To students taking Physics O Level Paper 1, do take note of the following. Given what has been tested in Paper 2 already, we can hypothesize the concepts that may be tested in Paper 1, as follows:

1) Reading of vernier caliper, micrometer, ticker tape, pendulum

2) Kinematics (graphs) and terminal velocity concepts

3) Forces calculation (Net F=ma)

4) Moments calculation & stability concepts

5) Mass, weight, density (and inertia)

6) Pressure: Barometer, manometer, hydraulic press (P=F/A, P=hpg)

7) Temperature (e.g. thermocouple), Brownian motion concepts

8) Heat capacity & latent heat (graphs, concepts, calculations)

9) Reflection, refraction & TIR, Lenses

10) Waves: v = fλ calculations, concepts, graphs

11) EM waves conceptual understanding

12) Sound: calculations. i.e. echo, graphs, pitch & loudness, ultrasound

13) Current electricity: formulae, series & parallel, brightness of bulbs

14) D.C circuits: potential divider, LDR, thermistor, potentiometer

15) Electromagnetism: Fleming’s LH rule, right hand grip rule, D.C motor

16) EMI: Lenz’s law, A.C generator, transformer, power transmission

17) CRO displays: Time-based on switched off or on (d.c input, a.c input)

All the best!
