The ability to do work
What is Energy?
Transfer of thermal energy by electromagnetic waves.
What is Radiation (electromagnetic energy)?
form of energy made by vibrations and requires a medium in order to travel
What is Sound Energy?
Transfer of energy by direct contact when the particles in a material collide with neighboring particles.
What is Conduction?
amount of matter in an object
What is Mass?
The transfer of thermal energy from one object to another when the objects are at different temperatures by conduction, convection, or radiation
What is Heat transfer?
the measure of the average value of the kinetic energy of the molecules in a substance.
What is temperature?
the measurement from base to top or from head to foot
What is height (elevation)?
the energy of the object due to its motion
What is Kinetic Energy?
Any material that easily transfers thermal energy.
What is a Conductor?
process of changing energy from one form into another
What is Energy Conversion?
Any material in which thermal energy is not easily transferred.
What is a Insulator?
Energy can change in form , but can not be created or destroyed
What is The Law of Conservation of Energy?
A form of energy that is produced by the flow of electric charge through a conductor
What is Electrical Energy?
the rate at which someone or something is able to move or operate
What is Speed?
Potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring.
What is Elastic Potential Energy?
the energy released during fission or fusion
What is Nuclear Energy?
The sum of the kinetic and potential energy of all the molecules in an object.
What is Thermal Energy?
a measure of how efficiently an appliance , building, organization or country uses energy
What is Energy Efficiency?
A form of energy that is produced by the flow of electric charge through a conductor
force that acts to oppose sliding between two surfaces that are touching
What is Friction?
a unit of energy in the International System of Units equal to the energy transferred to an object (or work done on an object) when a force of one newton acts on that object in the direction of its motion through a distance of one meter.
What is a Joule?
Relating to or consisting of electrically neutral groups of two or more atoms held together by chemical bonds.
What is Molecular?
transfer of thermal energy by the movement of atoms or molecules from one part of a material to another due to density differences as materials heat up.
What is Convection?
the energy that an object has because of its position relative to a field or because of the relative positions of its parts
What is Potential Energy( gravitational)
