Physics at the beach


During class day at Kailua, we all had lots of fun, some more or less than others. While I was pondering over whether that stinging on my arm was a jellyfish or a sunburn, my toe made contact with a rock, scratching it with immense pain. Later I discovered two good Samaritans pulled the rock out of the water and discovered a crab! An as they raised that crab menacingly up to me, i was struck by how that crab's former home changed my foots momentum. As I was walking through the water, I was at a somewhat, sorta, kinda, in a sense, moving at a constant speed. When I struck the rock the impulse of the impact causes a quick change in momentum, thus resulting in a large change in force leading to my toe being stricken with pain. If I took my time before kicking the crab's home i would've experienced less force on my toe and the crab probably would still be at rest at the bottom of the beach.
