In your notes: Summarize the findings from yesterday's lab discussion. Which factors have an effect on the period of a pendulum?
Learning Goal: I can
- ...compare and contrast the characteristics of both a vibration and a wave.
- ...distinguish between a transverse wave and a longitudinal wave, and identify the identifying characteristics of each.
- ...distinguish between constructive and destructive interference.
- ...describe what factors may affect the speed of a wave.
- ...describe a standing wave and how it occurs.
- ...describe the Doppler Effect.
Today:
- Get a spring and a mass. Make observations of the motion of the mass on the spring. Compare and contrast to the motion of the pendulum - similarities? Differences?
- Find a turntable near you. Tape a marker on it. Make observations as it rotates. In your notes: What similarity and differences between the mass on a spring and the pendulum?
- As we watch the video at this link, make notes in your notebook about the following:
- What observations can you make about the motion of these three objects? In what ways are they similar and in what ways are they different?
- Next, observe only the side-to-side motion. That is, ignore the vertical motion of the pendulum and the front-to-back motion of the circular motion. Describe the similarities of this side-to-side motion.
- What does all of this have to do with the notes you took about waves?? Brainstorm in your notes.
- Make observations as we watch this video. Now answer the question above again.
Assignment:
- Were you gone for the Circular/Gravitational Test? When will you take it?
- Due Tues, 5/1: Read/watch the following resources FOR UNDERSTANDING. Take Cornell or other organized format notes. Among other things, your goal is to be able to do at least the following:
- Compare and contrast the characteristics of both a vibration and a wave.
- Distinguish between a transverse wave and a longitudinal wave, and identify the identifying characteristics of each.
