Science Of 14-16 Flashcards
Energy
Conservation
Preserving or protecting
What happens when energy is taken from a system and converted or changed
When energy is transferred 2 another system it can be changed or converted from one form to another
What happens to biological systems when we move
The stored energy changes to kinetic energy when we move
Explain the law of conservation of energy
Energy can’t be created or destroyed, it can only be transformed from one form to another
Where do hydro electric power stations store water
Usually the water is stored high up in dams
Explain a system of heps
POTENTIAL ENERGY IN DAMS kinetic energy in water flowing in pipes KINETIC ENERGY IN TURNING GENERATORS kinetic energy in power lines
Show an exp. of transfer within systems of a steam engine
POTENTIAL ENERGY IN COAL heat energy in water HEAT ENERGY IN STEAM kinetic energy in pistons KINETIC ENERGY IN WHEELS
Show an exp. of an energy transfer between systems
When a person(biological system) pedals a bike(mechanical system) energy is transferred through the bike
Show an exp. Of transfer between systems in a line…
ELECTRICAL ENERGY IN ELECTRIC CIRCUIT kinetic energy in fan motors KINETIC ENERGY IN FAN SHAFT kinetic energy in fan blades
Heat
A type of energy which makes things feel warm
Temperature
A measurement of how much heat energy some thing has in it
Thermonoter
A instrument of how much heat energy something has
Why do things feel warm
They feel warm because they contain heat energy
Is heat the same as temperature
No
What is temperature a measurement of
Of how hot or cold something is
