Lesson 1
The ability to cause a change
What is Energy?
energy cannot be created nor destroyed, it can only be transferred
What is the law of conservation of energy
measure of the average kinetic energy of the particles in a material
What is Temperature?
The change of state from a liquid to a gas
What is vaporization?
The smallest unit of matter
what is the atom
Stored Energy
What is, potential energy
when energy moves from on object to another without changing form
What is energy transfer
the movement of thermal energy from a region of higher temperature to a region of lower temperature
what is heat?
a material in which thermal energy moves quickly
What is thermal conductor?
the tendency of an object to remain at rest
what is inertia
objects have ( . ) if they have mass and height above earth's surface
What is Gravitational Potential Energy
When on form of energy is converted to another form of energy
What is energy transformation
the transfer of thermal energy by collisions between particles in matter
what is conduction
material in which thermal energy moves slowly
what is thermal insulator
a push or a pull
released from bonds of atoms
what is chemical energy
a system that exchanges matter of energy with the environment
what is a open system
the transfer of thermal energy by electromagnetic waves
what is radiation
resource that is available in limited amounts or that is used faster than it can be replaced in nature
What is a nonrenewable resource?
measured in grams
what is mass?
released from nucleus of atoms
what is nuclear energy
a system that does not exchange matter or energy with the environment
What is a closed system
*all matter is made of particles
*particles are in constant, random motion
*particles constantly collide with each other and with the walls of their container
What is the Kinetic Molecular Theory?
a resource that can be replaced
what is a renewable resource?
a disturbance that carries energy but not matter
what is a wave
