Terms in this set (29)
the ability to do work.
Law of conservation of energy
states that energy cannot be created or destroyed; it can only be changed from one form of energy to another.
energy transferred by an electric current (the movement of electrons or static electricity).
energy transferred via sound waves and vibrating objects.
energy of an object due to its temperature caused by the internal motion of the particles.
energy stored in the bonds of atoms which is released when chemical reactions take place (example: Fuel, Food, Batteries).
energy transferred through waves and light particles (photons).
energy an object possesses due to its motion.
energy an object has because of its position. Also known as stored energy.
Gravitational Potential Energy
energy as a result of an object's height above the ground.
Elastic Potential Energy
energy stored when an object is squeezed, stretched, twisted, etc.
energy of matter in motion.
energy stored in an atom's nucleus.
The transfer of kinetic energy between two objects due to a temperature difference between the two.
the transfer of heat by direct contact between two materials with different temperatures.
a material through which energy can be easily transferred as heat. (Example: Metals)
a material that is a poor energy conductor. (Example: Wood or Plastic)
the transfer of heat through movement of a fluid (liquid or gas).
the circular motion of the liquid or gas due to its density differences that result from temperature differences. The warmer areas of a liquid/gas expand and move farther apart, causing it to be less dense. Therefore warmer liquid/gas rises. The cooler areas of liquid/gas condense (come together), causing it to be denser. This causes cooler liquids/gases to fall or sink.
the transfer of heat through matter or space as electromagnetic waves, such as visible light or infrared waves.
Specific Heat Capacity
defined as the amount of heat energy required to raise the temperature of 1 kilogram of a substance by 1°C. It is a measure of how much heat energy a particular substance can hold.
measures of the average kinetic energy of all the particles within an object.
nonrenewable energy sources including coal, petroleum, and natural gas.
energy used from tapping into the Earth's internal heat.
flowing water creates energy that can be captured and turned into electricity.
created from the splitting of uranium atoms in a process called fission. Fission releases energy that can be used to make steam, and the steam is used to power a turbine to generate electricity.
light and heat energy from the sun.
capturing the wind by wind turbines and turning into electricity.
the organic matter that makes up plants is known as biomass. Biomass can be used to produce electricity, transportation fuels, or chemicals.
