Waves
his is the number of wave cycles that pass a point per second.
Frequency
What type of wave can travel through space without needing a medium?
Light Waves
Energy that is stored, like a bike at the top of a hill, is called what?
potential energy
What is the smallest unit of matter that has the properties of an element?
atom
What is the source of electricity in a circuit, like a battery, called?
voltage source
What do you call the top of a wave?
Crest
This term describes how loud a sound is based on what a person hears.
Loudness
Energy that comes from motion, like a rolling ball, is called what?
kinetic energy
This bond happens when atoms share electrons.
covalent bond
This type of circuit has only one path for electricity to flow through.
series circuit
This is the time it takes to complete one wave cycle.
Period
Sound waves are which type of wave: transverse or longitudinal?
Longitudinal Waves
What kind of energy do moving particles have that causes something to feel hot?
thermal energy
A change where something new is created, like burning wood, is what kind of change?
chemical change
When a circuit has more than one path for electricity to follow, it is called what?
parallel circuit
What do waves carry from one place to another?
Energy
What is the unit used to measure the intensity of sound?
decibels (dB)
What kind of energy is stored in a stretched rubber band?
elastic potential energy
A mixture where all the parts are evenly mixed, like salt water, is called what?
a solution (or homogeneous mixture)
In a circuit, this is anything that slows down the flow of electricity.
resistance/resistor
These types of waves need a medium like air or water to travel through.
Mechanical waves
This effect causes a change in the pitch of a sound as it moves toward or away from you.
the Doppler Effect
Energy from the sun that travels in electromagnetic waves is called what?
solar energy
Is ice melting a chemical or physical change?
Physical
The flow of electricity in a circuit is called what?
current
