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/second2 (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 output

 108 - 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:

gravitational potential energy = mass × g × height

GPE = m × g × h

kinetic energy = ½ × mass × speed2

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 / t

 104-105

15

understand the energy transfers involved in generating electricity using:

  • wind

  • water

  • geothermal resources

  • solar heating systems

  • solar cells

  • fossil fuels

  • nuclear power

 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
