Unit 1 was our introduction to Physics. We learns a lot new and interesting concepts such as, relationships, scientific notation, measurement, graphs, and variables. We also got to see physical demonstrations such as pendulums.

These pictures are of two functioning metronomes. Metronomes are used in music to keep the tempo or beat of a song. A metronome is an example of a pendulum and although they are usually electrically operated these two pictures show how even if the mass of the pendulum changes the period stays the same. Before this lesson I would have had a hard time believing that both of these metronomes could have the same period.

  1. Hey we used the same example, thats cool! we also both thought that mass would affect the period when in fact it didn't, how similar we both learned something new!

  2. thats cool, i never would have connected pendulums with a metronome! it is really hard to believe that these two metronomes, even though one can fit in your hand and one is as big as a building can have the same period!

    1. I know I thought it was crazy that the two metronomes could have the same period

  3. Wow that's so cool how you came to that conclusion! It's weird because a pendulum swings downwards but a metronome swings upwards, they're total opposites! We both learned how mass doesn't affect a period but only length does so we got to learn something new!

    1. I thought it was sort of like an upside down pendulum and yah I thought it was crazy how mass didn't affect the period but length did
