1. Why Does Skin Get Pruney in the Tub?

i'm glad my hot tub could be a source of inspiration for you Dave
2. Studying for the Regents

SO, many people have many different ways to study for the regents physics exam including myself and my friends. First i picked kids from the AP track to help me study for physics because i knew that they would be able to teach me a lot more than if i were studying alone. They did teach me a lot! I drove to pick up Bakari from his house using my car Stanley. Stanley changed potential energy to kinetic energy as it changed gas to moving fuel. I had told Alan, our other study party member, to arrive at two, and i arrived at Bakari's at 1:50. It is safe to say i increased my velocity from the trip to his house to the trip back home. I accelerated uniformly until Bakari told me that i could just use the cruise control. My cruise control turned on and would not turn off until i tapped on the break. This instantly reminded me of the law that an object will stay in motion unless acted upon by an outside force, this outside force being my foot on the break. After running into many red lights we turned onto the bridge which had a different road surface than the street. This caused greater frictional force against the car which made my acceleration increase so that i could get past the high coefficient of friction. When we finally arrived at my house we had to put the top back up on my convertible. This was physics in itself as well. The button i pressed used mechanical energy to get the top closed so we could go inside and study. Of course studying with boys they wanted to listen to music. This music would produce sound waves from my computer and into the awaiting ear drums of us studiers. What they didn't know is my sister was down in the basement practicing for her singing jury. Before we could turn on our music we had to figure out how to block out Taylors music. The sound waves were traveling from the basement up to the living room by using diffraction. Her sound waves went from her, across the basement, around the corner, up the stairs, around another corner and into our ears. Very impressive! Quickly enough the boys grew hungry. I, being the lovely hostess, offered them chicken wing dip. I had to warm it up first in the microwave. These waves created heat and energy to make the chicken wing dip at a good temperature for eating. The mechanical energy of the boys chewing was only accompanied by a refreshing drink. Both boys wanted straws to drink their beverages with. The straws in the can was immediately refracted so we couldn't tell where it was in the liquid. The door opened, my door consisting of potential energy turned to kinetic as Sam entered my house. He ran in, pushed me to the ground and sat on me. his momentum before equaled his momentum afterwards as he tickled me until i got up an hid behind Alan. I couldn't replicate his force by any means because my mass was much less than his however i could remove the attraction between us by moving away from him. Our distance increased which created a smaller force of gravity between us. Alan quickly helped change the subject by swinging his iPod around and around on the wire. Bakari and I were quick to analyze this as having centripetal acceleration moving toward Alan's hand that was spinning the wire. We said that it had a uniform velocity and if we had a timer on our hands or a ruler we would be able to figure out the acceleration. Sam also assisted us with this experiment as he swung his keys in a circle around his hand. He however experimented with the idea that if you were to cut the string the velocity would shoot outside of the circle. He unexpectedly let go of his keys allowing us to see which way the velocity was being allowed to go. The keys shot from his hand and into the wall behind him. All too soon the boys had to leave, however Its safe to say that although they didn't realize it, these boys helped me a lot more than they thought they would.
3. pedestrian etiquette

you know whats messed up?! in Canada people walk on the left side but drive on the right, Aka their physics is all screwed up!
4. Lalalalalalala

That would probably be because no one can hear you
5. Frolicking Frenzy

If you have ever watched me walk down the hallway or walk through gym class or even walk down the street you would notice that I don't walk as much as I frolic. Now some people would call this weird, but I consider it as more exercise and a more fun way to get to places that I need to go. Now tonight on the radio i heard that there is a new fad for exercising called prancercising i believe. This is when you walk you sort of dance instead. I refuse to believe that this idea came from anywhere else than watching your's truly stroll down the street. The switch from potential to kinetic energy is present in all walking however it expands when frolicking. With this greater burst in energy being produced, it is obvious that frolicking is more active than walking. It is more of a work out meaning that eventually you will burn more calories from frolicking rather than merely walking. Frolicking has a higher velocity than walking. This is because while frolicking your adrenaline is pumping and making you want to move faster and more be more creative. With a higher velocity the distance traveled over time is greater! A small walk in between classes is done faster, more efficiently, and with greater fines. The only thing that should possibly go against frolicking is gravity. Gravity is always bringing me down when i decide to frolic. I tend to jump about when i frolic and gravity makes it much harder. The force that is acting down upon me is greater than my mass. However the force acted upon me by the ground when i land is the same as the force that i am pushing into the ground. With frolicking also, Newton's 1st law applies. An object at rest will stay at rest and an object in motion will stay in motion unless acted on by an outside force. The outside force for me would be people whom i run into while frolicking, or walls that i may run into. When i frolic i would prefer this law not to be true just so i could continue on forever uninterrupted. I challenge you now to go ahead and frolic through your last few days of the school year! It's more fun, supplies you with a greater velocity, gives you a better work out against gravity,and it looks a lot cooler than walking!

7. cell phones

iPhone users look at their phones three times the normal phone users? Why would you believe this to be true if there are other smart phones being used as well?

9. The Physics of Sleeping

So even when you are deeply asleep you will not wet the bed with your hand in a bowl of water? That is nice to hear!
10. Volleyball is PHYSICal :)

Yes that does pose a problem Monty, however The down official always mimicks the up official anyways so if the up official blows his/her whistle then the down official can right after it and it would be able to assit the players in noticing when the play stops.
11. Is Iron Man possible?

Do you predict in the future when we do have this technology that people will be selling Iron Man Suits, or similar like ways to fly?
12. IS SPACE TRAVEL POSSIBLE?

Soo are you saying that if we were to find enough energy we could travel through space?
13. Volleyball is PHYSICal :)

This is a good point. With this in mind, the down Reff should then be allowed to whistle with the up Reff when the point is awarded.
14. Volleyball is PHYSICal :)

Yesterday was Regionals for my club team and as I was shuffling around in the back of the court i realized just how much Physics plays part in a volleyball game. To begin any play in Volleyball one of the teams must serve the ball over the net to the opposite side. With the higher levels of volleyball this always means a jump serve. Whether it is a top spin serve or a floating jump serve the player throws the ball up and jumps to go swing at it. The momentum that is created by the approach towards the ball causes the player to accelerate their arm swing and get the ball to travel the 30 feet across the net to the other team. According to Newtons 1st law an object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an outside force. The outside force for a serve would be air resistance. Although there is much more air resistance when one would play beach volleyball, on a court in a gym there is also air resistance. The next step for the team once the ball is served at them is to pass it to their setter. The back row players need to line themselves up with their shoulders squared to the ball and with their arm platform at the correct angle to get the ball up and to the front right of the court. When the passer pass's they get low to the ground and simply stick their arms out to retrieve it. They do not swing their arms in any way shape or form when passing a volleyball. The best technique is to have the ball's momentum from the serve be absorbed into the arms of the passer, thereby decreasing the momentum as it travels to the setter where it will be in a much more controlled setting. The setter then takes the ball from the air and pushes it towards the hitter. The setters use their legs to add force behind their arms. The more force they have behind the ball the more likely that the ball will travel all the way to the pin, or it will be a quick set to a middle or a pin hitter and the blockers on the other side will not know what happened. The swing hitter takes an approach, and uses all of the power in their legs to turn potential energy into kinetic as they jump up into the air, throwing up both arms in the process of finding the ball and gaining height on the ball. With a fast arm swing, and a snap of the wrist the ball is then propelled through the air and will hit the ground, there by stopping the play. When the Referee sees that the ball did in fact hit the ground and was not "pancaked" by the opposing team they will blow their whistle and award the point. The sound waves from the whistle are refracted around each player until they end up registering in the ear drums of each teammate and the play stops. The setter is usually the last one to stop playing because they constantly have their back to the Referee, simply because of the way the court is set up. This leads me to wonder if it would be more productive of them to have the up officials on the opposite side so the sound waves from their whistles are able to reach the setters easier, being that the setters truly control the game. What do you think? Should the referee stand be on the other side?
15. colloids vs. non Newtonian fluids

So the Ooz that we create in 6th grade is the same materials used to create bullet proof glass?
