Conservation of energy Flashcards
1
Q
The 8 energy stores
A
1) Kinetic
2) Thermal
3) Chemical
4) GPE
5) Elastic potential
6) Electrostatic
7) Magnetic
8) Nuclear
2
Q
4 types of energy transfer
A
1) Mechanically
2) Electrically
3) By heating
4) By radiation
3
Q
The conservation of energy states
A
Energy cannot be created or destroyed, only transferred and dissipated between stores. The total energy of a closed system has no net change.
4
Q
Principle of energy usefulness
A
Energy is only useful when it is transferred from one store to a useful store
5
Q
The law of conservation of energy
A
Total energy input = useful energy output + wasted energy
