Physics Paper 6 Notes

Note : Some of this is not applicable to IGCSE Physics, as it has been submitted by an O-Level Student, but is nonetheless useful.

Calculation 

1. 
   Addition and Subtraction : same number of decimal places as the number with the least. 
   
2. 
   Multiplication and Division : same number of sf as the number with the least. 
   

Graphs 

• 
  Draw and label the axis’
  
• 
  Give the graph a title 
  
• 
  Ensure that the scale is clearly marked out 
  
• 
  Ensure that the graph covers more than 50% of the paper. 
  

y

x

• 
  Y is directly proportional to x 
  

y

 x

• 
  Y is linearly related to x 
  

y

x

• 
  Y is linearly related to x with a negative gradient 
  

y

x

• 
  When x is increased, y increases at a decreasing rate 
  

y

 x 

• 
  When x is increased, y decreases at a decreasing rate 
  

y

x

• 
  When x is increased, y increases at an increasing rate 
  

y

x

• 
  When x is increased, y decreases at an increasing rate
  

When asked for gradient : magnitude and unit 

When asked for constant g : only the magnitude
