❭ In this class, taught by Mrs. Chase, we take an algebra and calculus-based approach to investigate and model connections between concepts, equations, and graphs. Through classroom discussions and collaborative work, we’ve learned about kinematics, dynamics, work, energy, power, and other mechanics concepts. We’ve also designed lab apparatuses and analyzed data. Two such labs were the Acceleration on an Inclined Plane and the Dynamics Lab.█
In this lab, we designed an experiment to obtain the acceleration of a cart as it moved down an inclined plane. To do so, we constructed ramps using a track and books and completed trials where we measured velocity and distance traveled. Using these experimental values, we used kinematics and linearization to derive a method of determining the cart’s acceleration. Here is the full lab report for this experiment.
In this lab, we were offered creative choices in designing our own lab to examine the properties of dynamics. I worked in a team with Ethan and Kayla, and we decided to try to experimentally obtain the static coefficient of friction of a table by using a modified Atwood machine. The masses connected to the Atwood machine were a block, which rested on the table, and a cup, in which we poured water until the block moved. We then used dynamics to calculate the static coefficient, a process which I’ve detailed in the lab report included here.
