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

(Cambridge IGCSE Physics ….Syllabus 2013)

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

howa fi group 3al facebook ????

• Hany El-Gezawy says:

look down
u will be there

2. shaimaa shehab says:

does the notes include all these points or shall i study from the book!!!

• Hany El-Gezawy says:

sure it contains everything in the last page (CORE)
and these points explained in my notes and the book
but for sure
Main concepts are in the notes

3. Rahma Baher says:

Is the weight costant alover earth’s surface?

• Hany El-Gezawy says:

No
but for us (in core) it is constant
and the value of “g” is 10 N/kg

4. Rahma Baher says:

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

• Hany El-Gezawy says:

students are classified into taller and shorter
students are classified into girls and boys
it depends on the question YA RAHMA

• Rahma Baher says:

ok ya Mr
hwa el exam hayeegy till page kam??

5. Rahma Baher says:

ya Mr hwa el “k” beta3et el kilo small wala big???
