journal 5

This summer, my friends and I went to Alan Davis. My friend and I tried doing different jumps, but nothing as crazy as landon and gavin's jumps. This is me just stepping off of the edge and attempting to look graceful in free fall haha. When I am standing on the edge of the log, i have potential energy relative to the water (PE=mgh) but not kinetic (KE=1/2 mv^2) because i am not moving. As soon as i step off the edge, I then have kinetic energy but the potential energy decreases because of the decrease in height. When i hit the water, i have kinetic energy but no potential energy in relation to the water. The total energy when i was standing on the log must be equal to the energy at the end of the jump. It was a lot of fun jumping off the log and free falling was super fun. I don't know how much more potential energy i could handle before i get too freaked out to jump tho!! (no way to spiting caves lol)
