Simply Motion and Gravity
Today we finished our pendulum lab and we also compared our data. Additionally, we took some notes on what affects pendulums and what not.
First of all, what is simple harmonic motion? Simple harmonic motion is basically when something carries out a repetitive back and forth or up and down motion. So for example, a pendulum swinging on its own from a string has simple harmonic motion. You can tell when something has simple harmonic motion if it only takes gravity for an object to constantly go back and forth or up and down and also if an object is just constantly making that repetitive up/down and left/right motion.
In my own day, I have witnessed simple harmonic motion from a metronome. Metronomes (the old fashioned ones) only require you to pull the dial back once and once you let go the musical timing device will go back and forth on its own for however long it may go.
I also play the guitar so when I play I notice that when I strum the strings the strings vibrate up and down repetitively for a long time unless you stop the strings. This may be more of vibration but technically all you need to do is touch/pluck the string and the string will move on its own after like with a pendulum or a metronome. Drum cymbals can also vibrate/go up and down after they are hit.
Finally, when I am washing up at home sometimes if there is a basin of water in the sink or whatever and I leave an object in the water that floats it bobs up and down. All I need to do is leave a less dense object in the water and gravity helps the object go up and down and up and down... It is different from the other examples but it has the same principle. I think Cartesian divers are better examples of objects bobbing or one of those things out at sea but generally it is all quite similar.
Bungee jumping may count too! I mean technically once you are left to go on your own you bounce up then down and then up and down due to gravity :D. But I don't bungee jump every day xD.
:D <3 Bye bye!
