Form 5 Physics applies Form 4 ideas to springs, circuits, magnetism and atoms. Each chapter leans on something earlier, so a gap in the foundations comes back in a new topic.
This route belongs to SPM Physics. If you need to revisit the earlier year, the Form 4 learning route lists the foundations.
How does a Form 4 idea reappear in Form 5?
Here is an original graph-to-equation example. A spring’s force-extension graph is a straight line through the origin, with F = 6.0 N at x = 0.030 m.
The gradient is 6.0 ÷ 0.030 = 200 N m⁻¹. The equation is F = 200x, which is Hooke’s law with k = 200 N m⁻¹. The energy stored at that extension is the area of the triangle, ½ × 6.0 × 0.030 = 0.090 J.
The graph skills (gradient and area) come from Form 4, and the equation and energy come from force and motion II. If you can read the graph, the new chapter is the same skill in a new setting.
What is a sensible study order?
Follow this order unless your school sets another.
- Force and motion II: components, resultants, equilibrium, springs.
- Pressure: force per area, using the force ideas.
- Electricity: current, voltage, resistance and power, using the energy idea.
- Electromagnetism: force on a current and induction, using force and electricity.
- Electronics: diodes and transistors, using circuit ideas.
- Nuclear physics: atoms and radiation, with its own reasoning and vocabulary.
The chapters are listed below this page. Early chapters feed the later ones, so electricity gets easier once force and energy are secure.
Who should start where?
If forces at angles or springs are unclear, start with force and motion II. If you are short of time, read the exam guide first to see how answers are assessed, then work on the chapters that carry the most uncertainty.
A teacher can start from the mistakes in your own work. See online one-to-one Physics tuition for how lessons start.
