During the past two weeks in class we have done a lab to measure: speed,battery discharge, mass, power level, time, acceleration, gravity, height, mgh, and power used. During this experiment we used the lego mindstorm to power to motor that was connected to several 20g weights.

 

 

During the experiment my partners, Sarah and Brandon, and I just changed the amount of power and the mass and observed how different variables changes other variables such as acceleration, speed, and time.

Day One of Experiment:

Day Two of Experiment:

Through this experiment my partners came to the conclusion that the reduction mass increased the acceleration. We also came to the conclusion that decreasing the power decreased the acceleration. While many conclusions can be drawn through this experiment one of the things I learned was that the higher the power level the more energy is used. With those results the conclusion can be made that when power is used to it’s full potential it is more efficient.
