Experiment 2: Force and Energy, Velocity and Acceleration, and Power.

Me and my partner Maria Sidenko were given a unique opportunity to see how Newton’s 2nd Law works in real life in our Science&Innovation class. Our task was to use the Lego Mindstorm motor to lift weights with a pulley in order to see how Newton’s 2nd Law works. Newton’s second law of motion shows the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables – the net force acting upon the object and the mass of the object. We were using the VI to converse the results into the excel format which we later used to calculate Power, Acceleration as well as see how visually the results are(By creating a “Scatter” and a “Trendline”). We got the following table:

2 3 We have computed the potential energy by using the formula: Potential energy = m*g*h. Then we determined how the battery energy drainage changes throughout the experiment.  Since the energy of the battery was converted to the potential energy of the masses, we had greater masses and as a result got the greater battery drainage.  The experiment clearly showed us how the Newton’s 2nd Law works and how the potential energy is converted.

In the lab experiment which we did last class we were practicing the Faraday’s Law. We were shaking a tube which had a magnet which traveled through a coil of wires.  We were supposed to show that the faster we shaked the tube, the greater the generated voltage would become. By using the VI program me and my colleague Marina Sidenko obtained the following results.

Here, it is noticeable that the more shakes there were – the greater the the sum of the squares of the voltages had become. This experiment showed us how the generated voltage increased and how the Faraday’s Law worked. I would like to thank my colleague Marina S. for the great job!
