Energy Flashcards
Kinetic
The energy possessed by objects that are moving
Potential Energy
the energy that has the potential to do work and so the energy is ‘stored’
Thermal
Energy that causes objects to gain temperature
Light
Energy that may be released when object is hot
Gravitational
Potential energy of an object when elevated above the ground
Chemical
Energy stored in chemical which react together
Electrical
energy made available by flow of electric charge through conductors
Sound
carried by air and detected by ear
Elastic
Stored by an elastic object that is streched
Nuclear
Stored in nucleus of atoms that release energy slowly
Law of Conservation
- Energy can’t be destroyed
- All object posses energy
- Energy can be stored
Transform
One type to another
Transfer
One object to another
Conduction
vIbration and collision of particles
Convection
Through the mass movement of the flow of gases and liquids.
Heat and Cold air
Heat rise, Cold fall
Radiation
Through the movement of an electromagnetic wave which does not require particles
Reverberation
Longer lasting sound caused by repeated reflection from hard surfaces
Potential Energy Types
Gravitational, Chemical, Elastic, Nuclear
Luminous
Make own light- torch
Incandescent
Emit light through heat-sun
Bioluminescent
Produce light naturally- anglerfish
Non-luminous
Do not emit light but reflect it, moon
How can light be seen?
Scattered
3 ways light can be seen and travel
Reflected, Transmitted, Absorb, Bounces off objects
Insulator
The object that prevents conduction
Sound Traveling
THrough vibrations
Rarefaction
The process which particles spread apart between compressions
