Energy types Flashcards
What is energy?
Energy is the ability to do work.
What are the major types of energy?
Movement, heat, chemical, electrical, gravitational, light, nuclear, elastic, and sound. They are either kinetic or potential energy.
What is the unit used to measure energy?
Joules(J)
What does the law of conservation of energy state?
Energy cannot be created or destroyed, only transferred and transformed
Define kinetic energy
Energy that can be seen doing something
Define potential energy
Energy that is stored and has potential to be used for movement
What are the different potential energy?
Chemical, Gravitational, Nuclear, Elastif
What are the different kinetic energy
sound, movement, light, heat, electrical
Define chemical energy
Energy stored within substance, such as fuel or food, that may be released when the substance is burnt or digested
Define gravitational energy
The stored energy in an object that is held above the surface of the Earth
define nuclear energy
energy stored in the nucleus of an atom
define elastic energy
Energy stored in compress or stretched objects
Define sound energy
travel as vibrating waves and can be heard by our ears as sound
Define movement energy
Energy of moving object
Define light energy
Energy in electromagnetic spectrum
Define heat energy
Measure of total kinetic energy possessed in a substance
Define electrical energy
Energy that cause charged particles to move
Law of conservation of energy
Energy cannot be created or destroyed, only transferred or transformed.
What is temperature
Temperature is a measure of the average kinetic energy of the particles
What is heat
Heat is form of energy. Heat describes the total energy of all particles within an object
