ENERGY TERMS
The ability to do work.
What is energy?
The measure of the average kinetic energy of the particles in a substance.
What is temperature?
Coal, petroleum, and natural gas are collectively called these.
What are fossil fuels?
The highest point on a transverse wave.
What is a crest?
The bouncing back of a wave when it hits a surface it cannot pass through.
What is reflection?
The form of energy an object has because it is moving.
What is kinetic energy?
Heat always flows spontaneously from this-temperature object to that-temperature object.
What is “warmer to cooler”?
Energy carried by moving electric charges in a circuit.
What is electrical energy?
The distance between two consecutive crests or troughs.
What is wavelength?
The bending of a wave as it enters a new medium at an angle.
What is refraction?
Energy that is stored because of position, shape, or condition.
What is potential energy?
Heat transfer that travels through the electromagnetic waves, not matter.
What is radiation?
Energy released from splitting or fusing atomic nuclei.
What is nuclear energy?
The height of a wave from rest position to its crest.
What is amplitude?
The spreading of waves around a barrier or through an opening.
What is diffraction?
Energy associated with machines and moving parts; the sum of kinetic and potential energy.
What is mechanical energy?
Heat transfer that occurs when warm fluid rises and cool fluid sinks.
What is convection?
The process shown when a car engine turns chemical energy in gasoline into mechanical motion.
What is an energy transformation (conversion)?
The number of complete waves that pass a point each second.
What is frequency?
The phenomenon that occurs when two waves overlap and add or cancel.
What is interference?
The principle that energy can be changed but cannot be created or destroyed.
What is the law of conservation of energy?
The amount of energy required to raise 1 kg of a substance by 1 °C.
What is specific heat?
Sunlight belongs to this family of energy that includes X-rays and radio waves.
What is electromagnetic energy (electromagnetic radiation)?
The equation that relates wave speed to frequency and wavelength.
What is v = f × λ?
The fastest seismic body waves generated by earthquakes.
What are P-waves?
