Kinetic Energy
Energy stored in moving objects
-
Elastic potential energy
Energy stored as a result of applying a force to deform an elastic object
-
Gravitational potential energy
Energy stored due to it being above earth surface
-
Specific Heat Capacity
Amount of energy required to raise the temp of 1kg of a substance by 1degreecelcsisus
-
Thermal energy
Energy stored due to objects temperature
-
Law of conservation of energy
Energy cannot be created or destroyed - can be transferred stored or dissipated
-
How to cool buildings ( 2 )
Materials with a low thermal conductivity
Build a house with thick walls
-
Specific heat capacity practical
Place a beaker on a balance. Add oil to the beaker and find the mass. Place thermometer and immersion heater in oil. Read starting temperature. Wrap beaker in foam. Add a joule meter and a power pack. Leave for 30 mins. Read total number of joules and final temperature

-
2 advantages VS 2 disadvantages fossil fuels
Reliable
Release great deal of energy
VS
Finite resource
Releases huge amount of C02
-
2 advantages VS 2 disadvantages nuclear energy
Does not release C02
Extremely reliable
VS
Finite resource
highly dangerous radioactive materials
-
Renewable energy definition
Energy that can be replenished as its being used
-
3 renewable energy
