: F=Ma.

 

Using a string pulley connected to the Mindstorm Battery and a set of weights, we looked at the changes in acceleration with a constant power level and changing mass, and then a constant mass and changing power level.

First, we set up our pulley and battery.

Then we set the power level on Labview to a constant rate of 75. When adjusting the mass, we added or subtracted weights from the pulley to determine  how the changes will effect the speed of acceleration. We did 4 runs.

Next, we set a constant mass of .21kg and adjusted the power level to see how that would effect the speed of acceleration. We also did 4 runs with a constant mass.

Conclusions:

It became clear through 4 trials that the more mass an object has the less acceleration, at a constant .

We also learned that increasing the power level, while keeping the mass constant, the acceleration will increase.

 

 

 

Using lab view and excel, we tracked the changes and then graphed the conclusions.
