1.1 MEASUREMENT IN PHYSICS

Understandings:

• Fundamental and derived SI units
• Scientific notation and metric multipliers
• Significant figures
• Orders of magnitude
• Estimation

Applications and skills:

• Use SI units in the correct format for all required measurements, final answers to calculations and presentation of raw and processed data
• Use scientific notation and metric multipliers
• Quote and comparing ratios, values and approximations to the nearest order of magnitude​

Guidance:

• Analysis of uncertainties will not be expected for trigonometric or logarithmic functions

Utilization:

• All group 4 subjects

Data booklet reference:

• ​Metric (SI) multipliers can be found on page 5 of the physics data booklet

1.2 UNCERTAINTIES AND ERRORS

Understandings:

• Random and systematic errors
• Absolute, fractional and percentage uncertainties
• Error bars
• Uncertainties of gradient and intercepts

Applications and skills:

• Explain how random and systematic errors can be identified and reduced
• Collect data that include absolute and/or fractional uncertainties and state these as an uncertainty range (expressed as: best estimate ± uncertainty range)
• Propagate uncertainties through calculations involving addition,
  subtraction, multiplication, division and raising to a power
• Determine the uncertainty in gradients and intercepts

Guidance:

• Analysis of uncertainties will not be expected for trigonometric or logarithmic functions

Utilization:

• All group 4 subjects

​1.3 VECTORS AND SCALARS

Understandings:

• Vector and scalar quantities
• Combination and resolution of vectors

Applications and skills:

• Solve vector problems graphically and algebraically

Guidance:

• Resolution of vectors will be limited to two perpendicular directions
• Problems will be limited to addition and subtraction of vectors and the multiplication and division of vectors by scalars

Utilization:

• Navigation and geographical surveys
• Force and field strength

Data booklet reference:​​

Practice and review:

• Watch Youtube on scalars and vectors
• Watch Youtube video discussing the difference between scalar quantities (distance, speed, etc.) differ from vector quantities (displacement, velocity, etc.)

• Watch Youtube on resolving vectors into components

• Watch video on adding vectors
