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
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. A car accelerates from rest at ( 2
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. ( 2 , \text{m/s} ) B
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).
