Contoh Soalan Fizik Tingkatan 4 May 2026

A car accelerates from rest at ( 2 , \text{m/s}^2 ) for 5 seconds. What is its final velocity? A. ( 2 , \text{m/s} ) B. ( 5 , \text{m/s} ) C. ( 10 , \text{m/s} ) D. ( 25 , \text{m/s} ) Answer: C (( v = u + at = 0 + 2 \times 5 = 10 , \text{m/s} )) Contoh Soalan Esei (Essay): Explain why a passenger in a moving car lurches forward when the car suddenly stops. How does a seatbelt reduce the risk of injury? (Key points: Inertia – body continues moving forward due to Newton’s First Law. Seatbelt increases stopping time, reducing impulsive force according to ( F = \frac{\Delta p}{\Delta t} )) 3. Gravitation Topic Focus: Newton’s law of gravitation, gravitational field strength, weight, and satellites.

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 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. A car accelerates from rest at ( 2

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. ( 2 , \text{m/s} ) B

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.
