Science Fair

Particle is another type of physics. It involves protons, neutrons, and electrons. Protons have a positive electric charge and neutrons have the same mass as protons but do not have an electric charge. Electrons have a negative electric charge. These all can relate to electromagnetic structure and forces.

One common known method that was and still is used is the scientific method. It basically uses old information or knowledge and compares it to the new information. The conclusions are usually drawn from observations and the different experiments studied. Most are usually based on hypothesis and predictions. In my project I will be studying vibrations. There are two types of vibrations, free and forced. Free vibration is when something is set off or hit and its allowed to vibrate freely. For example if you tap a spoon on a glass or steel pot top and let it ring. This is free vibration because it will eventually ring and vibrate until it finally gets low and stop. Forced vibration is when there are different kind of forces applied. For example when something is off balance and it is a working machine it will shake or move. This movement is an example of forced vibration because the more vibration depends on the amount of force that is applied on this object.

Sound and vibration is very closely connected. The vibration of objects connects to our ears to help us hear and understand sounds. This also connects back to sound waves. These waves can relate to terms like wavelength, period, amplitude, intensity, speed, and its direction. Wavelength is the distance between wave points in a sound wave or electromagnetic wave. In Physics speed is considered a quantity and does not keep up with its direction meaning that it could go any direction and does not keep up with its path. Amplitude is the maximum length of vibration measured from the position its physical balance. Polarization also plays a big role of the oscillations in a wave and its direction. It
