The materials will be used by the used to study motion (position, displacement, velocity, and acceleration) for the Physics class using a motorized cart. The students will be able to practice constructing position vs. time and velocity vs. time graphs for a motion. Student instructions In this lab you will observe and measure the motion of a motorized cart by marking its position along a strip of tape at regular time intervals. Note that you can adjust the speed of the cart using the small dial - find a speed that works well for you and then do not change the cart's speed during the experiment. Once you have a record of the cart's motion, you can measure and record its position in a data table and construct a position vs. time graph for the cart's motion. You can then calculate the displacement and average velocity of the cart during each time interval, and construct a velocity vs. time graph for the motion. Although you will work as a group (3 students) during this lab, each student will turn in their own lab report. Using the lab students will be able to reflect on the following questions How do successive displacements of the cart compare? Why? What is the slope of the position vs. time graph? What is the significance of this value? How would the position vs. time graph be different if the cart had gone faster or slower? What is the slope of the velocity vs. time graph? What is the significance of this value? Was the velocity of the cart more-or-less constant during its motion? How do you know? How would the velocity vs. time graph be different if the cart had gone faster or slower?
