  1. A simple snap-back mousetrap is a clever machine. With just a few parts (a wooden base, a spring, a metal bar, and a trigger mechanism) it can do its job quickly and efficiently. When a mousetrap is set, the spring in the center is compressed, becoming a source full of potential energy. This energy is being stored, not used, but as soon as the trap is released, it is converted to kinetic energy (the energy of motion) that propels the snapper arm forward. This is a perfect example of conservation of energy. It takes an amount of force to set the mousetrap and when the trap is triggered, it c

    It so cool to think that color absorbs light and that different colors mixed with each other creates different colors.

    When I bought my racket, the sales person said that the lower the tension of the strings, the more power but less control you get. But the higher the tension, the more control you have but less power.
  4. It must take a lot of energy to even move the cruise shape just because of its sheer size!
  5. Would the amount of air you blow or how fast you blow air into the saxophone affect the vibrations in the air?

    So the 20 pound weight lifts and holds the 320 pound picture in the air like it's in equilibrium.
  7. Wow that's really cool how the ecu can measure how much oxygen and gas is being used and then if there is to much convert it into a high rate of combustion.

    Would you able to change the frequency of the whistle by making the whistle bigger or smaller?
  9. The speed of any wave/the speed of sound depends upon the properties of the medium through which the wave is traveling. But first if there is no medium for the wave or sound to go through, then there will be no sound. For example, there is no medium in space so there is no waves/sounds travelling in space. There are two factors that effect speed of sound. One of them is the elastic properties of the medium/material. Elastic properties of an object is how easily the object is able to bend or deform when a force is acted upon it. So the phase of matter effects the elastic properties of the
  10. Oh so since energy can't be destroyed or created and the velocity is a constant, the only thing that has to change to conserve the energy is the mas.
  11. A couple of summers ago, my family and I went to Hersey Park for vacation. I'm afraid of heights but I love to go on roller coasters and I remember that there was a Ferris wheel that my sisters persuaded me to go on. It was scary because you could see how high you were from the ground. But it was also cool because you could see everything. Anyways, a Ferris wheel can be related to physics because of its shape. It is related to centripetal force and torque. So basically, I could calculate the torque that a rider feels on the Ferris Wheel. All I need is the radius, the mass, and the linea
  12. When I was a kid, my parents bought me a yo-yo. At first I was puzzled and wondered how to play with it. I spent a good amount of time practicing and I could finally make it roll and then come back to me. I thought that was a huge accomplishment, but then I saw on TV a yo-yo contest with these people doing insane tricks with their yo-yo. I never knew how they could do it. So I decided to see the physics behind a yo-yo. I found that when people do string tricks that makes the yo-yo roll on the string is due to friction. There is friction between the string and the axle that prevents the yo-yo
  13. Our brain are set up to receive and interpret messages from the eye. Optics, a branch of physics, studies the interaction of the light and the eye. This interaction plays an important role in optical illusions. Optical illusions use light, colors and other features to trick the mind into thinking of things that are or aren't there. For example the Lilac Chaser Illusion. In this optical illusion, the viewer sees purple blurry dots arranged in a circle around a focal point. As you stare at the plus sign, it will appear as if a space is running around the circle of lilac discs. But after the view
  14. Jenga, it's the classic block-stacking, stack-crashing game that everyone played as a kid. You and the person you played with, stacked up pieces of block into a sturdy structure and then you remove these blocks from the bottom or middle and placed them on the top. As you removed a block from the structure you had to be careful of how you removed it because one wrong twist or turn, you could collapse the structure and lose. The reason why it's so hard to remove the block from the structure because there is a friction on the block that resists you from pulling the block fast and smoothly. If the
  15. Did you know that you transfer about ninety percent of your force upon a pedal of a bike into kinetic energy? Riding a bike is so simple but there is so much physics behind it. As you ride a bike there are multiple forces on you. There is a force of gravity downwards on you, so as you slow down, the force of gravity will push you and the bike down. There is also a drag force and frictional force acting on you and the bike. The drag force is the air resistance you feel when you go downhill. If you're going at a high speed with your bike then you can feel the air resisting you from going down th
