Energy Stores Flashcards
What is the law of Conservation of Energy?
Energy cannot be created or destroyed, but is transferred from one store to another.
What changes in the Law of Conservation Energy?
The amount of energy in the stores.
What is the definition and example of the Chemical energy store?
Anything with stored energy which can be released by a chemical reaction.
eg, batteries
What is the definition and example of the Kinetic energy store?
The energy of a moving object
eg, anything moving
What is the definition and example of the Gavitational Potential energy store?
The energy of an object at height
eg, book on high shelf
What is the definition and example of the Thermal energy store?
Is produced when a rise in temperature causes molecules and atoms to move faster and collide.
eg, hot water
What is the definition and example of the Elastic energy store?
The energy stored when an object is stretched or squashed.
eg, clockwork toys
What is the definition and example of the light energy store?
Any luminous given off.
eg, light bulb
What is the definition and example of the sound energy store?
Anything that gives off noise
eg, music
What is the definition and example of the Electrical energy store?
Wherever there is a current flowing there is electrical energy
eg, anything using electricity
What is the definition and example of the Nuclear energy store?
Released only from nuclear reactions
eg, nuclear bombs
What energy is lost and what energy is gained in the picture below:
How long can energy stay in the same store for?
millions of years to just a fraction of a second
What happens when an energy system changes?
There is a change in the way some or all of the enrgy is stored.
What is the definition of energy?
Energy is defined as the ability to do work
