The physics of typing this blog


CoreyK

871 views

So I'm sitting here, pushing down on keys, listening to music and all of this is physics.

Both sitting and typing are examples of newton's third law, all forces come in pairs. My fingers are hitting the keys just as hard as the keys are hitting my fingers and my butt is pushing down on the chair just as hard as the chair is pushing back on me. (Fn=Mg)

Now the music is not Newton's third law, it has to do with sound waves and how the vibrations from the headphones travel through the air and are received by my ear drums and processed and understood as sounds by my brain.
