PHYICS PRACTICAL FOR O LEVEL

This Session has tried to cuter many areas in ordinary level physics where the practical demonstration is of most important.

The experiments in this Session comprises of mechanics

The session also highlighted all the possible sources of errors in every experiment.

Most of the topics and experiments explained in this book are in accordance of ordinary level physics secondary school syllabus

Key Skills Assessed

Apparatus Handling – Correct use of instruments (e.g., ammeter, voltmeter, stopwatch).
Data Recording – Accurate measurements with appropriate units and significant figures.
Graph Plotting – Drawing graphs with correct scales, labels, and best-fit lines.
Calculations – Using formulas (e.g., gradient, percentage error).
Conclusion & Evaluation – Interpreting results and identifying sources of error.

Tips for Success

✅ Practice Past Papers – Familiarize yourself with common experiments.
✅ Learn Lab Equipment – Know how to use a micrometer, vernier caliper, etc.
✅ Precision Matters – Record measurements to the correct decimal places.
✅ Graph Skills – Label axes, use appropriate scales, and draw smooth curves.
✅ Time Management – Allocate time wisely between experiments.

Common Mistakes to Avoid

Incorrect Units – Always write units (e.g., cm, s, V).
Poor Graph Scaling – Avoid awkward scales (e.g., 3, 6, 9 instead of 2, 4, 6).
Ignoring Errors – Discuss possible inaccuracies (e.g., parallax error, friction).
Rushing – Read instructions carefully before starting.

In this book, all units and measurements have been brought into line with international recommendation.

A system of international units has been applied in all experiments
