Blog 6 but should be 7 or 8

Surfing is a wonderful example of physics at work in my life. Beyond the obvious concept and physics of waves. Every turn I make while surfing is possible because of a centripetal force. When I start my turn, here a very basic, slow bottom turn, the rail of my surfboard angles into the water. This creates a normal force perpendicular to the point of contact between my board and the water. This normal force allows me to make wide or sharp turns even though the water has a low friction on my board because the component of the normal force pointing toward the center of my rotation. Thank God for physics and surf!

Physics blog 5 or somethin

The flow rider is pretty hard. But fun too I suppose. I would guess that a lot of physics goes into creating something like this. The creaters had to make the power of the water strong enough to fight gravity but not so strong as to shoot someone off into the air by the force of it. The water is flowing up te ramp thingy to keep me from sliding down. Since I can move on the wave-ish thing the force isn't totally in control. By gaining moment and moving my weight I am able to decide where I want to go on the wave. Ride creators must know a lot of physics to be able to create rides of all kinds that do such amazing stuff. PHYSICS IS FUN!

Blog 3 "workin out"

My sister Coral and I were doing some push-ups and it made me think of physics. Every time Coral pushes herself up she feels her normal force pushing against the force of the earth. The earth is pulling all 25 kg of her at a force of 245 N. Thus she has to push up with a force of 245 N to move up at all and if she moves up accelerating then she is pushing with a force greater than 245 N. After about 200 push-ups the force the earth was pulling on her was just too much and gravity defeated coral.

Wakeboarding

I go wake boarding often and thinking about trajectory of objects reminds me of being in the air when I wake board. I have to start outside the wake and greatly increase speed and angle moving towards the wake. At my greatest speed i hit the wake and launch into the air. My vertical speed increasingly slows to zero when I it the peak of my jump then i return back to the water in hopes of a soft landing. The horizontal speed at which I hit the wake stays constant until I land back on the water. Physics is greatly influential on how I wake board and what i can do. Physics can be fun!!!!!!

Photo Shoot

I am jumping for a photo shoot. In the picture I am in free fall while my friend matt is sitting on the sand motionless. My acceleration is exactly -9.8 m/s/s. Therefore, I am being pulled back to earth by gravity 9.8 meters every second. My acceleration is constant untill I hit the ground and my velocity is constantly decreasing.
