100
When a wave bounces off a boundary often what you see in a mirror.
What is reflection
100
The transfer of heat through materials by the direct contact of matter
What is conduction
100
Force times distance, unit of measurement is a joule.
What is work
200
Mathematical relationship describing how the intensity of light diminishes with distance
What is the Inverse Square Law
200
The energy of a single photon is related to its frequency by the formula E=hf
What is Planks Constant
200
Device that measures the wavelength of light. each individual color is called a spectral line because each color appears as a line.
What is a spectrometer
200
releases heat and forms bonds the opposite of endothermic
What is exothermic
200
Objects bounce off each other with no loss in total kinetic energy.
What is elastic collision
300
Energy cannot be created or destroyed although it can be changed from one form to another.
What is Law of Conservation of Energy
300
Measures the ability of a material to stretch. rubber has more _____ than steel
What is elasticity
300
a penedelum is an example of this. A system in harmonic motion.
What is an oscillator
300
energy in motion. energy of a ball sliding down a hill after it has been released
What is kinetic energy
300
when it has equal amounts of both charges
What is electrically neutral
400
The force of attraction between two objects is directly related to their masses and indirectly related to the square of the distance between them
What is Law of Universal Gravitation
400
The direction of current flows from positive to negative just like in a battery
What is Direct Current
400
the lowest or bottom point of a wave
What is a trough
400
energy flows from hot to cold to reach a medium point, no heat flows because the temperatures are the same.
