Energy Stores And Systems Flashcards
What is kinetic energy
Anything moving has energy in its kinetic energy store
What is thermal energy
All objects have this, the hotter the object the more energy it has
What is meant by chemical energy
Anything that can release energy by a chemical reaction
What is gravitational potential energy
Objects raised above the ground
What is elastic potential energy
Anything that is stretched e.g rubber bands
What is electrostatic
Two charges that attract or repel each other
What is magnetic energy
Two magnets that attract or repel each other
What is meant by nuclear energy
The nucleus of an atom releases energy
What does it mean for energy to be transferred mechanically
When a force does work e.g pushing an object along the floor
What does it mean for energy to be transferred electrically
This is when a moving charge does work e.g when a current flows through a light bulb
What does it mean for energy to be transferred by heating
When energy is transferred from a hotter object to a colder object
What does it mean for energy to be transferred by radiation
When energy is transferred by sound or light
