# Expected Topics And Strategies To Questions In JAMB Physics

From my experience as a tutor and lecturer of physics, I know that there are some repeated topics in physics that JAMB can’t do without bringing out questions.

So, if you want to pass physics in JAMB and score above 60, you must master these topics and make sure you solve all possible questions on them.

I know that writing physics in the exam isn’t as easy as other subjects, but early preparation can help you build the muscle to score high in it.

## Expected Topics

1. Electric field
2. Expansivity questions
3. Direct current (D.C)
4. Work energy and power
5. Nuclear physics
6. Gas law
7. Current of electricity
8. Alternating current
9. Magnetic field and E.M induction
10. Questions and answers of Machine and light waves
11. Heat energy
12. Capacitance of a capacitor
13. Gravitational field
14. Stationary waves and Diffraction
15. Wave motion
16. moment of a force
17. Kinematics and deformation of solid
18. Measurement
19. Dynamics
20. Friction
21. Dimension Analysis
22. Fundamental and Derived quantities
23. Scalar and Vector quantities

## Questions to be expected

The questions below are extracted from JAMB past questions and it is intended to give you an idea of some UTME physics questions that do come out. If you checked 5 – 6 years past questions, you might notice some questions do appear repeatedly.
