as i make my jump of Thrill!!!! i feeel as though my body is being pulled straight down to the water and that im experiencing weight less ness. Their is a force called gravity that is pulling my body towards the water. The pull of gracity is towards the earts core. Although i feel weightless for those few seconds i am falling i am not truely weightless because there is still a support force pushing on me. physics is everywhere and it explains my crazy life wooohoo!

You spin me right round Baby right round baby right round
http://coach-al.smugmug.com/gallery/7639568_pPyVY#493866658_29jz4-M-LB here is a picture of one of our volleyball games. I couldnt get the picture because coach AL needs to make money by selling these pictures anyways. In the picture i tos the ball up in the air to serve it. Analyzing the picture i noticed that when i toss the ball i put some spin on it giving the ball rotational intertia. Newtons second law clearly states that an object in motion stays in motion so if i were to ignore outside forces and wind resistance the ball would continually be spinning. As my body is jumping i twist my shoulders to increase the torque so i can hit the ball with a greater force. Isnt physics neato i think so.

Jumping off the ground or the ground pushing me up???
http://coach-al.smugmug.com/gallery/4687593_r3cxn#277201461_Xp7DW so here is a picture from coach al's photo smug mug. Because coach al doesnt allow us to copy and paste pictures i have a link instead. As you can see im pretty high up in the air. befre i approached the ball i now realized how relevant it is to NEwtons third Law of motion. As i am getting ready to jump i exert a force to the ground but what i now noticed is that the ground is giving back an equal amount of force that my legs exerted. Thats crazy so now i know if i want to jump higher i need to increase the force exerted by my legs so that the ground force push will aslo increase.
