In our last class we did an activity using lego mind storm to explore Newton’s second law F=ma, the relation between force, mass and acceleration.
We used an already assembled robot and attached weights to it. When we press the start button, the robot pulls the weights off of the table. After the weights have reached the top and the robot has stopped pulling the weights, the computer calculated how fast the weights lifted, how long it took to lift the weights, and its acceleration.
We changed the speed that the robot would pull the weights and watched the results change. Once we tried a few different speeds and weights, we were able to transfer the data into an excel file. We used the data in excel to make graphs to visually show our results.
