Energy Resources & Transfers
under construction
The various syllabus statements cover very different quantities of material. I'm sorry there aren't any pictures yet. You need to read this page in conjunction with block 4 of the syllabus specification. xxx represents a page number in England, (3rd edition).
1 |
use the following units: kilogram (kg), joule (J), metre (m), metre/second (m/s), metre/second 2 (m/s2), newton (N), second (s), watt (W)98-113 |
2 |
describe energy transfers involving the following forms of energy: thermal (heat), light, electrical, sound, kinetic, chemical, nuclear and potential (elastic and gravitational) 98 -113 |
3 | understand that energy is conserved. |
4 |
recall and use the relationship efficiency = useful energy output / total energy output108 - 109 |
5 |
describe a variety of everyday and scientific devices and situations, explaining the fate of the input energy in terms of the above relationship, including their representation by flow diagrams. 108 - 109 |
6 |
recall that energy transfer
may take place by conduction, convection and radiation. 152-153 |
7 |
describe the role of
convection in everyday phenomena 150 - 151 |
8 |
describe how insulation is used to reduce energy transfers from buildings and the human body. 154-155 |
9 |
recall and use the relationship between work, force and distance moved in the direction of the force work done = force × distance moved W = F × d 98-99 |
10 |
understand that work done is
equal to energy transferred 98-99 |
11 |
recall and use the relationships: 2 KE = ½ × m × v2 102-103 |
12 |
understand how conservation of energy produces a link between potential energy, kinetic energy and work. 100-101 |
13 | describe power as the rate of transfer of energy or the rate of doing work. |
14 |
use the relationship between power, work done (energy transferred) and time taken power = work done / time taken P = W / t104-105 |
15 |
understand the energy transfers involved in generating electricity using:
112-113, 326-327 |
16 |
describe the advantages and disadvantages of methods of large-scale electricity production from various renewable and non-renewable resources. 112-113, 326-327 |
