## VibrationsEdit

by Danielle and Matt

### 1. NJ standards addressed in the unit Edit

In this unit, we plan to address the following New Jersey Standards:

#### 5.7.12 B. Energy TransformationsEdit

- Explain how the various forms of energy (heat, electricity, sound, light) move through materials and identify the factors that affect that movement.
- Explain that while energy can be transformed from one form to another, the total energy of a closed system is constant.
- Recognize that whenever mechanical energy is transformed, some heat is dissipated and is therefore unavailable for use.

### 2. Length total (days and periods) Edit

### 3. Prerequisite Edit

What students should know and have done before the start of the unit

### 4. Goals Edit

#### ConceptualEdit

- Learn the difference between vibrational motion and linear and circular motions
- Learn the new vibrational quantities
*period*and*amplitude*

#### QuantitativeEdit

- Learn to write mathematical descriptions of position, velocity, and acceleration of a vibrating object as functions of time
- Learn to write mathematical descriptions of the changing energy of a vibrational system

#### Procedural Edit

- Be able to differentiate between a description and an explanation
- Be able to read the kinematics graphs describing the vibrational motion of an object and extract information about the initial position, amplitude, and period of vibration
- Be able to use motion diagrams, free body diagrams, and energy bar charts to describe and explain vibrational motion
- Learn to control variables in the design of a testing experiment
