Waves
A type of wave with particles that move back and forth parallel to the direction of the wave.
Longitudinal Wave
Kinetic Energy
The attraction between electrons and protons is referred to as ___________________.
Static Energy
Spinning electrons in an atom create a ____________ around the atom.
Magnetic Field
Made of two or more circular objects fastened together that rotate about a common axis.
Wheel and Axle
The maximum distance between the resting point and the crest. AKA the height of the wave.
Amplitude
Combination of potential and kinetic energy.
Mechanical Energy
Materials, such as brass, allow electrons to move more freely and are referred to as ____________.
Conductors
A branch of physics that studies the interactions between electric and magnetic fields.
Electromagnetism
Instead of moving an object along an inclined place, you move the inclined plane itself.
The distance between two corresponding points on adjacent waves. This is related to the energy of a wave.
Wavelength
Travels in waves with both electrical and magnetic properties.
Electromagnetism
