Energy Types
Energy of MOTION (Objects)
Ex: Running a mile
Kinetic Energy
Heat transfer through TOUCH
Ex: Skillet, Hand Warmer, Branding Iron
Conduction
A wave that oscillates vertically (up & down) as it moves horizontally (left & right) and requires a medium to travel through
Waves bouncing off of a surface
Ex: Light shined upon a mirror
Reflection
↑________ = ↑ Energy
↓________ = ↓ Energy
Amplitude
Energy of POSITION (Gravitational)
Ex: Holding an object at a great height
Potential Energy
Heat transfer through CIRCULAR MOTION
Ex: Hot Air Balloon, Air Fryer, Boiling Water
Convection
A wave that oscillates horizontally (left & right) as it moves horizontally (left & right) and does not requires a medium to travel through
Longitudinal Wave/Electromagnetic Wave
Waves bending when entering a new medium
Ex: Observing a “broken” pencil in a glass of water
Refraction
↑_________ = ↓ Frequency
↓_________ = ↑ Frequency
Wavelength
POTENTIAL ENERGY + KINETIC ENERGY (Machines)
Ex: Riding a roller coaster
Mechanical Energy
Heat transfer through ELECTROMAGNETIC WAVES
Ex: The Sun, Light Bulb, Microwave
Radiation
The distance between one part of a wave to the same part of that wave
Wavelength
Waves bending around corners or through openings
Ex: Shouting at a friend that ran out the door
Diffraction
Wave Speed from Fastest to Slowest
Solid - Liquid - Gas
Vaccum - Gas - Liquid - Solid
Mechanical Waves
Electromagnetic Waves
Energy cannot be CREATED nor DESTROYED, but can be TRANSFORMED
Law of Conservation of Energy
Low Molecular Motion
Medium Molecular Motion
High Molecular Motion
Solid
Liquid
Gas
The number of wavelengths that pass one point in a given amount of time
Frequency
Similar waves combining to reinforce one another
Constructive Interference
The change in wave frequency caused by the relative motion between a wave source and an observer.
Doppler Effect
Energy of VIBRATING MEDIUMS (Solids, Liquids, and Gases)
Energy of MOVING ELECTRONS (Lightning)
Energy of ELECTROMAGNETIC WAVES (Electromagnetic Spectrum)
Energy of MOVING PARTICLES (Phase Changes)
Energy of SPLITTING/FUSING ATOMS (Fission & Fusion)
Energy of BREAKING STORED BONDS (Food, Batteries, and Chemical Reactions)
Sound Energy
Electrical Energy
Light Energy
Thermal Energy
Nuclear Energy
Chemical Energy
Heats up SLOWLY (requires more energy to heat = insulator)
Heats up QUICKLY (requires less energy to heat = conductor)
↑ SHC
↓ SHC
The distance between the resting point and the highest or lowest part of the wave
Amplitude
Different waves combining to cancel one another
Destructive Interference
The _______ _______ results in a ______ frequency when the source and observer move toward each other and a _____ frequency when they move away
Doppler Effect
Higher
Lower
