Form 4 Physics builds the tools that the rest of the syllabus uses: units, graphs, forces and energy. The chapters are not isolated, and each one gives something to the next.
This route belongs to SPM Physics. When you finish it, continue with the Form 5 learning route.
How does one Form 4 idea carry forward?
Here is an original graph-to-equation example. A trolley’s velocity-time graph is a straight line from 4 m s⁻¹ at 0 s to 14 m s⁻¹ at 5 s.
The gradient is (14 − 4) ÷ 5 = 2 m s⁻². The line’s equation is v = 4 + 2t, which matches the equation of motion v = u + at with u = 4 and a = 2. Choosing that equation is reasoned, not remembered: the graph supplied u and a.
The same gradient-and-area reading returns in force and motion I, in gravitation for falling objects, and in heat for temperature-time graphs.
What is a sensible study order?
Follow the route in this order.
- Measurement: units, scalar and vector quantities, and the habit of writing units.
- Force and motion I: describing motion, equations, momentum, forces and energy.
- Gravitation: weight, field strength and orbits, using the force ideas.
- Heat: energy transfer and temperature, using the energy idea.
- Waves, then light and optics: wave description first, then rays and lenses.
The template lists each chapter below. The order matters most at the start, since a shaky grasp of units or graphs travels with you through later chapters.
Who should start where?
If you are new to Physics, begin with measurement and then force and motion I. If you already finished force and motion, check your work on selecting and checking a physical model to see whether your reasoning holds up under unfamiliar questions.
If you are unsure about a chapter, use the chapter practice sets as a diagnostic. A teacher can work from your own mistakes if you want that, and online one-to-one Physics tuition shows how lessons start.
