Contoh Soalan Fizik Tingkatan 4 |link| [ 2025-2026 ]

Which of the following is a base quantity in the International System (SI) of units? A. Velocity B. Force C. Temperature D. Work Answer: C (Temperature – base quantity; others are derived) Contoh Soalan Struktur (Structured Question): Diagram 1 shows a micrometer screw gauge reading. Determine the diameter of a wire. (Assume an image showing main scale = 5.5 mm, thimble scale = 28 divisions → 0.28 mm) Calculation: 5.5 + 0.28 = 5.78 mm 2. Force and Motion (Kinematics & Dynamics) Topic Focus: Linear motion equations, inertia, momentum, Newton’s Laws, impulse, and forces in equilibrium.

Below is a breakdown of typical questions by topic, including objective, structured, and essay-type formats. Topic Focus: Base quantities, derived quantities, scalar/vector quantities, and measurement instruments (vernier calipers, micrometer screw gauge). contoh soalan fizik tingkatan 4

Which material has the highest specific heat capacity ? A. Iron B. Water C. Aluminum D. Mercury Answer: B (Water, ( \approx 4200 , \text{J kg}^{-1} \text{°C}^{-1} )) Contoh Soalan Esei: In an experiment, 2 kg of water at 30°C is heated by a 500 W immersion heater for 10 minutes. Calculate the final temperature of the water. (Specific heat capacity of water = ( 4200 , \text{J kg}^{-1} \text{°C}^{-1} )) Solution: ( Q = mc\Delta\theta \rightarrow Pt = mc\Delta\theta ) → ( 500 \times 600 = 2 \times 4200 \times \Delta\theta ) → ( \Delta\theta = 35.7°C ) → Final temp = 65.7°C. 5. Waves Topic Focus: Transverse/longitudinal waves, wave equation, reflection, refraction, diffraction, and interference (water, sound, light). Which of the following is a base quantity

A satellite of mass 500 kg orbits Earth at a height where gravitational acceleration is ( 8.0 , \text{N/kg} ). Calculate the gravitational force acting on the satellite. Solution: ( F = mg = 500 \times 8.0 = 4000 , \text{N} ) 4. Heat Topic Focus: Specific heat capacity, latent heat, thermal equilibrium, and gas laws. Force C

A wave has a frequency of 50 Hz and a wavelength of 0.2 m. Calculate the wave speed. Solution: ( v = f\lambda = 50 \times 0.2 = 10 , \text{m/s} ) Contoh Soalan Esei (SPM-style): Diagram shows two coherent sources of water waves producing interference pattern. Explain why alternating constructive and destructive interference occurs. How does increasing frequency affect fringe spacing? 6. Light and Optics Topic Focus: Reflection (plane/curved mirrors), refraction (Snell’s law), total internal reflection, lenses (convex/concave), and optical instruments.

Form 4 Physics is the foundation for understanding the physical principles of the universe. The syllabus is structured around key themes: measurement, motion, forces, heat, waves, light, and optics. Mastering sample questions from each topic is crucial for SPM success.
