Types of Energy
the energy of motion. ex: yo-yo, swing, moving water
Kinetic Energy
the number of waves that pass a point in a certain amount of time
frequency
a piece of glass that separates white light into different wavelengths. It also lets you see the colors
Prism
the transfer of heat that occurs when one thing touches another
Conduction
energy that travels as waves and can move through empty space
Light Energy
the distance between a point on one wave and a similar point on the next wave
wavelength
a natural thing that can act like a prism
the transfer of thermal energy as matter moves. Ex: heat that makes something spin
Convection
Energy that is stored in an object
Potential Energy
how high or low a sound is, is called...
Pitch
when light changes speed when passing into a new medium, it bends. What is this called?
refraction
energy that is sent out in waves, like from the sun or heat from a fire
Radiation
Energy due to randomly moving particles that make up matter
Thermal Energy
The higher the amplitude, the more/less energy it has and the louder/softer it is.
more, louder
When light rays bounce off, or reflect from a surface, it is called
Reflection
when two surfaces rub together and cause heat
friction
Energy of vibrations carried by air, water, or other matter
Sound Energy
If a guitar string vibrates more quickly, it will have a ______ pitch
Higher
What color absorbs the most light?
