Energy Flashcards
What is energy
The ability to do something
Law of conservation
Energy cannot be created or lost but It can be transformed or transferred
Potential energy
Stored energy that gets converted
Gravitational energy
Potential energy of an object elavated above the ground
Elastic energy
Energy store by an elastic object that springs
Chemical energy
Stored in chemicals that when reacted together result in an action
Nuclear energy
Energy stored in the nucleus of atoms that slowly release energy
Electrical
Energy made available by the flow of electric charge through a conductor
Kinetic
Energy passed by loving object
Heat
Energy that causes an object to gain temperature
Light
Energy that may be released, for example when an object is hot
Sound
Energy carried by the air in a room and detected by the ear
Efficiency
The fraction of energy supplied to a device as useful energy. Expressed as percentage
Conduction
Transfer of heat through collision between particles
Happens when objects are touching
Convection
Transfer of heat through flow of particles
Doesn’t require object to be touching
