Trimester 2 Science vocabulary and concepts:
Heat & Energy
Energy
• the ability to cause change
Heat Energy Heat Energy
Potential Energy• the stored energy an object has due to its
position or chemical composition
Kinetic energy
• the energy of motion--the more mass or speed, the more kinetic energy
The Law of Conservation of Energy
• states that energy can neither be created nor destroyed

Electrical energy
• energy of moving electrical charges
Electromagnetic energy
• energy that is transmitted through space in the form of electromagnetic waves
Thermal energy
• the total amount of energy from the movement of the particles in an object
Chemical energy
• energy stored in the chemical composition of matter
Sound energy
• energy produced by the vibration of particles that people and animals can detect
Mechanical energy
• energy that moves objects
Nuclear energy
• energy stored in the nucleus of an atom
Heat
• the flow of energy from a warmer object to a cooler object
Temperature
• a measure of the average amount of kinetic energy of the particles in an object
Conduction
• the transfer of heat energy from one object to another when they are touching
Convection
• the transfer of heat energy from the movement of particles in a gas or a liquid
Radiation
• the transfer of heat energy through electromagnetic waves
Conductor
• an object or material that transfers energy easily
Insulator• an object or material that doesn’t transfer
energy easily
