Physics 2
Classical physics
The aims of the training are to enable the apprentice to- describe homogeneous and inhomogeneous electric fields and apply Coulomb’s law
- describe homogeneous and inhomogeneous gravitational fields and apply Newton’s law of universal gravitation
- describe magnetic fields around permanent magnets and electric currents, and calculate the magnetic flux density around a straight conductor and the force on a conductor in a magnetic field
- give an account of the term magnetic flux and apply Faraday’s induction law
- use Newton’s laws in vector form for motion in homogeneous magnetic fields and in a homogeneous gravitational field
- calculate acceleration and forces on objects that move at constant velocity in a circular path, and on objects at the top and bottom of a vertical circular path
- execute calculations with the law of conservation of momentum for one-dimensional collisions
Modern physics
The aims of the training are to enable the apprentice to- give an account of the postulations that form the basis for the special theory of relativity, discuss qualitatively some of the consequences of this theory for time, momentum and energy, and give a qualitative description of the general theory of relativity
- give an account of Einstein’s explanation of photoelectric effect, and give a qualitative account of how results from experiments with photoelectric effect, Compton scattering and the wave nature of particles represents a break with classical physics
- give an account of conservation laws that apply in processes with elementary particles, and describe the interaction between elementary particles
- give an account of Heisenberg’s uncertainty relations, describe the phenomena ”entangled photons” and give an account of their cognitive consequences
Explaining nature through mathematics
The aims of the training are to enable the apprentice to- describe the path of a particle using parameter presentation, and use derivation and integral calculus to work out position, velocity and acceleration when one of the three quantities is known
- use integral calculus to determine work and change in potential energy in central fields and for a spring that stretches
- analyze different mathematical models for a physical situation, with and without digital tools, and assess which model best describes the situation
The young researcher
The aims of the training are to enable the apprentice to- elaborate on and discuss how various theories of physics can exist side by side, even though they are contradictory
- give an example of a scientific conflict that has been resolved and how, and an example of a scientific conflict that remains unresolved and why
- carry out relevant experiments in the main subject areas, with and without digital tools
- estimate uncertainty in collected data and calculate the uncertainty in the final result
- assess the limitations of a chosen method and equipment and propose improvements and further experimentation
Physics and technology
The aims of the training are to enable the apprentice to- elaborate on technological applications of induction
- describe physical principles behind medical examinations such as X-rays, ultrasonography and magnetic resonance imaging
- elaborate on sampling and digital processing of sound
