Physics 1
Classical physics
The aims of the training are to enable the apprentice to- identify contact forces between objects and gravitational forces on objects, draw force vectors and apply Newton’s Three Laws of Motion
- give an account of the concepts of energy, work and effect, carry out arithmetic calculations and discuss situations where mechanical energy is conserved
- give an account of situations where friction and air resistance mean that the mechanical energy is not conserved, and perform calculations in situations with constant friction
- state and discuss the first and second laws of qualitative thermophysics
- define the terms current, voltage and resistance, and apply the principles of conservation of charge and energy to simple and branched direct current circuits
- define and carry out calculations with the terms frequency, period, wavelength and wave speed, and explain qualitative bending and interference phenomena
Modern physics
The aims of the training are to enable the apprentice to- describe Bohr’s atom model and use it to work out frequencies and wavelengths of spectral lines in emission and absorption spectra
- use conservation laws to describe fission and fusion processes and calculate the energy released in such processes
- apply Stefan-Boltzmann’s law and Wien’s displacement law
- give an account of how information about stars are systemized in an HR diagram
- describe the life-cycle of a star and explain how elements are produced in stars
- describe and discuss the standard model for the evolution of the universe
Explaining nature through mathematics
The aims of the training are to enable the apprentice to- use parameter presentation to describe the rectilinear movement of a particle, and use derivation to calculate velocity and acceleration when the position is known, with and without digital tools
- create one or more mathematical models for correlations between physical quantities found experimentally
- use mathematical models as sources for qualitative and quantitative information, present results and evaluate the area of validation of the models
The young researcher
The aims of the training are to enable the apprentice to- elaborate on and discuss key features of scientific method in physics
- give examples of some explanation models that are inconsistent with physics, nor based on scientific methodology
- give an account of how a researcher’s approach, expectations and experiences can affect research
- plan and implement experiments and carry out relevant experiments within the various main subject areas
- collect and process data and present and evaluate the results and conclusions of experiments and investigations, with and without digital tools
- use simulation programs to show phenomena and physical relations
Physics and technology
The aims of the training are to enable the apprentice to- give an account of the difference between conductors, semi-conductors and insulators based on the current atom model, and explain doping of semi-conductors
- compare the construction of a diode and transistor, explain how they work, and give examples of their use
- give an account of how light detectors work in digital photography or digital video
- give an account of how modern sensors are characterized, and how the sensors’ characteristics set limits for measurements
