I ended up using the hose, where pressure occurred inside when the valve opened up. Water pressure overcame the inertia between the water pressure and the closed valve when it opened. Water flowed through the hose until it came up to the nozzle. gravity, however, also overcame the water's inertia, as it fell to the grass.

I was playing my violin, and noticed the sound energy that came out when the strings vibrated, creating compression waves inside the violin, and the hollow inside amplified the tone.

Alex and I had been working on an experiment where electrons, or electrical energy, is transferred through the air between two insulated copper coils.

This morning, the container of apple juice slipped out of my hand and hit the ground. Inertia was involved because gravity had been an unbalanced force acted upon the container of juice. Then, gravity had been balanced when the juice hit the floor and stopped the juice.

I read an article on how an EMP works. It creates a powerful electromagnetic field to surge into devices, frying circuits. Also, conductors, like phone and power lines, can receive the fluctuation and transfer down the line to any devices connected to the conductor, frying them as well.

This morning, Chris L. was playing an electric base for orchestra. I noticed how the magnetic strings flucuate the magnetic force on the pickup when plucked. An electrical current is formed, and travels out a wire into an amplifier, where the electrical current makes sound using speakers.
4.23.10
I realize that my earphones are speakers reduced to a small size. Electrical pulses flows through wires and into the speakers, where a transformation of energy occurs. Magnets in the speaker become active when the electrical pulses activate a series of separate magnetic forces. The two magnetic forces oppose each other, and press against a paper cone. The pulses cause the magnets to fluctuate, and the fluctuation causes the cone to push forward and sink back. This causes compressions and rarefactions in the air and officially turns the electrical energy into sound energy.

When I turned on my flashlight last night, I realized that a completed a circuit for electrons to flow through, starting with the battery. Electrons flow through metal wires, which are conductors, and surrounded by plastic insulator. Electrons move into the light bulb in the flashlight, creating a chemical reaction to make light as well as heat. Then the light waves spread out from the light bulb, diffracting through small spaces.

I saw my sister lifting some rubber bouncing balls and dropping them to the floor. Gravity brought the ball to the floor. The force that hit the ball when it hit the bottom was reflected and pushed the ball upwards again. Then gravity took over and started the process. The height of the bounce depended on the velocity of the ball when it falls, as well as the mass and density.

Years ago, I remember getting hit by a car. The velocity of the car was directed towards me. The acceleration had forced my ribs inward. The speed of the car was about 25 miles per hour, but it still hurt. However, with friction in the car's brake disks, the car stopped before any more damage could happen. Friction, however, rubbed against my knees and elbows, scraping off the skin. But because of gravity, the brakes, and me, inertia occured because unbalanced forces acted upon the car.

I had taken apart an airsoft shotgun, and realized how it works. The spring-powered clip, full of mechanical energy, pushes the 0.12 gram airsoft pellet into the feeding system, which is held back by a barrier before falling into the airsoft's firing chamber. When I pump the gun, the pump forces back the barrier, as well as locking the spring-forced hammer back. When I pull the trigger, the mechanical energy inside, which is a series of levers and springs, releases the hammer, which was full of potential energy. The full kinetic energy that was in the hammer right when it hit the firing chamber forced a handful of air into one small space. The pellet was pushed out of the chamber with high acceleration. Sometimes, the motion energy in the pellet creates sound energy when it escapes the gun's chamber. Fluid friction caused by the air around us can easily affect the pellets velocity.

My dad stubbed his toe one day. As he yelled, I noticed that when someone steps, motion energy carries each foot forward alternatingly. Inside the leg, mechanical energy is used when muscles contract and bring the leg forward on a pivot in the leg, aka: leg joints. Tiny jolts of electrical energy cause the muscles to contract. Our center of gravity also propels us forward by moving it forward, giving us momentum. When my dad yelped from the sudden pain, sound energy reverbrated throughout the house.

I had observed an eliptical machine during PE. I noticed that the person used force and gravity to push the pedals down and rotate the wheel and axle in the back. I also noticed that adding resistance slows down the eliptical machine using friction. There is also a couple of levers that served as handles for the eliptical machine. Motion energy filled the machine, as well as the thermal energy that built up when I used the eliptical machine.

I also know that a building uses simple machines as well. An elevator uses a special pulley system to elevate and lower the car. Doors are levers. Wheelchair ramps are inclined planes. If the building is a hotel, th concierge carts use wheel and axles to move around.
2.23.10
I realized that a regular car is full of simple machines. The doors are levers, as is the stick shift. The tires and steering wheel can be wheel and axles. Inside the engine, the timing belt can be a pulley system. The seats (and maybe the spoiler and front bumper) are inclined planes. The car itself could be a wedge, dividing the air. There could also be screws on the tires' suspension to hold the wheels onto the axle.

As simple as this is, I find drinking apple juice as part of the science world. I realized that there was one gallon, for volume, of juice inside the container. The weight was about seven pounds. It was a liquid matter, partially a solution. Then when I poured into a cup, I noticed that gravity, combined with the simple machine, the inclined plane, the juice was able to pour into the cup.

I was just thinking about the element cobalt. I never knew what it looked like for sure, so I looked it up. It turned out to be a solid metal, with the symbol being "Co." The atomic number is 27, and the atomic mass is about 59 amu. There were 27 each of protons and electrons, and 32 neutrons. It is classified as a "Transition Metal" and has the color of silver. There are about eight isotopes, with one of them as a stable atom.

Just now, the speaker in my left earphone popped out of the earpiece (i thought Sony was "high-quality.) I also noticed that it was forced out because force was exerted onto the speaker. The force squeezed the socket, from both gravity pulling the mass as well as the balanced force from the surface the earphone was on.

I learned how the Sun works. The Sun has a combination of Hydrogen and Helium. The Sun is also a mass that has it's own gravity. The gravity is what holds the Sun's gases together.

I watched my cat as he tossed the mouse around the room. Every once in a while, there is potential energy before he flings it across the room. Then there is kinetic energy right before the mouse hit the ground after it was tossed.
1.21.10
When I went camping, we lit a small campfire with wood and matches. There was a chemical change and change when my dad sparked the tip of the match and lit it up. There was also potential energy right before he tossed the match and kinetic energy right before the match landed in the wood. There was another chemical change when the wood caught fire. There was also a physical change before we even got the firewood: when the wood was chopped up for transport.

Moving on with cars...
Inside a car engine, there is a powerful chemical reaction. Pistons are forced down by an explosion of a mixture of oxygen and gasoline, using force and kinetic energy to rotate an axle. The axle is part of a simple machine. In fact, a car is filled with simple machines. The timing belt is a pulley system. The pistons are a part of a pulley system to rotate the axle. The steering wheel on a car is a wheel and axle.The stick to shift gears is a lever.
When I rode a bike, I also realized that it was built on simple machines. The gear shift is part lever/part inclined plane. The gears are a series of wedges. The chain and gears are a pulley system. The bike moves on two wheel and axles.
One time, I rode down a hill and fell unconscious when I flipped forward. The force of my motion exerted from down the hill to towards the ground, giving me a concussion.

Well,
As me thinking about cars and what not, I notice how cars work.
When the tires rotate, friction allows the tires to move the car. This movement shows two of Newton's Laws of Motion. The law of inertia, an object at rest will stay at rest. The car was at rest until the tires created energy to move the car forward. Also, action-reaction comes in mind. The action is the tires were rotating. the reaction is that the car moved forward.
