## Lalalalalalala

When your in the shower belting out songs so know one can hear you i bet you have never thought that singing would have anything to do with physics. Well youre wrong! It totally does! People can not only hear your singing but they can also feel it! By singing, your voice creates vibrations that form into waves. Sound can be represented in wave form. The amplitude of the wave (the height of the wave) is represented by how loud you are singing. The amplitude is the degree of displacement of teh vi

## Physics of flight

Have you ever looked up into the sky and seen a type of air craft fly over your head. Have you ever wondered how that is possible? Many people would think that since an airplane or helicopter is so heavy there is no way that something like that could fly through the air. But through physics aircraft can fly thorugh the sky. there are four basic components of flight: thrust, drag, lift and weight. Also Newton's first, second, and third laws apply to flying. Newton's first law claims that every

## Boxing!

Many people dont realize that there is more to boxing than just hitting someone and trying to knock them out. Physics applies to most of boxing! Energy, momentum, work, power, and velocity all play an important role in throwing a punch during boxing. Before the boxer punches his target he has potential energy which is stored energy,as soon as the boxer punches his target his or her potential energy becomes kinetic energy. Kinetic energy is the energy that a body possesses by virtue of being i

## the physics behind rockets

How does physics relate to rockets? How can people caluculate how rockets will fly given the parameters? Rockets fly mainly because of newton's third law and the conservation of momentum. Newtons's third law states that for every action, there is an equal and opposite reaction. To figure out how a rocket will accelerate you would need to learn about momentum. when a rocket is moving through space with a constant velocity, it is very simple to calculate its momentum. The equation for momentu

## Volleyball through physics

Most people dont realize that there is science through playing a sport. Watching or playing volleyball is a great way to grasp the principles of physics. Understanding physics can be tricky if you just look at the mind boggling equations and such, but by connecting physics to other things, such as volleyball, physics can help you learn in an easier way. Gravity Gravitational force impacts every aspect of volleyball; whether you are serving, passing, or hitting. Gravity will effect every co
