Energy Types Flashcards
(15 cards)
What is Kinetic Energy?
Energy of MOTION
Kinetic energy is the energy possessed by an object due to its motion.
What is Electrical Energy?
The energy of moving electric charges
Examples include lightning and electrical appliances.
What is Radiant Energy?
Energy that travels as electromagnetic waves
Examples include UV waves, sunlight, and microwaves.
What is Sound Energy?
Energy given off by vibrating objects
Examples include videos, music, and horns.
What is Mechanical Energy?
Energy of motion to do work
Examples include machines, the human body, and motors.
What is Thermal Energy?
Energy of moving particles
Examples include heat, ovens, and body temperature.
What is Potential Energy?
STORED Energy (not moving)
Potential energy is the energy stored in an object due to its position or state.
What is Chemical Energy?
Energy stored in atoms’ bonds
Examples include food and fuel.
What is Nuclear Energy?
Energy stored in the nucleus of atoms
Examples include power plants and stars.
What is Gravitational Energy?
Energy of position
Example includes a roller coaster at the top of a hill.
What is Elastic Energy?
Energy stored due to force
Examples include rubber bands and springs.
What is the Law of Conservation of Energy?
Energy cannot be created or destroyed; it can only be CHANGED
Energy can transform from one form to another, such as light to chemical or thermal to mechanical.
What is Conduction?
Energy is transferred by direct contact
This occurs when two objects at different temperatures touch each other.
What is Convection?
Energy is transferred by the mass motion of fluids
This process occurs in liquids and gases.
What is Radiation?
Energy is transferred by electromagnetic radiation
This includes the transfer of energy through space without the need for a medium.
