Energy
Stored energy that COULD make something happen.
A push or a pull exerted on an object.
a force
This is a disturbance that moves energy from one place to another.
a wave
Sound is this type of mechanical wave.
longitudinal
It is the study of how matter and energy interact.
Physics
mechanical energy
Force that is no longer balanced causing a change in the motion of an object.
Unbalanced force
The highest and lowest point of a transverse wave
crest (highest) and trough (lowest)
A rapid back and forth movement that causes compressions and rarefactions
vibration
It is the study of the structure, makeup, and changes of matter.
Chemistry
It is used energy that IS making something happen.
kinetic energy
"I say UNBALANCED, you say.........." If forces are unbalanced, this will ALWAYS happen.
motion
Waves that can travel through matter OR empty space.
Electromagnetic waves
Sound waves are longitudinal and that means that the particles (matter) are moved in the same direction as the wave. This is called what kind of movement?
parallel
It is the field of science (big, huge field) that studies matter and energy.
Physical Science.
It is kinetic mechanical energy that IS causing an object to move.
Forces that are equal in size and opposite in direction.
balanced forces
In a longitudinal wave where the particles are close together.
compression
The wave length in a longitudinal wave is from what to what?
compression to compression
A force of attraction between all objects in the universe.
gravity
It is potential mechanical energy that COULD cause an object to move.
Stored mechanical energy.
A resisting force - a force that pushes back on a moving object.
friction
In a longitudinal wave where the particles are far apart.
Rarefaction
The unit of measurement used to measure intensity in a sound wave (soft and loud).
decibel
For mechanical energy, this is required to act on an object.
