This meeting's goal was basically to gather experimental data from an air track (which is virtually frictionless) set-up wherein a cart was pushed (with constant force- using a retractable pen) a variable distance (from 5 m to 45 inches close to the other end), taking note of how long it would take to complete its travel. The angle of the air track was also another manipulated variable (which was done by stacking books one on top of the other).
We were quite late this meeting because we rushed the lab report for the activity prior to this meeting. When we entered the room, our classmates were already gathered around the air track doing the experiment. I was assigned to record the time it took for the cart to reach the other end for a while but I was unable to try actually pushing the cart.
From raw experimental data, it became evident that the farther the distance from one end, the longer it took for the object to reach the other end. Applying a constant force in a frictionless surface entails that the acceleration of the object applied with the force is constant. Its velocity would increase in x increments per unit second. It was also evident that increasing the angle's measure would make it quicker for the object to reach the other end (due to the acceleration due to gravity).
The lab meeting was quite fast since the activity wasn't really that demanding. I realized this lab meeting that I knew only a handful of my classmates personally, and that I should be more sociable as to be able to enjoy the lab meetings in its entirety.
