what is Conduction?
Transfer of thermal energy that occurs in solids, liquids, and gases when two substances of different temperatures touch
What is Convection?
Heat transfer caused by the rising of hotter, less dense fluids and the falling of cooler, denser fluids
What is Convection Current?
A circular movement of fluids caused by the rising of hotter, less dense fluid and the falling of cooler, denser fluid
What is Heat?
Energy transferred between two objects of different temperatures that moves continually in a predictable pattern, from a warmer site to a cooler site, until all sites have reached the same temperature
what is the Law of Conservation of Energy?
Scientific law stating that energy can be neither created nor destroyed but just changes form
What is Radiation?
The transfer of energy by the movement of electromagnetic waves or subatomic particles
What is Temperature?
Average kinetic energy of all the particles in a material; measured by a thermometer in degrees (usually degrees Celsius or degrees Fahrenheit)
What is Thermal Energy?
The total kinetic (motion) energy of the tiny particles that make up matter; the faster the particles move, the warmer the matter becomes
What is potential energy?
Potential energy is energy stored in a system or object.
What is kinetic energy?
Kinetic energy is the energy of motion.
What is energy Transformation?
Energy transformation is the change of energy from one form to another.
What is Gravity?
Gravity is the force that attracts a body toward the center of the earth, or toward another physical body that has a mass.
What is mechanical energy?
Mechanical energy is a form of energy produced by a machine or any moving part.
What is electrical energy?
Electrical energy is a form of energy made available by the flow of electrical charge through a conductor.
What is light energy?
Light energy is a form of energy that you can see as part of the electromagnetic spectrum.
What is chemical energy?
Chemical energy is energy stored in chemical bonds and is released through chemical reactions.
Energy can never be ________.
Created or destroyed.
When energy changes from one form to another, this is called an _____________.
Energy Transformation.
Nuclear energy is often transformed to ____________________ to make it useful to people.
Electrical energy
When a car's tires spin on the road, friction is generated. In this example, some of the mechanical energy is transformed to ____________ energy.
Thermal
Energy cannot be created nor ___________________________.
Destroyed
What are constants?
Constants are things that must remain the same in an expiriment for a fair test.
What are variables?
Variables are things that can change in an expiriment.
What is energy efficiency?
Using energy wisely; conserving enrgy.
What is thermal energy transfer?
Heat that moves in a PATTERN from hot to cold.
