ohhh u kno i tok al together AS and A in 1 year and the prb in my phy unit 1 i hve a D and i didn resit it

Here: maybe this checklist may help u glance through

Electric and magnetic fields:
- what r uniform fields? what is electric field strength and what does it depend on..
- drawing radial and parallel fields
- derive E = kQ/r^2
- how to prove a uniform field btw 2 plates
- experiment for C=Q/V
- Area under Q-V graph is work done
- growth and decay curve shapes for capacitors
- time constans RC helps to know how fast it will discharge
- magnetic flux density, flux and flux linkage
- Fleming's LHR and F=BIl sin (theta) or F= BQV sin (theta)
- transformers
- factors affecting current induced in a coil
- explain how the induced emf eqn relates to Lenz n Faraday's Lws

Particle Physics
- alpha scattering experiment
- thermionic emission
- Cyclotrons and linacs (concept.. gap btw the dees, why the length of pipe inncreases etc..)
- r = p/BQ
- particle traks: unionized particles leave no tracks, momentume is conserved, and so is charge)
- E=mc2
- Relativistic effects when interpreting particle reactions
- every particle has an anti=paricle, baryons have three quarks and mesons have one quark and 1 anti-quark
- de Broglie's equation
