Energy Basics
The ability to cause change?
What is energy?
Name at least five forms of energy
the law of conservation of energy
What is: Energy cannot be created or destroyed; it can only be changed into a different form?
thermal energy is measured in this
What are joules?
what is a natural resource?
what is any energy source, organism, or substance found in nature that people use?
the two types of energy
what are potential and kinetic?
the energy of particle vibration in a medium such as air or water
what is sound energy?
this takes place when energy changes from one form to another
What is energy transformation?
The total amount of kinetic energy of the particles moving in a substance is called this
What is thermal energy?
What is a nonrenewable resource?
What is a natural resource that exists in a fixed amount or that is used up faster than it can be replaced?
the energy of motion
what is kinetic energy?
this type of energy is transmitted through space in the form of electromagnetic waves such as visible light, e-rays, and microwaves.
what is electromagnetic energy?
this theory states that matter is made up of particles that are always in motion
What is the Kinetic Theory of Matter?
this refers to the transfer of energy from an object with a higher temperature to an object with a lower temperature
What is heat?
What are fossil fuels?
What are nonrenewable resources formed from the remains of long-dead organisms?
stored energy that an object has as a result of its mass and height above the ground
what is potential energy?
this type of energy is stored in chemical bonds that hold the atoms of a substance together
What is chemical energy?
as the temperature of a substance increases . . .
what is "its particles move faster"?
adding or removing heat from a substance can change this . . .
what is "the properties of matter"
a type of energy source that comes from splitting atoms
What is nuclear energy?
the sum of an object's kinetic and mechanical potential energy is called this
what is mechanical energy?
the energy an object has due to the motion of its particles
what is thermal energy?
when we measure temperature, we measure this
what is the average kinetic energy of all the particles?
name three ways thermal energy is transferred
What are conduction, convection, and radiation?
Name at least 4 alternatives to fossil fuels
What are: solar energy (from the sun); hydroelectric energy (from moving water); wind energy (from moving air); geothermal energy (from heat within the Earth's crust) and biomass (organic matter than can be used as fuel).
