WGU C165 Unit 2,3 & 4 Scientific Inquiry,
Physics & Chemistry Practice test Exam
Questions with Complete Solutions 2024/2025
Chemical potential energy - correct answer the energy stored in the chemical bonds of
a substance
Elastic potential energy - correct answer Energy stored by something that can stretch
or compress
Electrical Energy - correct answer energy that is carried by moving charged particles,
such as electrons
Electromagnetic energy - correct answer The energy of light and other forms of
radiation.
Thermal energy - correct answer The total energy of motion in the particles of a
substance
Law of Conservation of Energy - correct answer the law that states that energy cannot
be created or destroyed but can be changed from one form to another
Wave - correct answer a disturbance that transfers energy from one place to another
Oscillation - correct answer a repetitive motion that usually occurs about a center point
or equillibrium
Equilibrium - correct answer a position or state to which an oscillation object eventually
returns after a disturbance is gone.
Medium - correct answer Material through which a wave travels
, Mechanical Waves - correct answer waves that require a medium to travel
Electromagnetic Waves - correct answer A form of energy that can move through the
vacuum of space. Can travel through both matter and a vacuum (in the absence of
matter)
Transverse Waves - correct answer A wave in which the particles of the medium move
perpendicularly to the direction the wave is traveling
Longitudinal waves - correct answer a wave in which the particles move parallel to the
path of the wave
Compression - correct answer The part of a longitudinal wave where the particles of
the medium are close together.
Rarefaction - correct answer a part in a longitudinal wave where the particles are
spread apart (expansion)
Wavelength - correct answer Horizontal distance between the crests or between the
troughs of two adjacent waves
Frequency - correct answer the number of complete wavelengths that pass a point in a
given time
Amplitude - correct answer Height of a wave
Crest - correct answer Highest point of a wave
Trough - correct answer Lowest point of a wave
