Use this activity to assist your student in analyzing ticker tape for speed, velocity and acceleration! Field-tested with hundreds of students and years in the classroom, designed to get maximum results with minimum time invested for both student and teacher!
Once your students have gotten the hang of working with the basic motion equations they'll need to be able to analyze motion in the lab. One of the most common methods is to use ticker tape and a spark timer to analyze the speed of the tape.
While you certainly want to get students to analyze actual tape in the lab, many students will need extra practice. This activity can serve as a 'warmup' for the lab to smooth the lab process or as a reinforcement after the lab to ensure students are properly analyzing their tapes!
Furthermore, almost all students get torn apart (at least initially) differentiating between speed/velocity and acceleration. Activity 3-8 switches up both the starting location and the acceleration pattern (leftward or rightward) of the dots, requiring students to really understand what's going on. The problems showcase samples of tape in different stages of motion - both initially at rest and initially moving.
Activity 3-8 also requires students to use a timer's frequency (either 10 Hz or 40 Hz in these questions) to determine the period between dots on the ticker tape. This, for me, is the first time I talk about frequency during the course, and adds another element to this activity.
Materials are provided in PDF format to ensure that you'll get accurate and consistent measurements year-to-year! Key is color-coded to show where measurements are applied in each question.
The NYS Regents Exam used a sample tape (initially at rest) as an extended response section a few years ago, so this concept is certainly fair game in the future.
Correlates with standards and questions on the New York State Regents Exam in Physics. Also aligns strongly with many other standardized test questions in linear motion (AP Physics 1/2, SAT II Physics).
