準備建議
- Strengthen Your Foundations: Master the core concepts and formulas for each chapter, with extra focus on areas where you feel less confident.
- Practice Past Exam Questions: Work through previous exam papers and practice questions from study guides to become familiar with the format and time management. Keep track of mistakes to identify areas for improvement.
- Enhance Experimental Skills: Gain proficiency in common physics experiments by learning how to design experiments, select appropriate equipment, write procedures, and analyze data independently.
- Leverage Resources:
- Refer to official textbooks and course descriptions for a comprehensive understanding of the exam scope.
- Use free or paid online practice question banks to strengthen your preparation.
- Join online or in-person tutoring or review classes for expert guidance.
- Time Management: Create a detailed study schedule, allocating time effectively to ensure all topics are thoroughly reviewed before the exam.

Sample Questions
Physics Questions
Question 1
The root-mean-square speed of the atoms of a monatomic ideal gas at a temperature of 200 K is vrms. At a later time, the root-mean-square speed of the atoms is 2vrms. What is the temperature of the gas at this later time?
(A) 800 K
(B) 400 K
(C) 200 K
(D) 50 K
Physics Questions
Question 2
A truck is traveling to the east with a speed of 25 m/s relative to the road while emitting a loud sound with a single frequency. The figure shows four different observers and indicates their locations and velocities relative to the road. Which observer hears a sound with the highest frequency?
(A) A
(B) B
(C) C
(D) D
Physics Questions
Question 3
The figures show two different capacitors made of identical parallel conducting plates. In Capacitor 1, the plates are separated by a distance d and a block of material with dielectric constant κ is inserted between the plates. In Capacitor 2, the plates are separated by a distance 2d and two identical blocks of material with dielectric constant κ are inserted between the plates. A student claims that the capacitance of Capacitor 2 is the same as that of Capacitor 1. Which of the following indicates whether the claim is correct or incorrect, and provides a valid justification?
(A) Correct, because the effects of doubling the distance between the plates and doubling the volume of the dielectric cancel each other.
(B) Correct, because the capacitance is a property of the plates and the plates have not changed.
(C) Incorrect, because doubling the thickness of the dielectric material will cause the capacitance to double.
(D) Incorrect, because doubling the distance between the plates will reduce the capacitance by half.
Physics Question
Question 4
At time t = 0, a sample of radioactive material with decay constant λ has N0 nuclei. At time t = t1, there are N1 nuclei remaining. At a later time t = t2, there are N2 nuclei remaining. Which of the following correctly relates N2 to N1?
(A) N2 = N1 e-λ(t2 – t1)
(B) N2 = N1 e-λ(t2 + t1)
(C) N2 = (N1/N0) e-λ(t2 – t1)
(D) N2 = (N1/N0) e-λ(t2 + t1)
