Energy and storage systems Flashcards
1
Q
what is the conservation of energy
A
energy is never used up, it’s just transferred between different energy stores
2
Q
All 8 energy stores
A
- thermal energy
- kinetic energy
- gravitational potential energy
- elastic potential energy
- chemical energy
- magnetic energy
- electrostatic energy
- nuclear energy
3
Q
How is energy transferred
A
mechanically ( by a force of doing work) or electrically (work done by moving charges) or by heating or radiation
4
Q
what is a closed system
A
a system where energy or matter cant enter or leave, the total energy of a closed system is 0
5
Q
example of energy being transferred by heating
A
- kettle
- by boiling water, energy is transferred to the water by heating, into the thermal energy store, causing temperature to rise
6
Q
what is a system
A
an object or a group of objects
