non renewable energy
energy that will be used up eventually
fossil fuels
fuels that were made from living matter a very long time ago
global warming
gradual increase in earths temp because, gases like caborn dixocide ,reaslesed when fossil fuels are burnt, trap radiation in the earths atmossphere
energy
the ability of a system to do work
renewable energy
energy that cant be used up/exhausted
joule
unit used to measure energy
potenial energy
energy stored in object/system
Chemical potenial energy
energy stored in particles of a substance
Elastic potenial energy
energy stored in a stretched or compressed object
Gravitational potenial energy
potenial energy that is stored in an object because of its postion above earth
At rest
not moving
Kinetic energy
energy that an object has because it is moving
Energy system
different parts that work together to store, use or give out energy so that a specific task can be done
Energy transfer
movement of energy from one object to another or the change of energy from one form to another
temperture
how hot or cold an object is
mechanical system
system that use force and movement to do a specific task
thermal energy
energy produced by heat
conservation of energy
the same amount of energy will be present at the end of a reaction or processed , as there was in the begining
heat
energy that an object has because of the movement of particles that make up the object
Conduction
transfer of heat betwwen solid objects that are in direct physical touch
conductors
substances that transfer heat energy easyily
insulators
substances that dont transfer heat energy easlily
variables
factors that can change, are observable and measureable
fixed variable
variable that is kept constant every time the investigation is conducted
