Today was the second day of class. We studided about the concept of motion and did the experiment with the toy car. We measured the distance and the time interval of the car moving across the table.
Next, we did the lab with the photo gate timer. We found that gate mode starts a timer each time something moves across the beam. In pulse mode, moving through the beam stopped the timer, so it is like a stopwatch. Pendulum mode started a timer and stopped the timer after crossing the beam twice. This mode is used to measure the time interval of how long it takes for a pendulum to create a full oscilation.
Lastly, we received a few handouts. One paper was the major concepts sheet for unit 2. Another was the Chapter 2 packet which we have to read by monday. Next was the bogus worksheet which is also due Monday. Homework 2A is due on Monday. Finally, The FCI/Force and Motion Conceptual Evaluation is due Monday.
