Force A push or pull exerted on an object in order to change the motion of the object (measured in newtons).
Amplitude The measure of how much energy is being carried by a wave.
Trough The lowest point of a wave.
Crest The highest point of a wave.
Mechanical Waves Waves that require a medium.
Wave Specific patterns of water, sound, and light.
Longitudinal Wave Particles of the medium move parallel compared to the direction the wave is moving.
Compression A region in a longitudinal wave where the particles are closest together
Rarefaction A region in a longitudinal wave where the particles are furthest apart.
Transverse Wave Particles of the medium move perpendicular compared to the direction the wave is moving.
Medium The material through which a wave can travel.
Electromagnetic Waves Vibrations of electric and magnetic fields whose waves do not require a medium.
Wavelength The distance from any point on a wave to the next identical point on the same wave.
Frequency The number of waves that pass a point in a given amount of time.
Hertz The measure of frequency.
Wave Speed The speed that waves travel.
Work The use of force to move an object some distance (measured in joules).
Power The rate at which an object moves (measured in watts).
Cullen pushes a shopping cart with a force of 9.0 newtons in a straight line for 12 meters. How much work was done? W=F x D W=9.0 N X 12 m 108 J
A small motor does 8000 J of work in 20 seconds. What is the power of the motor? P=W/T P= 8000 J / 20 s 400 W
The speed of a wave is 5 cm/s and the wave travels 50 cm, find the time it took the wave to travel that far? T=D/S T=50 CM / 5 CM/S 10 SECONDS
What is the trough in a longitudinal wave? The rarefaction.
Which waves require a medium? Mechanical Waves.
What is power measured in? Watts.
Newtons is the measurement for ______. Force.
The rest position of a wave is also known as the _____________. Line of equilibrium.
