Physics is a class taught by Mrs. Chase where we learn the material for Physics 1, Physics C, and some of Physics E and M. Throughout the year we cover topics such as kinematics, energy, momentum, circular motion, and rotational motion. Learning through live demonstrations and both independent and collaborative labs, the class uniquely covers AP content.
In this lab during our kinematics unit, we were asked to find the acceleration of a cart traveling on an inclined plane. A cart was released from varying distances and passed through a photogate sensor, in which we recorded the velocity for several attempts and distances. We then used our physics knowledge of the four basic kinematic equations to graph the average velocity and calculate an experimental acceleration. Finally, we documented our work in a lab format that you can see to the left, which allowed us to learn how formal reports like these should be written.
Towards the end of B term, we completed the Dynamics Investigation Lab. Working in small groups, my partners Anika Karre and Yerin Kim wanted to explore the effects of increased weight on an object in terms of its coefficient of friction. Hypothesizing that this coefficient of friction would remain the same, we tested this by testing different pulling forces five times on a wooden block and measuring the force using a Vernier motion detector. Collecting this data and then graphing the normal vs. pulling force, we concluded that since there was a linear relationship between the two forces, the coefficient of friction did not change. Although the percent of error was not ideal due to the angle at which the block was being pulled changed frequently, this lab taught us a lot about friction and dynamics in general.
