What is Energy??
• Is the ability to do work…..
Now try it in your own words:???• An ability to cause change

What are the types of Energy?
• Potential • Kinetic• Chemical• Thermal• Electromagnetic• Electric• Nuclear

What are the two main types of Energy?
• Potential• Kinetic
All other energies fall under one of these two. Make a chart with your lab partner and place the types of energy under one of these.

What is the law of conservation of Energy?
Energy cannot be created or destroyed.
However… energy can be transferred.

Waves
• Transfer energy from one place to another

Types of waves
• Longitudinal waves• Transverse waves

Transverse waves
• Up and down• Examples:
-light- The Wave
- See transverse waves

Longitudinal Waves
• Examples:– Sound- See longitudinal waves

Parts of the Wave
• Wavelength- distance from crest to crest, or trough to trough

Parts of the Wave
• Amplitude- height of the wave

Describing a wave
• Frequency- the number of waves made in one second
• Measured in hertz (Hz)
