General Physics


Chapter 1
Main Points (CORE)

• Use and describe the use of rules and measuring cylinders to calculate a length or a volume

• Use and describe the use of clocks and devices for measuring an interval of time.

• Show familiarity with the idea of the mass of a body

• State that weight is a force

• Demonstrate understanding that weights (and hence masses) may be compared using a balance

• Describe an experiment to determine the density of a liquid and of a regularly shaped solid and make the necessary calculation

(Cambridge IGCSE Physics ….Syllabus 2013)

Chapter 2
Main Points (CORE)

  • Define speed and calculate speed from total distance/total time
  • Plot and interpret a speed/time graph or a distance/time graph
  • Recognise from the shape of a speed/time graph when a body is
    • at rest
    • moving with constant speed
    • moving with changing speed
    • Calculate the area under a speed/time graph to work out the distance travelled for motion with constant acceleration
    • Demonstrate some understanding that acceleration is related to changing speed.
    • State that the acceleration of free fall for a body near to the Earth is constant
    • Understanding the weight of the body as a force and its relation to the force
    • Describe the ways in which a force may change the motion of a body
      • Find the resultant of two or more forces acting along the same line

Chapter 3
Main Points (CORE)

Turning effect

  • Describe the moment of a force as a measure of its turning effect and give everyday examples
  • Describe qualitatively the balancing of a beam about a pivot
  • State that, when there is no resultant force and no resultant turning effect, a system is in equilibrium. “Conditions for equilibrium”

Centre of mass

  • Perform and describe an experiment to determine the position of the centre of mass of a plane lamina.
  • Describe qualitatively the effect of the position of the centre of mass on the stability of simple objects.

Effects of forces

  • State that a force may produce a change in size and shape of a body
  • Plot extension/load graphs and describe the associated experimental procedure

Pressure

  • Relate pressure to force and area, using appropriate examples.
  • Relate the pressure beneath a liquid surface to depth and to density, using appropriate examples.
  • Describe the simple mercury barometer and its use in measuring atmospheric pressure.
  • Use and describe the use of a manometer.

(Cambridge IGCSE Physics ….Syllabus 2013)

Chapter 4
Main Points (CORE)

Energy

• Demonstrate an understanding that an object may have energy due to its motion or its position, and that energy may be transferred and stored

• Give examples of energy in different forms, including kinetic, gravitational, chemical, strain, nuclear, internal, electrical, light and sound

• Give examples of the conversion of energy from one form to another, and of its transfer from one place to another

• Apply the principle of energy conservation to simple examples

Work

• Relate work done to the magnitude of a force and the distance moved

Power

• Relate power to work done and time taken, using appropriate examples

• Show a qualitative understanding of efficiency.

 

Energy resources

• Distinguish between renewable and nonrenewable sources of energy

• Describe how electricity or other useful forms of energy may be obtained from:

– Chemical energy stored in fuel

– Water, including the energy stored in waves, in tides, and in water behind hydroelectric dams

– Geothermal resources

– Nuclear fission

– Heat and light from the Sun (solar cells and panels)

• Give advantages and disadvantages of each method in terms of cost, reliability, scale and environmental impact

    Is the weight costant alover earth’s surface?

  4. Rahma Baher says:

    Physical Quantities are divided into scalar and vector, or basic and derived ?
    And what’s the relation betwen both???
