#### Transcript of The Physics of Marching Band

The Physics of Marching Band
Vectors and Displacement:
The two main concepts of physics used in marching band are vectors and displacement.
In marching band, each member goes from set to set, and each move is a vector.
During a show, the speed of a movement can change ((such as 112 beats per minute)) and acceleration can occur based on each individual's step size.
Distance and Displacement
Each member moves a certain distance to make a shape on a field.
Every band member goes a different distance.
To measure the total distance, you could graph each vector and add the distances together.

If you take the last point and the original point and draw a straight line between the two, you will find a vector. The length of this vector will be the displacement.
Physics in Color Guard
All guard work is affected, and dependent, on gravity
Tosses must be thrown with enough force and momentum to reach a specific height, before coming back down at the exact moment needed.
Depending on the type of equipment used, the object has to move in a certain direction at different speeds.
In order to do anything, you need enough momentum to get the equipment to do what you want it to.
Woodwinds
The air column determines the pitch.
A sound wave can travel down that column, reflect back, and start over.
Flutes are the only instruments of the woodwind family without reeds.
A reed, which is unique to the woodwind family, is a thin strip of material that vibrates to produce sound
Brass
Brass instruments are any tube that can be played with the lips.
Most brass instruments have a long, cone-shaped tube and a flaring bell. Usually, the tube is coiled to make it easier to hold.
Brass instruments have metal mouthpieces; the larger the mouthpiece, the lower the sound.
Percussion
Marching band percussion is split into two categories: mobile and stationary.
The Front Ensemble ((or "Pit")) are stationary. The boards, such as marimba, vibraphone, and xylophone, make noise by resonating when hit by rubber, brass, plastic, or tightly wound yarn mallets..
The Battery ((or Drumline)) is mobile. The drums, such as snare, tenor, and bass, have hollowed out bodies that amplify sound when the stick hits the membrane stretched over it.
Final Questions
1. What are the two most used physics concepts used in marching band?
2. What physics concept most affects Color Guard?
3. What is the only woodwind instrument without a reed?
