1. A child is swinging in simple harmonic motion. Where in his swing is the velocity the greatest? (Top, bottom, mid-way on the way up, or mid-way on the way down.)
2. A buoy in the ocean is bobbing up and down repeatedly. Explain why this is or isn't an example of simple harmonic motion.
3. A piece of a glacier falls into the ocean creating a large wave. What type of wave is this and how do you know? (Transverse or longitudinal)
The Attempt at a Solution
1. I think that the velocity is greatest mid-way on the way up, but I'm not too sure.
2. I think that the buoy in the ocean is an example of simple harmonic motion since its movement is repeated.
3. Well, I know it's a transverse wave, but I don't know how to explain why. I would imagine that it's transverse since it has a distinct crest and trough, and because longitudinal has to do with varied compression.
