Contoh Soalan Fizik Tingkatan 4 //top\\ Here
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 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. contoh soalan fizik tingkatan 4
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. Which of the following is a base quantity
